Controller: common questions
How big is the Controller PCB?
The Controller measures 65 × 62 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Controller?
47 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the Controller design files?
From the Karpova-Lab/syringe-pump repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Controller design in my own project?
The repository has no license, so all rights stay with Karpova-Lab. Use it as a reference, and ask the author before reusing the design.
