Laptop Power
USB Hub
GPS
USB ⇔ Serial / Parallel (and eventually to I2C)
USB keypad
Universal Power
- Requirements
- USB hub: 5 volts, 2 amps
- Geko 201: 3 volts
- Laptop: 20 volts, 3.5 amps
- BWR-5/6-3.3/7-D12 (12v in, 5V 6A and 3.3V 7A out), $70
- 100W DC-DC ATX
- 100 watt EPIA power supply (specs)
- While the ITPS seems to be popular when combined with a mini-ITX power supply in the car, it may be simpler and cheaper for me to simply use a 12v LDO regulator, but only turn power on to the perhipherals when a USB connection from the laptop is detected (which makes a ton of sense, really...)
