From the project

KiCad schematic for Mbot Microcontroller

A high-performance embedded control board designed for autonomous mobile robotics.

The Astra Robotics Controller bridges the gap between prototyping boards and industrial PLCs. Built around the Raspberry Pi RP2040 microcontroller, it integrates high-current motor drivers, redundant sensing, and non-volatile "Black Box" data logging into a unified, vibration-resistant PCB.

MBotMCU: common questions

What microcontroller does the MBotMCU use?

The MBotMCU is built around the TPS565201DDCR, from the RP2040/RP2350 family.

How big is the MBotMCU PCB?

The MBotMCU measures 60 × 60 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MBotMCU?

122 components, from 53 distinct parts. The full bill of materials is listed on this page.

Where can I download the MBotMCU design files?

From the kartikvmlad/MBotMCU repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the MBotMCU design in my own project?

The repository has no license, so all rights stay with kartikvmlad. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MBotMCU 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.
