About the ACPI PCB

ACPI is an open source ESP32 PCB design by Snt8, published on GitHub. It is a 2-layer board measuring 60 × 50 mm, with 37 components from 22 distinct parts.

Its main chip is the ESP32-C3-WROOM-02, from the ESP32 family. Other key parts include the AP2112K-3.3, MPU-6050, QMC6308, AP2112K-1.8 and TXS0102DCU. By type, the board carries 11 capacitors, 10 resistors, 7 ICs, 4 connectors, 2 transistors and 2 diodes.

It belongs with the iot & wireless designs in this gallery.

From the project

Asistente de Cruce Peatonal para personas con discapacidad visual

El sistema combina hardware en el borde (Edge Computing) con sensores magnéticos e inerciales locales en un brazalete (wearable) y en un semáforo (infraestructura). Utiliza comunicación local ultrarrápida (ESP-NOW) entre nodos y telemetría por Bluetooth Low Energy (BLE) hacia una aplicación móvil integrada con Grafana Cloud para monitorear la seguridad de la sesión.

ACPI: common questions

What microcontroller does the ACPI use?

The ACPI is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the ACPI PCB?

The ACPI measures 60 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ACPI?

37 components, from 22 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 ACPI design files?

From the Snt8/ACPI 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 ACPI design in my own project?

The repository has no license, so all rights stay with Snt8. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ACPI 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.
