Samuel | May 2, 2023

Can only comment on the shipping and packaging... well done!

For Semtech LoRa SX1278 Data Radio Modem DRF1278DM

Shipping time was adequate, just as expected, no delays.

All 3 modules I ordered arrived in one bubble envelope, inside 2 of the 3 were labeled so the guess work on the 3rd was easy. The antennas were packaged separately and were labeled as well.
The chips were individually packaged appropriately, foam sandwiched in anti-static bags.

No documentation included (can one really expect paper documentation these days?) but their website seems to have it all very well done, easy to read. We'll see when I get them set up.

I can't wait for the rest of my gear to show up and if the packaging is any indicator, I can expect everything to work just fine.

Great first purchase on Tindie.

Works as expected, reasonable shipping time to Europe

For 868MHz 915MHz SX1262 Module DRF1262G

I purchased the 868MHz variant. The module arrived in reasonable time. I have only tested the LoRa modulation and it works rather well even with bad antenna and even worse ground plane. Power consumption in RX is 6mA from 3.3V with a uC, so yeah, according to the Semtech datasheet.

Great Genuine product

For Arduino 433Mhz Lora SX1278 Module DRF1278F

Great genuine product, not the fake / alternate XL1278-SMT that other suppliers provide. Great genuine product, not the fake / alternate XL1278-SMT that other suppliers provide.

Great modules, ordered multiple items? All in proper working

For 868MHz 915MHz sx1262 TCXO module DRF1262T FCC IC

These modules came packed in a carboard box with filling. Purchase both the 434 aswell as the 915mhz version.
Really was plug and play, the tcc works good, signal strength is better the comparable modules.
Hopefully they will also do an eu CEc vertification on them.

Currently have some running for months and still goiing strong.

Maybe even better tcc tolarance would benefit the signal more. But these are truly better than running a plain crystal. But these are solid will buy them again if i run out.

Works great but not easy to solder

For 868Mhz 915Mhz wireless RF si4463 module DRF4463F

Tried it to replace the costly Zeta modules from RF Solutions, and they do great, with better performances, at half the price!
However the pinout is very fine and hand-soldering is not easy, but doable. I'm also not sure which chip revision is inside, it's not mentioned in the docs but it would be useful to know.

A library for easy use with Arduino and Raspberry Pi is available: ZetaRf - https://github.com/GIPdA/ZetaRF (disclaimer - I'm the author).
The lib allows for very low latency (~4ms @ 8 bytes packet) but several configurations are available and you can use you own. Also compatible with the 433MHz variants.

Best SX1262 module

For 868MHz 915MHz sx1262 TCXO module DRF1262T FCC IC

This module is absolutely the best you can get. Price and design is unrivaled. TCXO is really accurate!

Barry | April 4, 2020

Good product, Good support

For 433MHz sx1268 TCXO module DRF1268T

I would highly recommend these for any low power, low bit rate, long range communications.

I am using these radio modules in some remote weather stations. They seem to meet all of their specs. They reliably transmit across 20 km using 10 mW transmit power (-10 dBm)*. I have only deployed two modules so far and have had no issues.

Current consumption when in power saving receive (using SetReceiveDutyCycle command) is well below 1mA (my measurement setup only goes that low, and I measure all components together - this is good enough for me so I stopped investigating at that point).

I also ordered the evaluation board. That is well thought out and came with everything necessary, including an antenna.

When I enquired about the details of the design - in particular I wanted to know which TCXO the units use** - Mark from Dorji responded promptly with the datasheet.

The product shipped from China within two days, and arrived in my mailbox in California 2 weeks later.

* I'm not using the ISM band, I found a quiet band I could transmit on without worrying about interference. I would not count on that sort of performance if using unlicensed bands.

** An important parameter if using these in their power saving ReceiveDutyCycle mode is how long the TCXO takes to stabilise, because it's only turned on intermittently. The oscillators used in this device take 2 ms to stabilise (which seems good and quick, but I'm no RF engineer).

Duane | March 4, 2020

Absolutely the best radios I've found for the price.

For 868MHz 915MHz 22dBm sx1262 UART TTL module

I have six of these now and they are the best LoRa units I have found at this price point.
Also they have unbelievable glitch free range and are fairly easy to set up.

I feel the only downside is that more Arduino example sketches would be helpful.

Excellent product at an excellent price equals a five star rating.

Andrew | Jan. 14, 2020

Nice little module working well so far.

For 868MHz 915MHz sx1262 TCXO module DRF1262T FCC IC

Bought this for a RC project of mine, up and running quickly. Questions to seller about TCXO config were answered quickly. Delivery was a little slow compared to other stuff ordered from China. Overall very happy and will be buying more.

Bernd | Nov. 21, 2019

Good replacement for the older RFM95/96 & SX127x chips/mods

For 868MHz 915MHz sx1262 TCXO module DRF1262T FCC IC

Perfect SX1262 LoRa module. Easy to use and very good range. Will definitely get more of them.
Only problem was to find Arduino libraries that support the SX126x chips. But RadioLib and SX126x-Arduino libraries are doing the job.

Bernd | Nov. 21, 2019

Perfect base to test the DRF1262T module I bought.

For sx1268 sx1262 testing kit for Arduino ST Nucleo

Easy to assemble.
The pins for the DRF1262T module were pre-tinned, so it was very easy to solder the module on the dev kit.

Murad | Nov. 13, 2019

Satisfied with service

For 868Mhz 915Mhz SX1276 module DRF1276G

Satisfied with product quality, service and seller communication. Seller my expectations on my purchase.

J.F. | Nov. 10, 2017

Wrong product delivered

For Arduino 433Mhz Lora SX1278 Module DRF1278F

Wrong product delivered, The advertisement will provide the DRF1278F module but received the XL1278-SMT module, Seller had no intention of replacing or compensate the wrongly delivered modules

Response from DORJI | Nov. 10, 2017

Dear Sir.,

We didn't receive any complaints about the wrong shipments by message or email yet. Could you be kind to tell me if you bought the modules from Tindie? The products here are all originated from DORJI directly. There are a lot of sellers in Ebay or Aliexpress who sell the fake parts. In other words, they advertised the keyword of DRF1278F but the pictures of the products are marked with other part names. I am looking forward to your further opinion soon.

Best regards,
Todd ZHOU

Simple module great price

For si7005Temperature & humidity sensor module DSTH01

You cant get the SI7005 any cheaper than this. The module works very well and is simple to interface to using a standard I2C protocol. Just follow the data sheet available on line.

Great product Highly Recommend it!

For 868MHz 915MHz SX1276 data radio modem DRF1276DM

Easiest to use product, great configuration tool by DORJI, just one thing though, Ground the "EN" pin ( I soldered a wire between "GND" and "EN" pin and it works like a charm! ). I got the package on 14th day after ordering it which is pretty cool for overseas transport. Fabulous support from DORJI (I mistakenly ordered 433MHz, which is not ISM band in India, but the lovely people at Dorji_Com switched it to 868MHz as soon as I contacted them on the same day of ordering ). Great product for beginner, Highly recommend it!

Got > 500 metres range in a slightly hilly urban setting

For Arduino 433Mhz Lora SX1278 Module DRF1278F

Wrote some Python code to test the range. At max range settings (BW=125KHz, SF=12, CR=4/5), it takes less than a second to transmit 5 bytes.
One transmitter was placed indoors in my bedroom, and I took a drive with the other plugged into my laptop via the SPI bridge of a SEELablet.
About 500 metres LoS acc to google maps, but the signal had to go through a couple of walls at least. Will test in an open area when time permits.
RSSI at maximum distance was -127

Used the included spring antenna, and set transmit power to 17db. Not sure how to enable 20db, or if it was enabled at all . No significant heating observed, and current consumption is about 60mA .

* This is a P2P LoRA connection . Not to be confused with LoRaWAN. I haven't implemented that protocol, nor do I have access to a gateway here

Jasveer | April 15, 2017

Very good product, immediate dispatch

For 868MHz 915MHz SX1276 data radio modem DRF1276DM

It is a very good product, they dispatch the shipment immediately but it takes very long time for it to reach me. First time i ordered, it had taken 20 days for the shipping. It would be best if we have more options for shipping it faster.

Mato | April 5, 2017

Good product range at 9600 bauds ~1.5km

For Semtech LoRa SX1278 Data Radio Modem DRF1278DM

This product come with a good packaging. Shipping at France is about two weeks.

I bought two of them and use them on two arduinos (Mega and Nano) and with a bit of research, I made a little "tchat" on Github : https://github.com/storca/SemtechLoRaSX1278ChatTTL

Range is about 1.5km through obstacles.

Awesome Product

For Arduino 433Mhz Lora SX1278 Module DRF1278F

If you want a small transceiver buy these because we have been using these in a prototype product soldered to a board with a arduino pro mini and a 3.3v power circuit run using a 18650 battery and have had zero problems. We tested the range and got 2 mile in an urban area through hills and large factorys using a little rubber duck antenna with out any problems , we have not had chance to test the max range yet but i believe we will be able to get much further i have seen people using this chip type to get 200km on high altitude balloons when using a low data rate here is some info http://www.picaxeforum.co.uk/showthread.php?26314-Semtech-s-LoRa-(Long-Range)/page3

so if you want a rock solid transceiver get some of these little bad boys

PS dorji we tried to message you before but got no reply about buying larger quantitys from you we are not looking for discounts just a more direct line of contact and purchasing of up to 100 at a time possibly every 2 - 3 months because we will be using at least 50 a month starting around March so please can you message us with some way of contacting you or should we contact you via http://dorji.com Thanks Mick

Looks awesome!

For 868MHz 915MHz SX1276 data radio modem DRF1276DM

Product looks very well, well packaged and lightning fast delivery. Track & Trace also very good! At a first look, they repond both to commands, a more extensive test will be done within two weeks. For now, I'm very exited to test both modules in a working environment. Tindie & Dorji: Both a 100 times thanks for this great product and the easy way to order it. Thumbs up!

Best regards from the Netherlands

Awesome communication modules, easy to work with.

For 868MHz 915MHz SX1276 data radio modem DRF1276DM

I ordered two of those modules and ended up to receiving three plus the USB program tool. I'm very grateful. :D
No more than two weeks shipping time to Portugal and with no problems with customs.
It's the easiest thing to star working with this modules. Basically plug and play. Unfortunately, I'm still unable to connect them to Dorji's configuration tool. I think the software is still only for the 433Mhz modules.

Good quality and packing!

For Semtech LoRa SX1278 Data Radio Modem DRF1278DM

I have ordered 2 modules and received it after 2 weeks. This product too small and can apply to drone or airplane rc for telemetry tracking.

DRF1278 DM module

For Semtech LoRa SX1278 Data Radio Modem DRF1278DM

Received 2 DRF1278 DM modules with USB to UART converter board. The items were very well packed .
The documentation is very minimal & took some research to figure out how things work.
It will be better if they provide heat shield as provided on other modules.
