The D1 Mini breakout contains 3 x 3.5mm T/R/R/S jacks that can directly interface to our IR receivers and emitters. Multiple IR emitters can be installed via stereo to mono breakout cables. Custom sensors can also be added easily with 3.5mm to bare wire cables. The Breakout cable shown below is pictures with one IR Receiver and one IR Emitter. The breakout board also has a footprint for an LM75 temperature sensor which is not installed by default, but can be added by special order.

By default we ship boards with the ESP8266 HTTP IR Blaster software which is based on the IR remote ESP8266 with only a few minor modifications:

• Pinout changed to match the D1 mini
• DHCP enabled by default
