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

From childhood, I've loved making electrical things by soldering for some amateur radio related thing.
After graduated certain university and taking Ph. D, I did have a GaAs MMIC design working for 60 GHz system
but it's a bit long time ago.
I always love making something and would like to share my joy. Please enjoy my store!
