Klingel hass: common questions

What microcontroller does the Klingel hass use?

The Klingel hass is built around the WeMos_D1_mini, from the ESP8266 family.

How big is the Klingel hass PCB?

The Klingel hass measures 82 × 97.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Klingel hass?

43 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Klingel hass design files?

From the paulin1C/klingel_hass repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Klingel hass design in my own project?

The repository has no license, so all rights stay with paulin1C. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Klingel hass 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.
