LoRA Node models

LoRA Node modules

After doing some experiments with a few DIY nodes I started to use different models desigend by people who create way more fancier PCB's then I do.

Here's a list of node designs I really like.

 

TVB-Lorawan-node

On the webpage from Thomas van Bellegem (Belgium) he designed a new LoRaWAN node with a Atmega1284P processor on board and the possibility to support a RN2483 or a RFM9x module.

Node images, drawing and specs (c) Thomas van Bellegem.

Microcontroller	Atmel Atmega1284P (Arduino compatible, incl. bootloader & library)
Size	40 x 25 mm
Operating voltage	3.3V (onboard regulator)
I/O pins	24 available pins (Digital I/O, Analog input, PWM, UART, SPI & I2C)
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 speed	8 MHz
Power	5V USB power 3.7V LiPo battery
Charging	Solar charge controller with status LED, up to 500mA charge current (max. 6V input)
LED	RGB LED + extra blue LED
LoRaWAN	HopeRF RFM9X Microchip RN2483 / RN2903 (High-band only)
Antenna	U.FL and/or SMA connector
Programming	FTDI programming header
Extra	Default JST battery connector Buid-in battery voltage measurement Onboard reset switch Breadboard compatible headers

After exchanging a few e-mails with Q&A, I ordered 2 nodes, one with the RN2483 and one with a RFM95W on it. The posibility for the proto shields gives me good opertunities to experiment with them.

One of the things I build with this node is a TTN GPS tracker which can be found at LoRA GPS Tracker

 

CH2I Arduino-Mini Node

TheThingsNetwork user Charles Hallard has a create Arduino Mini Pro LoRaWAN Node PCB design on github to make a small compact sensor. Checkout his GitHub page : https://github.com/hallard/Mini-LoRa

I have orded a batch of them for my LoRA environmental node.

Update : With version 1.1 he has released the design files.
