ChessRobotArm: common questions

What microcontroller does the ChessRobotArm use?

The ChessRobotArm is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How big is the ChessRobotArm PCB?

The ChessRobotArm measures 40.3 × 82.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ChessRobotArm?

12 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the ChessRobotArm design files?

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

Can I use the ChessRobotArm design in my own project?

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

Can I test firmware for the ChessRobotArm 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.
