IoT Switch Prototype DFPlayer Mini

Another great job from the PCBWay team. High quality and fast turnaround. This is a stepping stone to a larger project. It has a XIAO-ESP32-C6 MCU, a DFPlayer Mini, a switchable choice of speaker or ear phones o/p, 4 buttons, 3 user and 1 connected to the MCU boot i/p which is otherwise really fiddly to use. Also a normal LED and a programmable RBG LED. This PCB is also a proof of design of my XIAO-ESP32-C6 custom PCB footprint giving access to the surface mount i/o connections on the bottom side of the MCU using conventional soldering techniques. No need for SMD techniques. It worked perfectly.
