o
D2 is connected to IO6 (same as for the PWM output used
on the Lighting/Sensor Expansion Board to drive the three
white LEDs)
o
D3 is connected to IO3
o
D4 is an optional LED which is not fitted on the supplied
board and shares IO4 with button SW1
•
Potentiometer connected to K32W061/041 ADC0, with a 0-1.8V DC
voltage swing
•
Infrared Emitting LED Vishay VSMB2948SL connected to
K32W061/041 IO20_IR_Blaster
•
USB Mini B port to provide access to K32W061/041 UART1 via IO11
and IO10 of K32W061/041 module (connected via FTDI FT230X driver
device)
•
PCB pads for 4-way GPIO header (3V3, VCC, IO11, IO10), where
IO11 and IO10 can be used to access K32W061/041 UART1 (in this
case, the FTDI driver chip for the USB port must be isolated by
removing resistors R9 and R16).
