Neoprogrammer 21 019 Ch341a Best Info

The CH341A is a mass-produced, often blue-colored PCB featuring a chip by WCH (Nanjing Qinheng Microelectronics). Originally designed as a USB-to-UART/I2C/SPI bridge, it was never intended to be a high-voltage parallel programmer. Yet, the community discovered that with a simple 5V-to-3.3V level shifter, it could speak to common SPI NOR flashes (like Winbond 25Q series) perfectly well.

CH341A Black Edition (USB 2.0, CP2102 or genuine WCH chip) – sold with a SOP8 test clip and 1.8V adapter board. neoprogrammer 21 019 ch341a best
