36 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Internet Interrupter v1 design files?
From the M0LTE/pi-transceiver repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Internet Interrupter v1 design in my own project?
The repository has no license, so all rights stay with M0LTE. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Internet Interrupter v1 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
