PIRACK FOR RASPBERRY PI (PIFACE)
PIRACK FOR RASPBERRY PI (PIFACE)
Tech Specs:
- Connect up to 4 accessory boards to the Raspberry Pi - 5V barrel jack for additional power
- Jumpers to select between internal and external power
- Daisy chain multiple Racks for even more expansion
- Re-address SPI accessory boards with jumpers to swap SPI chip enable lines
Jumper settings
Each accessory connector on PiFaceTM Rack has two sets of jumpers. One set labelled (JP9, JP10, JP11 or JP12) selects if the accessory is powered from the Raspberry Pi or from the barrel jack. The other sets of two (JP1 & JP2, JP3 & JP4, JP5 & JP6 or JP7 & JP8) select if the SPI CE lines should be swapped. If you swap CE lines for an accessory, you must change both CE jumpers from their default position.
-If the Raspberry Pi cannot supply enough current to an accessory, place the corresponding jumper in the ‘Ext’ position.
-In most situations the SPI CE lines do not need swaping and the jumpers should be connected in the position without a line printed on the silkscreen. To swap CE lines (GPIO pin 24 and GPIO pin 26) place the corresponding pair of jumpers in the position indicated by a line on the silkscreen.
