Multi gauge: common questions
What microcontroller does the Multi gauge use?
The Multi gauge is built around the ESP32-S3, from the ESP32 family.
How big is the Multi gauge PCB?
The Multi gauge has 2 copper layers and is 1.6 mm thick.
How many components are on the Multi gauge?
53 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the Multi gauge design files?
From the miata-bot/can-link repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Multi gauge design in my own project?
The repository has no license, so all rights stay with miata-bot. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Multi gauge without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
