ELRS 2.4_GEMINI_500mw

Overview

Using esp32 module, it is too difficult to solder without pico d4. The resistors and capacitors are all 0603, so soldering is very easy.
There is an onboard typec automatic download circuit. If you use the backpack function, short-circuit the two resistor pads R3R4.
Since the backpack uses the esp32 tx and rx ports, you cannot use typec to download the esp32 after soldering the backpack. You can add a DIP switch to solve the problem.
The board has been verified. Because of the lazy automatic wiring, let’s use the pcb as a reference. Many places can be optimized.
