- Will use a large PIC, probably 16bit, possibly dsPIC33 for higher pwm frequencies, and better analog.
- USB mini jack along with a broken out pinheader, for internal connection to the motherboard
- the ability to drive 6 PWM fans, 4 of which should be analog driven trough a simple buck converter(design below) for 3pin Fans versions
- all six should have a 500mA capacity
- two additional PWM 4pin drivers for pumps,(2A) shouldn't be an issue, cause our board will only provide the PWM, and RPM sensing, the computer PS will power them.
- 6 analog inputs (Temp sensors)
- 8 digital I/O (5v tolerant)
- 5pin universal interface like Bus Pirate
- possibly incorporate a cap-sense button support
- Universal LCD connector with as many pins as possible to support as many LCDs
- contrast and backlight adjustment)
- Possibly make it cross platform(windows/linux)
- Setup utility
- configuring of all the outputs inputs and such. something like a picture of the device with pull down menus next to the pins.
- Control/monitoring Wiglet where simple options could be modified, like Fan temp profiles, what to display on the lcd...
- Widget should show all relevant sensor data along with Computer PS voltages, and overall consumption of the board, possibly individual consumption
- Part of the LCD smartie source code and the LCD backpack source could be used, cince lcd smartie already taps stats/emails..and has button support.
- Buck converter Idea
- only using a higher frequency (~0.5-1Mhz) for the pwm, to use cheaper/smaller caps/inductors, A shotky would have to be added
- perhaps use Seeed's led driver IC 500mA one, that is used in the Rainbowdino, it could be cheaper then the one used by geoff.
