ESP Interface Board: common questions
What microcontroller does the ESP Interface Board use?
The ESP Interface Board is built around the ESP32-DEVKITC-VE, from the ESP32 family.
How big is the ESP Interface Board?
The ESP Interface Board measures 69 × 86 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP Interface Board?
21 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the ESP Interface Board design files?
From the LeoWatti99/CANTram-Framework repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ESP Interface Board design in my own project?
Yes, under the terms of its GPL-3.0 license, which LeoWatti99 chose for the repository.
Can I test firmware for the ESP Interface Board 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.
