Can gauge interface: common questions

What microcontroller does the Can gauge interface use?

The Can gauge interface is built around the PIC16F1459-IP, from the PIC family.

How big is the Can gauge interface PCB?

The Can gauge interface measures 97.5 × 105 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Can gauge interface?

52 components, from 35 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 Can gauge interface design files?

From the sam-rba/can-gauge-interface 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 Can gauge interface design in my own project?

Yes, under the terms of its GPL-3.0 license, which sam-rba chose for the repository.

Can I test firmware for the Can gauge interface without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
