Stamp-Pico
SKU:C050-B
Description
Stamp-Pico is a plug-and-play, cost-effective Wi-Fi minimum core board. Powered by the Espressif ESP32 SoC, it is equipped with two low-power Xtensa® 32-bit LX6 microprocessors running at up to 240 MHz. With its compact size, high performance and low power consumption, it is ideal for space-constrained or battery-powered IoT applications.

Download Program
Stamp-Pico adopts an ultra-simplified circuit design and therefore does not include an onboard download circuit. To burn firmware, connect a USB-TTL downloader as shown below.

USB Driver
Before flashing, you need to connect a USB-TTL downloader board to the Stamp-Pico according to the silkscreen. Install the corresponding driver for the downloader on your PC.
For the easiest experience, purchase the Stamp-Pico kit with downloader. The cable order is identical to STAMP-PICO, allowing direct plug-in flashing without wiring. M5 currently provides downloaders with two driver chips: CP210X (for CP2104) / CH9102 (for CH9102). After extracting the package, choose the installer matching your OS bitness. (If you are unsure which USB chip your device uses, install both drivers.)
