About the PCB C

PCB C is an open source ESP32 PCB design by dragondgold, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 54 × 54 mm, with 46 components from 26 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the MCP1501T-33E/CHY, BQ24392RSER, MS563702BA03-50, BMX055 and NTB0104BQ,115. By type, the board carries 15 capacitors, 10 ICs, 9 resistors, 5 connectors, 3 modules and 1 crystal.

From the project

Plataforma educativa basada en un satélite CanSat

El objetivo principal del proyecto es el de proveer un satélite tipo CanSat completamente funcional y listo para ser utilizado, con una Estación Terrena para la comunicación con el mismo, a modo de plataforma educativa que permite no solo ser utilizada por estudiantes sin modificación alguna, sino que provee la capacidad de ser expandida para agregar o mejorar las funcionalidades básicas dando lugar a los estudiantes a experimentar libremente sobre una plataforma segura.

PCB C: common questions

What microcontroller does the PCB C use?

The PCB C is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the PCB C?

The PCB C measures 54 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB C?

46 components, from 26 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 PCB C design files?

From the dragondgold/AtSat repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

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

Yes, under the terms of its GPL-3.0 license, which dragondgold chose for the repository.

Can I test firmware for the PCB C 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.
