The CH34X family comprises widely used USB‑to‑serial chips manufactured by WCH (WinChipHead), commonly integrated into generic UNO R3, ESP8266, and ESP32 development boards.
Overview
This is an I2C, 512Kbit, Serial Electrically Erasable PROM (EEPROM), capable of operation across a 2.5V to 5.5V range. It has been developed for advanced, low-power applications such as personal communications or data acquisition. These 8-pin chips can be the back bone of any microprocessor project, only need two wires to communicate, and retain their data even with power failure.
