Mike here, from Australia. We've been doing some hardware development for some time now and decided to include a LoRa board, which has been just release and might interest you:

Whisper Node AVR - LoRa

A real ultra-low power LoRa development board based on the popular Atmel AVR ATMega328p - Arduino compatible. Thanks to the highly efficient MCP16251 Step-up Switching regulator, this board can be powered with little as 0.9V. In other words, you can run it on a single Alkaline Cell until the battery is totally dry.

Alternatively you could connect a 5V power supply, like an USB charger, and take advantage of the ultra-low quiescent current MCP1700 LDO regulator, capable of 250mA, providing more flexibility while developing or running hunger projects. The board also counts with a smart voltage monitor, which will automatically switch from a power supply to the battery in case of power-loss or vice-versa. Alternatively you could use a Li-Po cell and the board will decide to use the LDO or the Step-up regulator based on the cell voltage to maximize the running time on a single charge.

As standard, this board comes with a RFM95/96 LoRa Radio (Semtech SX1276), giving you long-range wireless connectivity out of the box! Finally a W25X40CL 4MBit SPI Flash is attached to the PCB, giving you plenty of storage and option for remote firmware upgrade over-the-air. You get all this running on a board that consumes around 6µA in sleep mode when powered by a 3V source, like two Alkaline cells.

The Whisper Node board is shipped with all headers (un-soldered) and external 2dBi (± 0.7 dBi) PCB antenna with a u.FL connector, matching the radio frequency. The small PCB antenna provides an excellent balance between performance and size.

Additionally the board can be easily upgraded to fit a SMA antenna connector, a temperature compensated real-time clock, a CR2032 battery holder or a high-capacity LDO, making the board a ideal as a low-power remote node or as a powerful base station.

The documentation and examples should be release soon, but I believe most of you in the forum don't really need that :wink: - If you need it now, you can check the RFM69 documentation version, which would be very similar (

Hi wisen,

very interesting product... is in your plans a version with RN2483? since, if I'm not wrong, RFM95 is not LoRa-Alliance certified?



very nice with that extra flash memory :sunglasses:

we are group of software and hardware develops from Ukraine, Kharkov and we would like to introduce our board Lothings A3
that is based on on RN2483 + HC08(HC06). According to our plans it could be used as a router to forward messages from bluetooth network to LoraWAN and vise versa.
Also it has the following features:
-setup parameters of sending(power,SF,Ack flag,up/down message counter,port)
-send messages

For convenience purposes all this action could be done by using Android application that has the following features:
-set/get the current power,SF,Ack flag
-set/get the current up/down message counter
-set/get the current DevAdr, AppSKey, NetSKey for ABP mode
-set/get the current DevEui, AppKey, AppEui for OTA mode
-send message to specific port(user input or gps data of phone),messages could be sent by press button event or timer
-update current version of firmware( user even could change code for instance to use free pins of board for his purposes )
-connect to board Lothings A3 through bluetooth channel
-connect to server mqtt bus and get RSSI,SNR of messages that were received by gateway
-for messages with Ack = true show the client value of RSSI,SNR

Also the board could be used for testing the parameters of transmitting/receiving messages form client/server side and as the result to estimate the quality of covering your LoraWAN.

You're right, RFM95 is not LoRa-Alliance certified, but we don't have plans produce a Whisper Node using the RN2483 on the public boards.

What I can share is that we're developing a STM32 version with low-power in mind as well. We still investigating which ST MCU offers the better cost/benefits and still able to run at very low-voltage to use with normal Alkaline cells.


Hi Everyone. Some very cool and interesting designs / products posted here. Thought I would add mine too.

Going into this, the aim was to create a key-ring sized device capable of mods to suite the needs for any application including GPS tracking and some other features. Soldering on the first batch was done manually, so please do excuse it.

Some of the features:

  1. GPS Tracking (optional)
  2. Movement detection and activity monitoring
  3. On-board temperature sensor
  4. Expansible IO through SPI bus
  5. Header for additional analog sensor
  6. Built-in Bluetooth LE central stack
  7. Solar / Battery or hybrid operation
  8. Integrated and configurable charge circuit for Li-Ion
  9. Based on the awesome RM1xx
  10. Programming header for the code freaks
  11. Programmable user button.
  12. Antenna can either be external or mounted on-board depending on the application.
  13. Uses less than 10 uA when in sleep mode.

Device operation time with all the bells and whistles enabled running on a 600mAh battery, exceeds 10 hours when transmitting every 45 seconds.

I was about too, but 35 euros postage? that'c crazy - plus tax


I am offering this RN2483 Raspberry Pi Zero Hat on Tindie.
There is an special discount code for TTN forum users.

Hi professional TTN users in the EU.

EBV will sell the Laird RG186 Gateway starting at the end of this month for € 245,- excl. VAT and shipping cost.

Please contact me or your local EBV office for more details. or

We only sell to business customers unfortunately.


Item pricing for the lorawan accelerometer will be adjusted, postage will be reduced and tax will be removed. Total price incl shipping would be 69+15 = 84€.
Please send a mail to when still interested!

What kind of MSRP can we expect? Just a rough estimation.
