The Raspberry Pi Host Function Tester Pico is a conversion board that allows you to use a Raspberry Pi Pico as an existing Raspberry Pi.

The Raspberry Pi Pico is equipped with a microcontroller RP2040 and can be written in programming languages ​​such as Arduino, C/C++, and MicroPython.

By using this product, you can use the RP2040 to act as a tester for your homemade Raspberry Pi HAT.

Furthermore, the RP2040 acts as a host and drives existing HATs, enabling stable operation without the intervention of an OS, thereby improving the stability and reliability of industrial Raspberry Pi equipment.

Information such as sample software that runs our Raspberry Pi HAT products is currently available on Github.

This is an expansion board that allows you to start prototyping right away.

Two types are available: Pico mounted and unmounted boards.

Product application examples

・ Tester for homemade Raspberry Pi HAT

・ Stabilization of industrial Raspberry Pi equipment

・Improved scalability of Raspberry Pi Pico

・Prototyping applications

Converting an existing Raspberry Pi HAT for use with the Pico

・Connection and control of IoT devices and sensors

Product Features

・Can connect Raspberry Pi Pico and Raspberry Pi HAT

It is possible to connect an existing Raspberry Pi HAT to Raspberry Pi Pico.

You can use existing HATs as alternative testers for Raspberry Pi using newly supported programming languages ​​such as Arduino, C/C++, and MicroPython.

Improved performance and reliability for industrial applications thanks to stable operation without OS intervention by the RP2040

The RP2040 allows devices to operate without going through an OS.

It is expected to operate more stably than the existing Raspberry Pi.

- Fits in the official Raspberry Pi 4 case

The board size fits perfectly into the official Raspberry Pi 4 case, allowing you to use your existing HAT as is.

It can be used as a direct replacement for your existing Raspberry Pi.
