About the PCB pecho

PCB pecho is an open source ESP32 PCB design by fg-edu-tep, published on GitHub. It is a 2-layer board measuring 102.9 × 83.2 mm, with 12 components from 8 distinct parts.

Its main chip is the ESP32-S3-DEVKITC-1-N8R2, from the ESP32 family. Other key parts include the module_mpu6050 and module_bme280. By type, the board carries 7 connectors, 4 ICs and 1 resistor.

It belongs with the sensors designs in this gallery.

From the project

Sistema de monitoreo biométrico distribuido basado en ESP32. Varios dispositivos vestibles (reloj, gafas, pecho, sensor GSR) miden señales fisiológicas y de movimiento, y las transmiten de forma inalámbrica por ESP-NOW a un receptor central que las expone como JSON vía HTTP.

Proyecto de la asignatura Fundamentos de Electrónica (Universidad de los Andes).

Cada dispositivo sensor transmite tramas de tamaño fijo (88 bytes) usando el protocolo propio ESB-P (ESP-NOW Sensor Broadcast Protocol, ver ESB-PESP-NOW SENSOR BROADCAST PROTOCOL DRAFT 1.pdf`). Cada trama tiene:

PCB pecho: common questions

What microcontroller does the PCB pecho use?

The PCB pecho is built around the ESP32-S3-DEVKITC-1-N8R2, from the ESP32 family.

How big is the PCB pecho?

The PCB pecho measures 102.9 × 83.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB pecho?

12 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB pecho design files?

From the fg-edu-tep/MENTORU repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB pecho design in my own project?

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

Can I test firmware for the PCB pecho 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.
