It’s a solder jumper, between the USB and DC inputs.
See the MAX1551 datasheet - joining this would allow you to pull 280mA from the USB connector, else it’s 100mA (the maximum allowed by USB standard without any negotiation). -
Just fyi - these have a beta firmware revision (which is missing some functions like a2dp volume control).
It’s possible to upgrade by making a parallel-spi interface cable (schematics and PC software are on the bluegiga site), and it might be possible to upgrade over UART (but this failed for me).
No public wish lists :(
