About the L0 ESP32 PCB

L0 ESP32 is an open source ESP32 PCB design by Luos-io, published on GitHub under the MIT license. It is a 2-layer board measuring 20.3 × 34.8 mm, with 23 components from 20 distinct parts.

Its main chip is the esp32, from the ESP32 family. Other key parts include the TPS54232. By type, the board carries 4 resistors, 2 ICs, 2 connectors, 2 diodes, 1 inductor and 1 capacitor.

It belongs with the iot & wireless and dev boards & breakouts designs in this gallery.

From the project

Open-source and real-time orchestrator for cyber-physical-systems, to easily design, test and deploy embedded applications and digital twins.

This folder contains hardwares librairies used by Luos to inspire you to create your own designs: - L0: The base board used by Luos for demonstrastion purpose. - l0-shields: Different shields that can be used directly on the Luos L0 board for added functionality. - STm32f0discoluosshield: a debugging shield equivalent to an L0 for STM32F072B-DISCO dev board. - Breakoutboard: a small add-on board to make any board compatible with Luos L0. - wiringandpower: a set of projects for Luos L0 compatible wires and power input boards. - 00CommonLibraries: a set of Kicad libraries commonly used.

L0 ESP32: common questions

What microcontroller does the L0 ESP32 use?

The L0 ESP32 is built around the esp32, from the ESP32 family.

How big is the L0 ESP32 PCB?

The L0 ESP32 measures 20.3 × 34.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the L0 ESP32?

23 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the L0 ESP32 design files?

From the Luos-io/luos_engine repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the L0 ESP32 design in my own project?

Yes, under the terms of its MIT license, which Luos-io chose for the repository.

Can I test firmware for the L0 ESP32 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.
