Inserting Shield into Wemos D1 Mini

Make sure the the 2 IR Leds are at the same end as teh PCB antenna on the Wemos D1 Mini (opposite end to the usb connector). All pins of the shield should be inserted into the female headers.

LEDs

There are 2 LEDs. The first is located on the Wemos D1 Mini (usually blue). This LED is on the same IO pin as the IR send pin of the shield. After start-up it will always appear on. If this is an issue, it is relatively easy to remove this LED with a soldering iron. The second LED is at the front of the shield and after startup will briefly flash red as IR signals are transmitted. However, when both IR power jumpers are installed, the LED may not flash or be very dim. This is normal behaviour and is related to the use of the red LED as part of the constant current driver circuit for the IR LEDs.
