The Infrared Module that I chose was a TruOpto part HRM138BB5100 available from Rapid (PN: 55-0902).
IR Module: HRM138BB5100
Capacitor: 47 μF
R1: 4.7 kΩ
R2: 100 Ω
Many designs on the net don’t use the resistors or capacitor. R1 is important for good switching and some noise immunity. R2 and the capacitor help regulate supply to the detector. The VCC was wired to the Olimexino-85 3.3V VCC pin 8,
GND was connected to pin 7,
The Output pin was wired directly to Pin 5 (PB4)
