From the project
ICRS PCB ruler
A 15cm PCB ruler designed for Imperial College Robotics Society. It can be easily adapted/rebranded using the KiCad project in this repository.
The recommended specifications for ordering this PCB are as follows: 2 Layers 1.6mm thick FR4 Blue soldermask White silkscreen ENIG surface finish <= 1 oz Copper weight Tented vias (doesn't matter as there are no vias) +- 0.2mm Board outline tolerance * Remove order number
