About the LBEAST Universal Shield

LBEAST Universal Shield is an open source ESP32 PCB design by scifiuiguy, published on GitHub under the MIT license. It is a 2-layer board measuring 118 × 84.5 mm, with 71 components from 38 distinct parts.

Its main chip is the ESP32-S3-2x22, from the ESP32 family. Other key parts include the LM2576HVS-5, LAN8720A and ADM3057ExRW. By type, the board carries 18 capacitors, 13 diodes, 12 connectors, 12 resistors, 9 switches and 4 ICs.

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

From the project

Location-Based Entertainment Activation Standard Toolkit - designed to streamline deployment of professional-grade multiplayer VR LBE in venues using immersive theater actors, standardized large hydraulics for motion and haptics, embedded systems for button input and small haptic feedback with vibrators and kickers, & AV OSC for lighting and sound.

Plug-n-Play Embedded Systems - an Absolute Necessity for Next-Level LBE:

The LBEAST Universal Shield ("LBUS" or "Uni-Shield") is a multi-platform ECU that provides unified connectivity and control for all LBEAST firmware applications. But what is it for? What does it do? ECU? What the heck is even that?

It's sort of like the little computer hidden behind the dashboard in your car. It's not a supercomputer... quite the opposite. It costs a few dollars to buy a few dev boards on Amazon and deploy them as ECUs by flashing programs onto them. If you've done IoT with Arduino, ESP32, or STM32...…

LBEAST Universal Shield: common questions

What microcontroller does the LBEAST Universal Shield use?

The LBEAST Universal Shield is built around the ESP32-S3-2x22, from the ESP32 family.

How big is the LBEAST Universal Shield?

The LBEAST Universal Shield measures 118 × 84.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the LBEAST Universal Shield?

71 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the LBEAST Universal Shield design files?

From the scifiuiguy/LBEAST_Unreal repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the LBEAST Universal Shield design in my own project?

Yes, under the terms of its MIT license, which scifiuiguy chose for the repository.

Can I test firmware for the LBEAST Universal Shield 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.
