It is possible to buy premade PCB’s with this chip, like Lora Radio Node v1.0, the documentation here. It is necesary an ISP programmer or arduino Bootloader.
In order to program it:
- Install Arduino IDEA
- Connect a FTDI232. The pinout is here. Connect the 6 cables.
- On arduino IDE select the board “Arduino Pro or Pro Mini”, and the processor “ATmega328P (3.3V, 8 MHz)”. On the microcontroller is already the bootloader of Pro Mini.
- Test the blink script and send some UART data.
Install libraries
Example send and receive data
- Download this repository
- Upload the code in one device, the transmitter, and the receiver in the other.
