RaspberryI2Cextender: common questions
What microcontroller does the RaspberryI2Cextender use?
The RaspberryI2Cextender is built around the RASPBERRY_PI_2_3, from the Raspberry Pi family.
How big is the RaspberryI2Cextender PCB?
The RaspberryI2Cextender measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the RaspberryI2Cextender?
18 components, from 11 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 RaspberryI2Cextender design files?
From the ReshapeTUe/SoftRoboticControlUnit repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the RaspberryI2Cextender design in my own project?
The repository has no license, so all rights stay with ReshapeTUe. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the RaspberryI2Cextender 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.
