Arduino homemade Ledi receiver voltage return module

Overview

Self-made Radio receiver OSD return module based on Arduino. Because the LED backhaul module and receiver are two independent modules, they take up space in drones or other small models and add unnecessary wiring. Most importantly, it's expensive. I learned that the Radi receiver and OSD backhaul module use I2C communication. After some netizens on the Internet used a logic analyzer to analyze their communication methods, I used an Arduino development board to verify it. The result is feasible~~The ADC data is accurate and stable after being processed by the anti-pulse interference average filtering method. So now I draw a PCB myself and integrate the OSD backhaul module into the Radix R9DS module.
