| Spec | Single or dual USB adapter for WRAP.1C / WRAP.1D / WRAP.1E / WRAP.2D / WRAP.2E boards. The USB controller inside AMD Geode SC1100 supports USB 1.1. |
| Includes | wrusb adapter, 10 pin cable assembly, header, 0603 zero ohm resistors |
| Installation | Solder the 5x2 pin header on the WRAP board. Modify power circuit as needed. Connect the adapter using the flat cable. Enter S during memory test to get into BIOS setup, enable USB there (old BIOS versions don't have this option, and will require upgrade). |
| Issues |
Existing WRAP enclosures don't have USB cutouts, mechanical modifications will
be needed.
The 5V linear regulator (78L05) on the WRAP board is limited to 100 mA, and is very inefficient at higher input voltages. Should be ok for low power flash keys or self-powered hubs / peripherals. Otherwise modifications wil be needed. Either connect your own 5V supply to the WRUSB adapter, or modify the WRAP board for 5V operation:
WRAP.1C / WRAP.1D / WRAP.1E = install supplied 0 ohm resistors in
locations R101 and R102 (bottom side).
