This board is useful for that people who want more from theyr raspberry pi. the board have the following features:
- 16 PWM channels
- 16 IO pins
- 8 ADC channels
- 8 DAC channels

Plus:
- Power controller (with on-off buttons)
- RTC with alarms
- Level shifter for UART, I2C and SPI port

Everything on the board will be controlled by i2c bus, and with a little python script you can control also the power of your Pi. The power controller is a pic which switch 2 mosfets and monitorize 2 GPIO pins letting you safely switch off your Pi both from software and harware buttons. Plus you can program a power on time through the RTC alarm so you can turn on your Pi at a certain time.

I wrote some python library and bash scripts for the board. Maybe someone can review the code and improve it.

If someone is intrested in the board I'm here :)
Hope this board can help someone like it did for me!
