From the project

Open Hardware respository from Laboratório Hacker de Campinas

LIVE em formato Hands On Construindo o nova versão da placa de desenvolvimento nodeLHC ESP32, com o Pedro Minatel, utilizando a ferramenta Kicad, o módulo escolhido foi o ESP32 um microcontrolador de baixo custo da Espressif.

Em 2015 durante as oficinas de IoT no Hackerspace, criamos uma primeira versão do nodeLHC com o módulo ESP8266. Assim as pessoas aprenderam as diferentes etapas para construção de placa de circuitos impressos, também soldagem dos componentes da placa de desenvolvimento e programação para o módulo.

Lhc tijolo32 board: common questions

What microcontroller does the Lhc tijolo32 board use?

The Lhc tijolo32 board is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.

How big is the Lhc tijolo32 board?

The Lhc tijolo32 board measures 24 × 84.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lhc tijolo32 board?

44 components, from 33 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 Lhc tijolo32 board design files?

From the lhc/Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Lhc tijolo32 board design in my own project?

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

Can I test firmware for the Lhc tijolo32 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.
