ESP32 CAN TEST: common questions
What microcontroller does the ESP32 CAN TEST use?
The ESP32 CAN TEST is built around the TMC2209-LA, from the ESP32 family.
How big is the ESP32 CAN TEST PCB?
The ESP32 CAN TEST measures 45.7 × 45.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP32 CAN TEST?
39 components, from 36 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 ESP32 CAN TEST design files?
From the SamsonChau/PCB 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 ESP32 CAN TEST design in my own project?
The repository has no license, so all rights stay with SamsonChau. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP32 CAN TEST 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.
