DraadloosDeurbel: common questions

What microcontroller does the DraadloosDeurbel use?

The DraadloosDeurbel is built around the WeMos_D1_mini, from the ESP8266 family.

How big is the DraadloosDeurbel PCB?

The DraadloosDeurbel measures 51.8 × 58.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DraadloosDeurbel?

25 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the DraadloosDeurbel design files?

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

Can I use the DraadloosDeurbel design in my own project?

Yes, under the terms of its MIT license, which pappavis chose for the repository.

Can I test firmware for the DraadloosDeurbel without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
