An interface board to be used with Valve Index BMR assemblies
Note, this listing is NOT A PAIR. To support two BMRs, you need two adapters.
There are three types available
Solder pads
3.5mm input only
1x4 Picoblade input + 3.5mm output
If assembling the Hummingbird headphones, I recommend 1x picoblade+3.5mm and 1x 3.5mm only
The Picoblade adapter is unique in that the 1x4 header is the input for both audio channels. The left channel goes to the BMR and the right channel goes to the 3.5mm. This version has solder jumpers on the back to change the polarity of the right channel.
The solder pad and 3.5mm only adapters have direct connections to the BMRs
The picoblade and 3.5mm variants will be pre-assembled with their necessary headers
