Tindie

Using this in a project to use Siri to actuate a garage door faraway from my house...

Vendor was very helpful, provided good technical support and the board just works ;)

Thanks!

Great value

Good value, well made, work well. I got an extra one too! The only improvement I can suggest is screen printing the pin ID on the top of the board. Thanks :)

Perfect board

I was looking for a cheap breakout board for my lora experiments. Received 3 instead of the 2 ordered (thanks). Wasn't sure to order without tracking but this is no problem. Took about 7 days to arrive in a padded envelope. Would buy again.

Excellent product and shipping

Very nice breakout board. Pins are well labelled. The antenna port is quite flexible in the sense that I can use either uFL or SMT connectors. It is hard to find this kind of boards from retailers in North America.

I was initially worrying about the shipping since there is no tracking. However, it only took a week shipping from France to Canada as a registered mail. The packaging was pretty good and all the boards were intact upon arrival.

great board for TTN V.3

Thanks for fast shipping (received within 3 day). my solder iron will warm up soon
I think this board is a great value for migrating to TTN V.3 with the new and huge MCCI library (probably you update the documentation?)
on the schematic there is missing JL, and RST on the board is marked as JP1. that's what I've seen so far

A very good product. Exactly what I needed.

Not many things to say. The miniBrick is perfect for my project. I succeeded to send data over a not quite flat landscape with only one and half mW between 2 points at 25Km. The SMA plug for antenna is very effective for this purpose.

Great product!

For Powerful USB-to-Serial Adapter

Very nice product, good build quality. The perfect companion for all those projects that need just that bit of extra juice. Will buy an extra one just to have a spare around, cannot go without it anymore!

Perfect board for Lora Nodes

This board is truly low power and very efficient. Build quality is great.
I've been looking for a long time for a board like this.

João Pedro | March 7, 2021

Exactly what I needed

Just had a few RFM95 modules around for experiments, but without a proper breakout board is hard to prototype anything. These breakouts just work!

Michales / Parthena | Feb. 27, 2021

Perfection

I wanted this board for low power and extra flash to use MCCI LMIC. To my surprise 1284P has more pins than 32u4 / 328p and every pin is PCINT! Great for deep sleep projects that require multiple sources for wake-up.

To use with TinyLoRa use those pins (don't forget to solder RST)
`TinyLoRa lora = TinyLoRa(2, 4, 3); // IRQ, CS, RST`

To use the LED solder and add this line
`#define LED_BUILTIN PIN_PC5 // MegaBrick pin 21`

My cheap polymeter says 7μA with watchdog enabled. I didn't test power down. I suppose it will be lower as described.

A perfect buy. Thank you.

Only one suggestion. Maybe its' better to have a jumper for the LED to disable / enable at will?

Michales / Parthena | Feb. 24, 2021

It just works.

For Powerful USB-to-Serial Adapter

What more can I write: It just works. Great buy. I am newbie and inexperienced. It was easy for me. Works with linux if you enable the FTDI driver on linux kernel. Kernel Config: 'CONFIG_USB_SERIAL_FTDI_SIO=m'

A must have!

When working with rfm95w as hobbyist, you just need this breakout board if you want to make something that doesn't look messy!

To easily start in Low Power projects in LoRaWAN

Very satisfied with my purchase and the seller. Received in just a few days, well protected.
The PCB is well thought out, easy to weld and well labeled. At programming level, the instructions are sufficient for start a project without headache. The brief but complete documentation allows you to start a LoRaWAN project quickly.

Important if you use LMIC lib, add this line in the setup after the LMIC_reset:
LMIC_setClockError(MAX_CLOCK_ERROR * 20 / 100);
Cause the RX windows to open earlier to accommodated issues caused by the Arduino Mini's relatively slow (8 MHz) clock.

I carried out some tests and I realised it in Deep Sleep a current consumption of only 6.95uA.
I recommend this shop and this card to easily start in Low Power projects in LoRaWAN.

Perfect start for my new project

My current wireless low power projects involve HopeRF RFM69 and/or RFM95 modules combined with the ATMega328P processor as it is used on Arduino UNO, Arduino Nano or Arduino Pro-Mini boards. Unfortunately I ran out of flash and RAM using the ATMega328P. The solution is the megaBrick as it offers 4 times as much of flash. The ATMega1284P processor mounted on the megaBrick is supported by the Arduoino IDE and the the "MightyCore" library (https://github.com/MCUdude/MightyCore).
The megaBrick was delivered within 2 days and looks professionally built. The boards are a bit bigger than a Arduino Nano, have a 3.3V LDO, a placeholder for a RFM69HCW or a RFM95 RF module, and a 16MHz crystal. The bootloader is preinstalled. Installing the core library and programming the board is done within minutes. Very nice!
Since the ATMega1284 is another AVR, it is very easy to migrate from a ATMega328P based project. In most cases just the GPIO ports have to be adopted/renamed, and that's it. Almost all Arduino libraries support the megaBrick, the "LowPower" library is to mention here especially.
For advanced users who want to change fuse settings, the megaBrick does not have a ISP adapter. Fortunately the required GPIO's are available at the pin headers. So I took a little piece of prototype PCB and built my own adapter which I can now plug on top of the megaBrick - when needed.
Conclusion:
Very nice product, very nice support, good price/performance ratio.

Thank you so much :-) I am happy that you liked the board. Regarding ISP header, I am working on a baseboard that will also include a ISP header that might ease the job.

Great product

Only after tinkering with independent modules it becomes obvious why this little device is a great idea, especially for beginners. It has everything you need, and lets you concentrate on the project itself. The board quality is very good and it is easy to solder a dugtherboard module. Shipping is cheap and reliable, and communication with the seller is quick and informative.

Just what I needed a Atmel328 + Lora module

And it is in a small package. I would like a few more ground and 3.3 volt pin. They are always handy when hooking up external sensors.

S | Oct. 10, 2020

Just perfect.

For Powerful USB-to-Serial Adapter

A little more power on the 3.3 Volt setting is very nice. Especially when you powering Lora modules. With my old adapters I used to unexcepted reboots when sending packet with the Lora module.

Too good to disappear

I'm very pleased LPD/LPS are back again with this LoRaWAN development board. I was sad when the LoRaWAN Mini disappeared. I wanted to buy more but when it disappeared from Tindie I thought I would have to make my own... until I saw this updated version with more flash memory - great! To be honest the LoRaWAN Mini didn't have enough memory for both a LoRaWAN stack and an Adafruit soil sensor.

This megaBrick is professionally assembled to high quality with lead free solder (I don't like lead free for hobby use but lead free is the professional choice when you sell products). I would like to upload a photo but Tindie doesn't let me. It doesn't waste power on inefficient regulators or LEDs (unless you solder a link) so it can run for over a month on a 400mAh battery (with the 'LowPower' library), probably a lot longer with reduced transmissions (my tests sent a transmission every 10 minutes).

I wish LPS every success with this megaBrick and I hope it remains available for a long time. However in case it disappears soon, I recommend any purchaser to save/download the product page and schematic asap. Also a recommendation for LPS; the Tindie product page is good but doesn't print cleanly (Tindie website problem) so it would be helpful to have a downloadable PDF with the product specs, usage information and schematic.

Message to LPS: if you improve the technical documentation by making it downloadable (printing the Tindie page doesn't work) I will increase my documentation review from 4 to 5 stars.

Thanks

Response from Low Power Solutions | Nov. 14, 2020

Thank you so much for the great review, I appreciate :-). As per your feedback I have added the printable version (PDF) of the documentation which also includes schematic, please check product page.
Regarding your low power application. I am working on a base board for megaBrick which will include, apart from other useful things, an RTC that can be used as an external wake-up source. Using this, will allow going into deep sleep with RTC as a wake-up source.
