About the CTRL-AI-Macropad PCB

CTRL-AI-Macropad is an open source RP2040/RP2350 PCB design by RishabhMewada, published on GitHub under the MIT license. It is a 2-layer board measuring 96.3 × 68.8 mm, with 22 components from 11 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. Other key parts include the MDBT50Q-1MV2, MCP73831-2-OT, MPU-6050 and AP2112K-3.3. By type, the board carries 7 switches, 7 diodes, 4 ICs, 3 connectors and 1 module.

It belongs with the keyboards, iot & wireless and displays & leds designs in this gallery.

From the project

An open-source AI-integrated macropad built with a Raspberry Pi Pico, featuring a mechanical key matrix, rotary encoder, and IPS display. Designed as a programmable control surface with future support for software-based key remapping and AI workflows.

Originally developed as a programmable macropad, the project has evolved into a battery-powered, dual-transport embedded platform built around the Raspberry Pi Pico (RP2040), featuring modular firmware architecture and wireless expansion capabilities.CTRL is a custom-built Human-Computer Interaction (HCI) Development Board designed for productivity tooling, embedded experimentation, wireless HID systems, and future AI-assisted workflows.

CTRL-AI-Macropad: common questions

What microcontroller does the CTRL-AI-Macropad use?

The CTRL-AI-Macropad is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the CTRL-AI-Macropad PCB?

The CTRL-AI-Macropad measures 96.3 × 68.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CTRL-AI-Macropad?

22 components, from 11 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the CTRL-AI-Macropad design files?

From the RishabhMewada/CTRL-AI-Macropad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the CTRL-AI-Macropad design in my own project?

Yes, under the terms of its MIT license, which RishabhMewada chose for the repository.

Can I test firmware for the CTRL-AI-Macropad without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
