About the Group5-ENGG3000 PCB

Group5-ENGG3000 is an open source ESP32 PCB design by TheWasian, published on GitHub under the MIT license. It is a 4-layer board measuring 76 × 40 mm, with 48 components from 29 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the TPS63001DRCR and CN3085. By type, the board carries 25 resistors, 9 capacitors, 2 ICs, 2 transistors, 2 connectors and 2 LEDs.

It belongs with the sensors designs in this gallery.

From the project

The three-board player tracker uses one sensor on each ESP32. See the setup guide for wiring, the current 35/35 cm sensor gaps, configurable physical hole positions, calibration and builds. The single AccessPoint firmware now serves the live cone dashboard at http://192.168.4.1/

The three-board player tracker uses one sensor on each ESP32. See the setup guide for wiring, the current 35/35 cm sensor gaps, configurable physical hole positions, calibration and builds. The single AccessPoint firmware now serves the live cone dashboard at http://192.168.4.1/ and connects to the existing game UI. It includes spike rejection, position smoothing and six target centres within the configured beam overlap. Any valid sensor pair can track; all three are preferred when consistent. The website and modular backend share SensorService.js`, including fresh-frame scoring and…

Group5-ENGG3000: common questions

What microcontroller does the Group5-ENGG3000 use?

The Group5-ENGG3000 is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Group5-ENGG3000 PCB?

The Group5-ENGG3000 measures 76 × 40 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the Group5-ENGG3000?

48 components, from 29 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 Group5-ENGG3000 design files?

From the TheWasian/Group5-ENGG3000 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Group5-ENGG3000 design in my own project?

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

Can I test firmware for the Group5-ENGG3000 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.
