Description

The M5Stamp Pico Mate is a compact accessory and development kit for the Stamp-Pico minimum core board. It includes the Stamp-Pico module, matching male and female headers, a HY2.0-4P female socket, a high-temperature sticker, and a hex key, giving the M5Stamp Pico Mate the practical hardware needed for quick embedded integration.

Powered by the ESP32-PICO-D4 module, this Wi-Fi minimum core board provides dual Xtensa 32-bit LX6 processors up to 240 MHz, 4MB flash, 520KB SRAM, and 2.4 GHz Wi-Fi. The ESP32-PICO-D4 module keeps the M5Stamp Pico Mate small enough for custom boards while still supporting connected sensors, device control, and compact IoT products.

As a pin header kit, the package supports soldered, socketed, and cable-based builds. Developers can use the pin header kit to expose GPIO, power, and serial signals, then place the M5Stamp Pico Mate into smart home, wearable, medical, or other space-limited applications.

Features

• ESP32-PICO-D4 module: dual-core ESP32-PICO-D4 processor, 4MB flash, 520KB SRAM, and 2.4 GHz Wi-Fi.
• Pin header kit format: the pin header kit includes 2.54mm male and female headers for flexible prototyping.
• Multiple mounting methods: the M5Stamp Pico Mate supports SMT, DIP, flying lead, Grove socket, and outer-shell integration.
• Compact protected shell: high-temperature plastic armor protects the 3D antenna and board components.
• Built-in feedback: one programmable RGB LED and one programmable button support setup, status, and test functions.
• Development platforms: UiFlow1, UiFlow2, Arduino IDE, ESP-IDF, and PlatformIO are supported.

Embedded Hardware Fit

The ESP32-PICO-D4 module gives this board a very small footprint, and the included pin header kit helps developers choose the right physical connection method for each prototype or small production board.

Specifications

Applications

• Smart home nodes: use the M5Stamp Pico Mate for compact Wi-Fi sensors, switches, small controllers, and appliance control boards.
• Wearable devices: the ESP32-PICO-D4 module supports small wireless products that need processing power in a low-profile board.
• Medical equipment prototypes: the board can support compact monitoring, data collection, and portable connected-device prototypes.
• Custom PCBs: the pin header kit helps expose power, GPIO, serial, and control signals during small-run hardware design.
• Education and prototyping: the M5Stamp Pico Mate works well for learning ESP32 development with Arduino, UiFlow, and ESP-IDF.

Connection Planning

The included pin header kit gives you both 9P and 6P header options, plus a HY2.0-4P female socket. This makes the M5Stamp Pico Mate useful when a project needs repeatable bench access before moving to a soldered custom board. For small production runs, the pin header kit also helps keep early wiring choices flexible.

Pin and Circuit Reference

The ESP32-PICO-D4 module exposes 12 GPIO pins including G0, G1, G3, G18, G19, G21, G22, G25, G26, G32, G33, and G36. Review the pin map and schematic before assigning ADC, I2C, UART, RGB LED, button, or sensor functions.

Mechanical Reference

The 24.0 x 18.0 x 4.6mm module size helps the M5Stamp Pico Mate fit inside small housings, embedded controllers, and custom PCB projects.

FAQ

What is included with this kit?

The M5Stamp Pico Mate includes Stamp-Pico, two male headers, two female headers, one high-temperature sticker, one HY2.0-4P female socket, and one L-shape hex key.

Does this package include an ESP32 downloader?

No. This pin header kit does not include an ESP32 downloader. Choose the DIY Kit version when a downloader is required in the box; choose this pin header kit when headers and socket accessories are the priority.

Which controller does the board use?

It uses the ESP32-PICO-D4 module, which integrates ESP32, flash, crystal, filter capacitors, and RF matching components in a compact package.

Can the M5Stamp Pico Mate be used with Arduino?

Yes. The M5Stamp Pico Mate supports Arduino IDE as well as UiFlow1, UiFlow2, ESP-IDF, and PlatformIO.

Is the official video in the media gallery?

No. The official video is embedded after the Description section, while the media gallery remains image-only.
