Product Description
===================

Inside 25 x 36 mm square, it contains USB-serial, ESP32, LiPo charger, and
OLED display!


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 (240 MHz
dual-core MCU) and USB-serial interface for programming and a LiPo charger and
an OLED display. Indeed, I made one long time ago[1] 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,
  and 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

• Arduino sample code is available at GitHub:
