Our project centers around the innovative construction and programming of a versatile robot using the robust Pololu Romi Chassis Kit as its foundation. At the heart of our design is a custom carrier PCB, which integrates seamlessly with the chassis, ensuring a compact and efficient layout.

Key components of our build include two TB9051FTG Single Brushed DC Motor Driver Carriers for precise motion control, and a Pololu 5V, 2.5A Step-Down Voltage Regulator D24V22F5 to ensure stable power supply. Navigation and orientation are handled by the sophisticated MPU-9250 9DOF Module, a nine-axis…

Power control: common questions

What microcontroller does the Power control use?

The Power control is built around the ATTINY1604-SS, from the AVR/Arduino family.

How big is the Power control PCB?

The Power control measures 20.3 × 28.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power control?

23 components, from 14 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 Power control design files?

From the portlandrobotics/common_platform repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Power control design in my own project?

It is published under SHL-2.1, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Power control without the hardware?

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