This project is an open source USB 433Mhz rf transmitter / receiver based on an atmega328p. It can be used to control ac rf switches running on 433MHz.
Why did you make it?
Because I used a raspberry, I could use the rpi_rf component in home assistant. That was working fine until I needed more computing power, so I switched to a desktop computer and couldn't control some devices anymore (like my rf switches). Because of this, I started to develop this board and a custom integration in-home assistant.
The integration into home assistant still has some bugs but should be working well enough.
What makes it special?
Although I ship it with the open433 firmware pre-installed to be compatible with my library (and home assistant), it has the Arduino UNO bootloader and can be programmed as a classic Arduino.
It also has an expansion port under the board for SDA/SCL/A0/Pin8.
