Stamp-Pico DIY Kit

SKU:K051-B

Description

Stamp-Pico DIY Kit is a development kit for the Stamp-Pico minimum core board. The kit includes the Stamp-Pico, as well as female headers, male headers, an HY2.0-4P female socket, and an ESP32 Downloader. The pin sequence of the ESP32 Downloader is the same as that of the serial port download pins on the Stamp-Pico. You can directly insert it into the pad holes to burn the program.

The Stamp-Pico is a high-cost-performance Wi-Fi minimum core board. This module uses the ESP32 main control chip. The chip is equipped with 2 low-power Xtensa® 32-bit LX6 microprocessors, and its main frequency can reach up to 240 MHz.

The Stamp-Pico is characterized by its small and compact size and excellent performance. It can be very conveniently embedded into your application circuit to build IoT applications.

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.)
