Fermion: ADKey Board -10 Keys (Breakout)

A 10-key AD keypad can easily drive the DFPlayer PRO, DFPlayer Mini, andvoice recording module eliminating the need to use a microcontroller to handle control logic, thus reducing project complexity. The 10-key AD keypad can serve as the AD keypad input for the development board, expanding to 10 keys with just one analog port, significantly saving on the development board's I/O resources. Additionally, by connecting other keys through the solder pads on both sides, it can adapt to various project structures.
