Overview
HRPM IR Array is an open-source printed circuit board by Aahil78, from the Aahil78/HRPM repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 160 × 25.7 mm with 67 parts on 42 nets, routed with 657 tracks and 103 vias.
It is built around the RC0603FR-0710KL and TCRT5000L. Its parts include 40 resistors, 2 capacitors and 1 connector.

README.mdHRPM - A High Speed PID Based Line Follower
A very fast Line Following Robot with a cusom IR Array and control PCB, uses PID Based algorithim.
Features:
- High Speed for fast track completion
- Custom 20 Sensor IR Array Module for precision
- Integrated MCU, Motor Driver, and LiPo System (Charger Seperate) For good control and OTA PID Tuning -- COMING SOON
- Custom 3D Printed Chassis for modularity. -- COMING SOON
- More to come soon!
Why I made this:
I made this because I go to comps often and many times I lose, I've noticed that many bots aren't fast so I decided; what if I make a high speed LFR, that'll help me win comps and get some prizes and network around with people.

Questions
How big is the HRPM IR Array PCB?
It measures 160 × 25.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HRPM IR Array use?
67 parts, built around the RC0603FR-0710KL and TCRT5000L. 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 HRPM IR Array KiCad files?
From the Aahil78/HRPM repository on GitHub, at the commit this page was made from: the board is IR Array/src/HRPM_IR_Array.kicad_pcb and its schematic IR Array Reciever/src/IR_Array_Reciever.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HRPM IR Array design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
