I used 2x ESP32 (instead of only 1 in #Xts-uBASIC Pocket V2 ) because I needed hudge RAM to correctly manage the 320x240px Screen ops. (& ESP32 is relatively cheap & fast) so there is an UART Bridge between BOTH MCUs in order to send commands from #1 (BASIC+BEEP+BTNs+WIFI) & #2 (SCREEN + MP3Player) Then the SX1509 boards allows me to read all buttons to #1...Dual ESP32 layout explained
