About the LBEAST Driver Shield

LBEAST Driver 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 78 components from 43 distinct parts.

Its main chip is the ESP32-S3-2x22, from the ESP32 family. Other key parts include the LM2576HVS-5, MTJ-883X1, ADM3057ExRW, LAN8720A and BTS7960B. By type, the board carries 22 capacitors, 22 resistors, 11 ICs, 10 diodes, 5 connectors and 5 switches.

It belongs with the 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.

Motor Control ECU for High-Current Actuator Applications:

The LBEAST Driver Shield ("LBDS" or "Driver Shield") is a specialized ECU derived from the Universal Shield, designed for high-current motor control applications. It integrates a BTS7960 H-bridge motor driver with hall sensor feedback support, while maintaining the core connectivity features of the Universal Shield (Ethernet, CAN-FD, and aux ports).

LBEAST Driver Shield: common questions

What microcontroller does the LBEAST Driver Shield use?

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

How big is the LBEAST Driver Shield?

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

How many components are on the LBEAST Driver Shield?

78 components, from 43 distinct parts. The full bill of materials is listed on this page.

Where can I download the LBEAST Driver 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 Driver 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 Driver 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.
