What is it?

Tiny ESP32-PICO-D4 based development board containing USB programming interface (CP2102), Lipo charger, and SSD1306 OLED display

Why did you make it?

Through conversation with buyers and youtube video viewers, I've noticed not all people need high-resolution audio DAC nor MEMS microphone. Some people want a simple tiny developing board that contains powerful ESP32-PICO-D4 (240MHz dual-core MCU) and USB-serial interface for programming and a Lipo charger and an OLED display. Indeed, I made one long time ago but simple reproduction is not my interest. This time I made the advanced one with an advanced chip (ESP32-PICO-D4).

What makes it special?

Tiny size, 25 x 36 mm
Even in tiny size, it contains USB programming interface, OLED display, Lipo charger
Not full but several GPIO pin-out are on-board.
With the fully-reconfigurable feature of ESP32, the pinout can work I2S, I2C (one bus occupied by OLED), SPI and more!
VERY GOOD PRICE
