About the PCB ESP32 CAN

PCB ESP32 CAN is an open source ESP32 PCB design by PCBrs, published on GitHub. It is a 4-layer board measuring 48.9 × 57.2 mm, with 47 components from 26 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the CP2102N-A01-GQFN24, SN65HVD232 and NCP1117-3.3_SOT223. By type, the board carries 16 capacitors, 14 resistors, 5 diodes, 4 ICs, 3 connectors and 2 transistors.

It belongs with the robotics & motion and iot & wireless designs in this gallery.

From the project

Carte électronique pour la Coupe de France de robotique

La carte principale est basée sur une Teensy 4.1, la communication est faite par Wi-Fi via un ESP32 et la communication interne du robot via un bus CAN. Les cartes sont modulaires et spécifiques, on peut ajouter plusieurs fois le meme types de cartes il faut juste changer l'ID CAN de la carte en soft. Le microcontroleur des cartes périphériques est un STM32F302C8T6.

PCB ESP32 CAN: common questions

What microcontroller does the PCB ESP32 CAN use?

The PCB ESP32 CAN is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the PCB ESP32 CAN?

The PCB ESP32 CAN measures 48.9 × 57.2 mm, has 4 copper layers and is 1.81 mm thick.

How many components are on the PCB ESP32 CAN?

47 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB ESP32 CAN design files?

From the PCBrs/CDR-Electronique repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB ESP32 CAN design in my own project?

The repository has no license, so all rights stay with PCBrs. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PCB ESP32 CAN 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.
