Now officially named the PicoGAME SPGA.
Several changes have taken place:
the AUX pin on the GPIO port now has an internal link and can be connected to GP30, +5 or 3V3.
3V3 to the GPIO port is now from a linear regulator, not the Pico which uses its switcher. The reg also powers the ESP8266-01S and the front panel LED connector.
Three different options for the SD card. Two different full size sockets or the "inverted" micro SD module that doesn't require SMD soldering.
The RTC battery can now be either CR1220 or CP2032.
A SMD LM4040-3V can optionally be fitted. There is a link to disconnect it.
I've almost finished designing front & rear PCB panels for the box.
The circuit diagram is almost finished and I'm on with the manual.
Now I have a conundrum.
Which to fit? ESP8266-01S or HC-05? I rather fancy the idea of the latter because no-one has done it yet AFAIK but it might be of less use than a router connection. Unfortunately there isn't enough PCB area to fit both.
