Overview

Product Overview

The CH341A is the standard low-cost programmer for serial memory: a WCH CH341A USB 2.0 bridge that speaks SPI, I2C and UART. It reads, writes, erases and verifies 25-series SPI flash (W25Q, MX25, GD25, EN25, S25FL and compatibles up to 128 Mbit / 16 MB) and 24-series I2C EEPROMs (24C01–24C512). Chips drop into the 16-pin ZIF socket, marked for 25XX and 24XX parts, or you clip onto a soldered SOIC-8 through the SPI header for in-circuit work.

On Windows use AsProgrammer or NeoProgrammer; on Linux and Raspberry Pi, flashrom or IMSProg. An AMS1117 3.3 V regulator, a 3.3 V / 5 V power header, power and activity LEDs and a 12 MHz crystal are onboard. For BIOS recovery, router and set-top-box firmware backups, and reprogramming EEPROMs on embedded boards.
