RobotHat: common questions

What microcontroller does the RobotHat use?

The RobotHat is built around the C14877, from the AVR/Arduino family.

How big is the RobotHat PCB?

The RobotHat measures 65 × 63.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RobotHat?

40 components, from 36 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 RobotHat design files?

From the aliaafee/robot-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 RobotHat design in my own project?

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

Can I test firmware for the RobotHat 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.
