List of Figures

1. Schematic of AMBUSH hardware
2. Physical layout of the SURF board. Connectors are shown in red, diagnostic LEDs in green and jumpers in blue.
3. Locations of the most invasive kluges required on the SURF board. Refer to Sec. 2.4 for explanation.
4. Regulator schematic
5. LP2975 schematic
