DESCRIPTION

DRF1276DM is a type of long range low data rate data radio modem based on SX1276 from Semtech. DRF1276DM is a low-cost sub-1 GHz transceiver module designed for operations in the unlicensed ISM (Industrial Scientific Medical) and LPRD bands. Frequency spectrum modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking performance make DRF1276DM modules easy to realize the robust and reliable wireless link.

The module can work in two different modes: Standard mode and Star network mode. In the standard mode DRF1276DM acts as transparent data radio modem which it communicates with the host at the preset data format without encoding / decoding needed. In start network mode, one module will be the configured to the central module and other modules are set to node modules. The communication between the central module and node module are bidirectional but the node modules can not talk with each other.Please note that the module doesn't contain lorawan protocol. Therefore the star network feature of this module is used with itself protocol so it is not compatible with lorawan.

Note:

The price is for 1pcs of DRF1276DM and 1pcs of antenna.The DRF1276DM has wide working frequency range so it can be used in 868Mhz or 915MHz. However the bandwidth of antenna is limited. Therefore we offer 915Mhz antenna for customers from south America and north America by default. For other territories including Africa, Asia, Australia, Europe, etc, we will offer 868Mhz antenna by default. If customers need different antenna frequency, please leave the message in order page or send message to us in case we ship the mismatched antenna.

DRF1276DM

Modüller hızlı bir şekilde elime ulaştı. modülleri henüz deneme fırsatım olmadı. ama alışverişten memnun kaldım

Great product Highly Recommend it!

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!

Very good product, immediate dispatch

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.

No Invoice & Documentation

I have not received invoice with the product. I need to submit it in my office. The link provided by Tindie for PDF invoice is also not working.
Kindly provide the invoice as soon as possible. Also hard copy of the invoice should also be provided with the product.

Looks awesome!

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.

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 product

Ordered 3, got them in time (France), all working perfectly well. In the first testings, using pre-set mode (max power and almost max sensitivity), got 500m range through several buildings until the signal gets blocked by the hill the receiver is on top.
Expect "high" latency when used with high sensitivity/low baudrate (1 to 2 sec at -135dB/0.5kbps).

The usb-serial module provided use a CP2104, which works perfectly with some softwares (like CoolTerm) but not at all with the c++ serial library QSerialPort and all Android apps I tested. FTDI works well in all conditions.
