Stamp-Pico
SKU:C050-B
Description
Stamp-Pico is a plug-and-play, cost-effective Wi-Fi minimal core board. It uses the Espressif ESP32 main control chip, equipped with 2 low-power Xtensa® 32-bit LX6 microprocessors, with a main frequency of up to 240MHz. It features compact size, strong performance, and low power consumption, making it suitable for any IoT applications with limited space or battery-powered scenarios.

USB Driver
Before programming, you need to connect a USB-TTL programmer to Stamp-Pico and connect according to the board's silk screen. Install the corresponding driver for the programmer on your PC.
The most convenient way is to purchase the Stamp-Pico with a programmer kit. The included programmer's pinout is consistent with STAMP-PICO, allowing direct plug-and-play programming without wiring. Currently, M5 provides two versions of programmer drivers, CP210X (for CP2104 version)/CH9102 (for CH9102 version) driver packages. After extracting the package, select the installation package corresponding to your operating system's bit version. (If you are unsure which USB chip your device uses, you can install both drivers.)
