What is it?

This module is a small prototyping board. This LORA node is based around an STM32 "Blue chip" board using the STM32F103C8T6 and also an SX1276 - RFM95/96/97 LORA transceiver. It has an area for prototyping with pads ! and an input supply circuit to charge a 1 cell lipo and monitor its voltage via a resistor divider on board.

Why did you make it?

I am building a small LORA network with sensors and needed a baseboard to start with!

What makes it special?

The board uses a 32 Bit ARM Cortex processor. The main advantages are:

• Much more space for your program (most boards have 128K flash even when advertised as 64K)

• 20K RAM

• High speed 32 bit ARM Cortex-M3 processor up to 72Mhz

What is Included

I am ready to supply an assembled board with or without sample code preloaded . Or the bare PCB for who wish to build it on his own!
