Good news - we're open for limited services in Wembley. Ujima House is now actively under refurbishment and we'd love your help in making the space the best it can be.
During this interim period donations and continued membership are greatly appreciated while we transition to our new space.

The Bus Pirate is a low-level interface to:
- raw 2-wire
- raw 3-wire
- PC keyboard
- HD44780 LCDs
It includes an ADC and can bit bash these protocols at the wire level. It can also be put into UART bridge mode, acting as a simple serial port.
brown - GND red - +3.3 orange - +5 yellow - ADC green - VPU blue - AUX purple - CLK grey - MOSI white - CS black - MISO
NB This order depends on attachment as connector is symmetrical and may be inverted.
I have noticed that the sparkfun connector and buspirate uses the following mappings
black – gnd white – 3.3V grey – 5V purple – ADC blue – VExtern green – aux1 yellow – clk orange – MOSI red – CS brown – MISO
