- Cambios generales: Ahora open wound está bajo licencia GPLv3. Open wound usa versionamiento semántico. - Esclavos version 1.0.0: Cambios menores en PCB. El microcontrolador pasa a ser parte de la placa, no un módulo Arduino. Los pines sin usar son salidas a nivel bajo no conectadas en lugar de entradas a masa. Se añade un conector AVRISP de seis pines. Se añade un conector de debug. Placa diseñada en SMT.. Mejorado el método de conexión a la plancha sensora. Ahora se usan…

Open wound: common questions

What microcontroller does the Open wound use?

The Open wound is built around the ATMEGA328P-A, from the AVR/Arduino family.

How big is the Open wound PCB?

The Open wound measures 45.1 × 26 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Open wound?

23 components, from 19 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 Open wound design files?

From the akornsys-rdi/open-wound repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Open wound design in my own project?

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

Can I test firmware for the Open wound 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.
