Window curtain alarm: common questions

What microcontroller does the Window curtain alarm use?

The Window curtain alarm is built around the NodeMCU1.0(ESP-12E), from the ESP8266 family.

How big is the Window curtain alarm PCB?

The Window curtain alarm measures 99.1 × 62.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Window curtain alarm?

21 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Window curtain alarm design files?

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

Can I use the Window curtain alarm design in my own project?

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

Can I test firmware for the Window curtain alarm 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.
