World’s Smallest ESP32

This is the smallest ESP32 in the world (10x10x10mm), fully functional without the need for additional electronics for programming or usage 😁

Every electronic component of the device is inside it's own PCB (except buttons).

It have 6 PCBs on top of each other, each one with 4 layers, a total of 24 layers 😁

It have:

  • Micro USB
  • DC-DC converter with current capacity up to 1A
  • FTDI chip for USB-UART conversion
  • ESP32 Pico D4 mcu
  • 2 buttons
  • 2.2 dbi antenna for WIFI and bluetooth
  • A fewmore electronics like capacitors, resistors and coils
  • 18 pads for GPIO / Power
  • 8 of which have 2.54mm spacing that can be used for solder headers for direct breadboard usage

The quality of the Wifi signal is exactly the same as the ESP32-WROVER-IE (in the picture), which is impressive!
