Accelerometer network module based on the FXLS8471Q. The chip select is shifted through the module to other modules using the D-Flip Flop (used like a shift register). Onboard indicator shows which module is selected.
Signals flow from J1 to J2 (i.e. The next module in the chain gets attached to J2).
J1 Pinout: 1 - Shift Reset (Resets all D-Flip Flops to 0) 2 - FF Clock 3 - Chip Select (Value shifted through the D-Flip Flops) 4 - SPI Clock 5 - SPI MOSI 6 - SPI MISO 7 - VCC (2V - 3.3V) 8 - GND
Rev P1 corrected a mistake with the shift circuit and added labels.
