Open source insulin pump: common questions
What microcontroller does the Open source insulin pump use?
The Open source insulin pump is built around the ATSAMD21G18A-AUT, from the Microchip SAM family.
How big is the Open source insulin pump PCB?
The Open source insulin pump measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Open source insulin pump?
143 components, from 83 distinct parts. The full bill of materials is listed on this page.
Where can I download the Open source insulin pump design files?
From the UCBioengineering/open_source_insulin_pump repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Open source insulin pump design in my own project?
The repository has no license, so all rights stay with UCBioengineering. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Open source insulin pump without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
