Entrenador: common questions

What microcontroller does the Entrenador use?

The Entrenador is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Entrenador PCB?

The Entrenador measures 115 × 61 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Entrenador?

64 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Entrenador design files?

From the FrizzyElectronics/Entrenador repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Entrenador design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Entrenador without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
