Raspberry Pi Header Tap

Here is a tap I created for the Raspberry Pi to allow access to the header pins even though it may be blocked by a "Pi Plate" / Shield that is using the header without pass-through pinheaders.

FT4232H-Based Eee 701 Internals Controller

This controller will be designed for installation into an Eee 700-series netbook to serve the following purposes:

  1. Provide a communications interface to I2C, SPI and UART devices over USB
  2. Control power switching to various internally-mounted low-current (~0-25mA) and high-current (~25-125mA) devices.
  3. Provide non-USB-Host 5V power to the high-current USB devices through high-current SPST switches so as not to overload the USB Bus (Update: This will be done by off-board MOSFETs. There just wasn't enough room on the board to allow it to still fit in the space allocated for the MDC1.5.
