KAPico

Description

KAPico is a miniature board with RP2040 microcontroller from Raspberry. The board is equipped with 16MB of Flash memory (compared to 2MB of memory on the Raspberry Pi Pico board), connectors with a pitch of 2.54mm allowing for easy attachment of the module to breadboards or universal plates. Thanks to its small dimensions, the product can be used in many development projects.

Built-in RGB LED

The KAPico module is equipped with a three-color LED diode, which is controlled by the microcontroller terminals that are not connected to the connectors.

BOOT and RST buttons

The KAPico module is equipped with two buttons that facilitate programming of the RP2040 microcontroller. Thanks to the RST button, the user does not have to disconnect and connect the USB cable to reset the microcontroller, while the BOOT button performs the same function as in the Raspberry Pi Pico - it starts the bootloader which allows its programming.
