USB Driver

Before programming, you need to connect a USB-TTL programmer to Stamp-Pico and connect according to the board's silkscreen. Install the corresponding driver for the programmer on your PC.

The most convenient way is to purchase the Stamp-Pico kit with a programmer . The included programmer's pinout matches Stamp-Pico, allowing direct plug-and-play programming without wiring. M5 currently offers two versions of programmer drivers: CP210X (for CP2104 version) and CH9102 (for CH9102 version). After extracting the driver package, select the installation package corresponding to your operating system. (If you are unsure which USB chip your device uses, you can install both drivers.)
