Project description
The IRBridge can record and emit infrared commands - configured by a webinterface, accessible via Alexa, running on an ESP8266.
A more detailed description can be found on hackster.io.
Repository contents
- C++ code that is running on the ESP8266, based on the Arduino core (in /code/esp8266)
- HTML/CSS/JS for webinterface, based on vue.js and Bulma (in /code/web)
- Schematic and PCB for the underlying electronics, created in KiCAD (in /pcb)
- Enclosure design, created in FreeCAD (in /cad)

Questions
How big is the IRBridge PCB?
It measures 44.1 × 10 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IRBridge use?
45 parts, built around the AP2112K-3.3, VSMB2948SL and PN2907A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the IRBridge KiCad files?
From the harbra/IRBridge repository on GitHub, at the commit this page was made from: the board is pcb/irbridge.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the IRBridge design in my own project?
Its repository states no licence, so its author keeps all rights: ask harbra before reusing the design.
