This is a new updated version of the Alexander Bierbrauer’s IR transponder for multirotor (drone) racing with EasyRaceLapTimer system. This model has a button to allow changing the transponder code at the field. This minimizes transponder conflicts, especially when racing with other groups using the same ERLT system.

This board is intended to be powered by 5V from a spare servo connector on your receiver or flight controller. The hole in the board is for cable strain relief.

Note: ATTiny85 needs to be programmed with applicable code from EasyRaceLapTimer project. This board has not been tested.

Parts to populate each board:

Optional (but recommended):

10uF 1206 Capacitor

Helpful:

SOP-8 programming clip
