README
README.mdProject A.L.I.E.N. Main Board
This is the repository for the main board of Project A.L.I.E.N. (Autonomous Labyrinth Investigator, Explorer, Navigator).
This project started as a University project for the module Robotics Design and Construction. To get us started, the University provided us with a main board, called the ARB (Arduino Robotics Board), which was designed to break out the pins of an Arduino Nano 33 BLE into connectors that were easier to use. However, when the module concluded, the University wanted the boards back, so I designed my own.
Testing
The code to test the board has been split into separate repositories.
- Motors and Encoders
- Bumper and NES Shift Registers
- LED Strip and Level Shifter
- Ultrasonic Sensor
- Infrared Sensors and I2C Multiplexer
Expansion Boards
The Project A.L.I.E.N. Main Board has been designed to to take expansion boards. This utilises the 3 left-over GPIO pins, D11, D12 and D13.

Questions
How big is the Project alien main board PCB?
It measures 69.1 × 100.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project alien main board use?
53 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Project alien main board KiCad files?
From the HBoyd255/project-alien-main-board repository on GitHub, at the commit this page was made from: the board is hardware/ProjectALIENMainBoard.kicad_pcb and its schematic hardware/ProjectALIENMainBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project alien main board design in my own project?
Its repository states no licence, so its author keeps all rights: ask HBoyd255 before reusing the design.
