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

Downloading the Program
- The Stamp-Pico adopts the most streamlined circuit design, so it does not include a program download circuit. When using it, users can download the program through a USB-TTL programmer. The wiring method is shown in the figure below.
The shell supports the reflow soldering temperature curve.

USB Driver
Before performing the burning process, you need to connect a USB-TTL programming board to the Stamp-Pico and make the connections according to the silkscreen on the board. Install the corresponding driver for the programming board on the PC.
The most convenient way is to
purchase the Stamp-Pico kit version with a programmer
. The wire sequence of the included programmer is consistent with that of the STAMP-PICO, so you can directly plug it in for burning without wiring. Currently, M5 offers programmers with two types of driver chips, and there are compressed packages of driver programs for CP210X (suitable for the CP2104 version)/CH9102 (suitable for the CH9102 version). After decompressing the compressed package, select the installation package corresponding to the bit number of your operating system for installation. (If you are not sure which USB chip your device uses, you can install both drivers simultaneously.)
