22  (X) mandatory pins to connect for the minimum set-up
23  (O) optional connections for audio and I2C keyboard support

25  The keys (all) are using internal pullup so just connect the other side to the GND
26  I2C SDA,SCL, USER1 and USER2 requires external pullup (2.7k)
27  The Analog joypad also needs VCC and GND connections !
28  The Display part of the ILI: SDI,SDO,SCK,CS but also DC,VCC and GND must be connected
29  The i2ckeyboard : I2C SCL, I2C SDA, VCC and GND

31  Everything is powered over the USB connector of the ESP32!
