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
- ESP32 GOLD EDITION BOARD Powered by the ESP32-WROOM-32E module with dual-core 240MHz Xtensa LX6 CPU, 4MB flash, WiFi 802.11 b/g/n, and Bluetooth (Classic + BLE). Lead-free ENIG (Electroless Nickel Immersion Gold) finish for good oxidation resistance and conductivity.
- PinPulse Shield for Easy GPIO Access Features 2.54mm male and female pins on each GPIO to fit any jumper wire type directly — convenient connections for prototyping with Dupont wires and breadboards.
- Visual GPIO Indicators Each GPIO pin includes an LED driven via high-impedance logic ICs, displaying HIGH/LOW states in real-time without disrupting operation or SPI/I2C protocols — suitable for beginners and debugging.
- Plug-and-Play Display Connector Dedicated FPC port for attachment to Lonely Binary displays (TFT LCDs, E-Ink, touch screens) via a single ribbon cable — no jumper wires needed. (Displays sold separatel... Read More...
