Tucked ever-so-gently along the side of the headset, we find the IR Board. We knew something had to keep all those IR LEDs under control.

Populating the board are a few more silicon-flavored morsels:

STMicroelectronics STM8S003K3 8-bit MCU

Texas Instruments TPS54478 buck converter

STMicroelectronics STP16CPC26 low voltage 16-bit constant current LED sink driver

Vishay VSOP58438 IR remote control preampifier circuit

Texas Instruments TPS7A3701 1 A LDO Regulator
