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
- UNPLUG USB. CODE KEEPS RUNNING. A dedicated power-path circuit runs the board from USB while the battery charges, then hands over to the battery the instant USB-C is removed - without the voltage dip that resets most charger boards. No reboot, no reset, no gap in your program. Built into the board itself, so it works with or without a shield.
- 3x ESP32 BOARDS — 6 HEADER STRIPS INCLUDED, UNSOLDERED Six header strips ship in the box; you solder them onto the 3 boards before use. The 3 shields arrive fully assembled and need no soldering at all. Each board: dual-core ESP32, 4MB Flash, Wi-Fi 2.4GHz and Bluetooth, USB Type-C for power and programming (CH340 serial), and a 500mA LiPo charger.
- 3 SHIELDS, 3 WAYS TO WIRE One of each, by design: 2.54mm pin header for fast jumper changes, spring terminal for tool-free rewiring, and screw terminal for the most secure, vibration-resistant hold. All three shields arri... Read More...
