Here my version

ESP + LED DRIVER + 1.8v + 3.3v, plus I2C 1.8v->3.3v->1.8v plus battery managment. + RFID + RG Leds + FTDI + wifi antenna + Pedometer

Next version will be 30 % smaller.

Not sure you have seen the "new ESP32-PICO Q7" on the "Small" ESP Modul, the ESP32-PICO Q7 is a new ESP32 with all include in the SoC Package, OSC and Flash is include too. it is a miniature ESP32 modul in a package.

if you can use in your next PCB that is 30% smaller you can save again place cause you did not need OSC and Flash example.

this was a prework of the ESP32-PICO Q7
