About the Compostaje PCB

Compostaje is an open source ESP32 PCB design by dani0421, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 103 components from 35 distinct parts.

Its main chip is the ESP32-WROOM-32, from the ESP32 family. Other key parts include the TLP281-4GB(F), L298N, AMS1117-5.0, AMS1117-3.3 and LM393. By type, the board carries 36 resistors, 19 diodes, 18 capacitors, 9 ICs, 8 transistors and 8 connectors.

From the project

Seleccionar el nivel de compostaje que el dispositivo contiene. Visualizar por medio de pantalla el tiempo que falta para finalizar el proceso. Notificar al usuario cuando los filtros requieran ser reemplazados. Evitar que el dispositivo genere malos olores. * Notificar al usuari

Compostaje: common questions

What microcontroller does the Compostaje use?

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

How big is the Compostaje PCB?

The Compostaje measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Compostaje?

103 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Compostaje design files?

From the dani0421/Compostaje repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Compostaje design in my own project?

The repository has no license, so all rights stay with dani0421. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Compostaje 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.
