The TvB LoRaWAN Node is a LoRaWAN development board with powerful, Arduino compatible Atmega1284P microcontroller. The compact 41x26 mm, breadboard compatibel design makes it the perfect starting base for your all your LoRa (WAN) projects.
Microcontroller: Atmel Atmega1284P-AU (Arduino compatible)
Size: 41 x 26 mm
Operating voltage: 3.3V (fixed LDO regulator)
I/O pins: 24 available pins (Digital I/O, Analog input, PWM, UART, SPI, I2C & Interrupts)
Serial ports: 2x hardware serial, extended with SoftwareSerial library
Flash memory: 128 KB (4x more than Arduino Uno)
SRAM: 16 KB (8x more than Arduino Uno)
EEPROM: 4 KB (4x more than Arduino Uno)
Clock: 8 MHz
LED: Dimmable RGB LED + single blue LED
Antenna: U.FL and/or SMA connector, or a simple copper wire as antenna
Arduino library with starters examples for Arduino IDE 1.6.8 and up (Windows / OSX)
5 pin programming header for USB to Serial converter (individual dupont jumper cables are recommended for easy programming)
The board can be powered by:
External voltage on VIN pin (Max 6V DC input!)
External voltage on 3,3V pin (for example 2x AA or AAA batteries, never more than 3,3V!)
Single cell 3.7V LiPo battery on battery connector
3,3V or 5V USB-Serial converter
A 3,7V Li-Ion or LiPo can be connected to the decicated JST 2.0 PH battery connector. The battery can be charged by connecting a 5V USB-Serial converter or with a voltage above 3,7V (to maximum 6V) DC on the VIN pin using an external voltage or solar panel.
Charging the battery: orange status LED
Charging: Orange LED on (up to 500mA charge current with max. 6V input)
Charged: Orange LED blinking (trickle charge)
Not charging: Orange LED off
Build-in voltage divider for measuring battery state
Onboard reset switch
Breadboard compatible headers
Low power functions available (35uA in deep sleep using external LowPower library)
The Node supports multiple LoRaWAN transceivers.
HopeRF: RFM95W [433, 868 & 915 MHz]
Microchip: RN2483 (RN2483A) / RN2903 (RN2903A) [868 & 915 MHz, high-bands only]
The default version is shipped without LoRaWAN transceiver. You need to solder your own transceiver. You need some moderate soldering skills to do this without issue's. Fully assembled versions are also available when in-stock.
All orders include:
Male headers (not soldered on by default)
SMA antennaconnector (not soldered on by default)
Arduino library with examples
Digital users manual (English)
All boards are manufactured and tested in Belgium. Shipping in sealed antistatic bags, protected against ESD and moisture.

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.
We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
I'm Thomas, 23 years old from Belgium.
Electronics, software & prototyping are some of my hobbies and also my full time job.
I like to professionally develop & create things and Tindie is great to share them!
At the moment fully into Internet of Things (IoT), automation systems (domotica) and low power, wireless electronics.
In my store you can find what I have available.
I only have a couple of pcs in stock to prevent overstock. If your interested in higher volumes, let me know, I'll make them as soon as possible for you!
