2.2 Default jumper settings on DK board
s shown in Figure 2, power, JTAG/SWD, UART and I2C enable jumpers are connected
in default. Table 2 and Table 3 show jumper’s function and how to connect.
Figure 2 Board jumper default settings
Table 2 QN9080A MINIDK board’s default jumper settings
Jumper Jumpers Setting Function
JP2 Pin 1,2 shorted QN908x on-board power
JP7
Pin 1,2 shorted QN908x’s power(1.8V)
Pin 2,3 shorted QN908x’s power(3V)
JP8 Pin 1,2 open UART path disable
JP11 Pin 1, 2 open I2C path disable
JP16 Pin 1,2 shorted When DK board powered by
battery, leave it open
2.3 J-Link OB debugger
The J-Link MCUXpresso OB provides both SWD/JTAG and UART interface. Users can
download or update firmware into a QN908x device by using the UART or JTAG/SWD
interface. There is the J-Link connector for programming and debugging off-board target,
shown in Figure 3.

2.4 QN9080 Module
QN908x IC integrates a BLE radio, controller, protocol stack and profile software on a
single chip, which can provide a flexible and easy way to use BLE SoC solution. It also
includes a high performance MCU (32-bit ARM Cortex-M4F), on-chip memory, and
peripherals for users to develop a truly single chip wireless MCU solution.
Shown in Figure 4.
Figure 4 QN9080 Module Board
QN908x Module has MIFA antenna on front of board. So it can work without external
antenna. There is a RF connector that is with switch on RF front-end. You can easily do
RF test by connecting a RF cable to the RF connector.
2.5 GPIO and Arduino interface
On QN908x DK board, the connectors J4, J5, J6 and J7 provide all GPIO connection
output. And it is also compatible to Arduino board interface. The interface schematic is
shown in Figure 5.

2.7 ISP mode jumper
“JP15” is the ISP mode jumper which is used to set QN908x ISP mode. When the jumper
is shorted, the chip mode “PB02” pin is connected to GND and this function is enabled.
When the jumper is open, the ISP mode function is disabled. Shown in Figure 7.

The board provides a SWD/JTAG interface for the usage of external debugger. Shown in
Figure 8.
Figure 8 JTAG interface
2.9 Buttons
As shown in Figure 9 for detailed circuits, the DK board offers three buttons. When using
the buttons “SW1” and “SW2”, the GPIO must be configured as inputs. Logic LOW input
is applied to GPIO when a button is pressed.
Figure 9 Buttons
The button “SW3” is used to reset QN908x chip. Press down the button, QN908x will be
reset.
2.10 LED
The board offers a three colors RGB LED. The connections are shown in Figure 10. The
LED will light up when the corresponding GPIO outputs switch to logic High level. The
control pins of GPIO are QN_PA13, QN_PA25 and QN_PA31. The GPIO QN_PA13 can
work at PWM out mode. So that the brightness of LED can change with PWM pulse
width.
