3. QN9090 Modules
QN9090 Module board is the QN9090 minimum system board. The module should be
mounted to carrier board as the target. There is a RF connector on this board, which can
be used to RF signal testing.
4. Generic expansion board
The Expansion board available in the development kit is Arduino compatible shields.
They are supplied pre-fitted to the Arduino-compatible header of Carrier Boards in the
development kit.
The Generic Expansion Board has the following features:
•
Arduino-compatible expansion header (in four parts, CN1-CN4)
•
4 user-input buttons (SW1, SW2, SW3, SW4) connected to DIOs on
the QN9090 module on the Carrier Board:
o
SW1 is connected to IO19
o
SW2 is connected to IO15
o
SW3 is connected to IO7
o
SW4 is connected to IO4
•
4 LEDs (D1, D2, D3, D4) connected to DIOs on the QN9090 module
on the Carrier Board:
o
D1 is connected to IO16
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 QN9090 ADC0, with a 0-1.8V DC voltage
swing
•
Infrared Emitting LED Vishay VSMB2948SL connected to QN9090
