About the Rj45can power PCB

Rj45can power is an open source ESP32 PCB design by ppetr, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 60 × 50 mm, with 44 components from 28 distinct parts.

Its main chip is the ESP32-WROOM-32D, from the ESP32 family. Other key parts include the MAX17610, MAX15062A and SN65HVD235. By type, the board carries 15 resistors, 7 diodes, 7 capacitors, 6 connectors, 4 ICs and 3 jumpers.

From the project

SW and HW for an inexpensive home automation communication network based on the CAN bus

Disclaimer: This is not an officially supported Google product._

This project aims to create both SW and HW for an inexpensive home automation communication network based on the CAN bus using common components and infrastructure.

Eventually it will contain hardware plans (KiCAD) and software to control individual modules.

At the moment subdirectories contain work in progress, untested, and not suitable for any use whatsoever.

Rj45can power: common questions

What microcontroller does the Rj45can power use?

The Rj45can power is built around the ESP32-WROOM-32D, from the ESP32 family.

How big is the Rj45can power PCB?

The Rj45can power measures 60 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rj45can power?

44 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rj45can power design files?

From the ppetr/home-automation-CAN repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Rj45can power design in my own project?

Yes, under the terms of its Apache-2.0 license, which ppetr chose for the repository.

Can I test firmware for the Rj45can power 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.
