1.2 Additional resource
For additional resources, visit
http://www.nxp.com/products/microcontrollers/key_feature/bluetooth.
2. Hardware description
The QN9020 mini development board provides easy access to peripherals such as
buttons, Piezo buzzer and LED. The board also provides useful interfaces such as a USB
port for UART communication and JLink debug, and a GPIO/optional sensor board
connector.
A USB Dongle is a Bluetooth device powered by the QN9020. It acts as a master when
communicating with the QN9020.
2.1 Hardware overview
The hardware blocks in the QN9020 Mini DK, and the functional relationship of each main
component, are shown in Figure 1.

2. Battery-power mode: The CR2032 supplies power to QN9020 and optional sensor
connector when it is in battery-power mode. The JLink OB still uses the LDO as power
supply via USB cable. When using USB interface as a power supply, connect the
jumper J11 pin 2 and pin 3; see Figure 4.

2.4 Segger JLink OB part
The Segger Jlink OB offers the SWD and UART interface. Users can download or update
firmware into a QN9020 device by using the UART or SWD interface. Furthermore, it is
convenient to debug the program for a QN9020 device using SWD interface.
To program or debug the QN9020 device using the Segger JLink OB, the 0  resistors
R37, R38 should be soldered; see Figure 6.
Fig 6.
Connect R37, R38
In order to use a USB to UART bridge for the QN9020 download, the solder bridge SB3,
SB4 should be shorted; see Figure 7.

2.7 QN9020 Reset button
The reset button is used to provide hardware reset to the QN9020 device. When
programming the QN9020 using UART interface of Segger JLink OB, the reset button
should be pressed first to ensure that QN9020 is in boot mode. See Figure 10 for the
detailed circuit.

The QN9020 board offers two programmable LEDs, which are connected to the QN9020
device GPIO.
LED1 and LED2 are connected to GPIO P0.5 and P0.6 respectively. The connections are
shown in Figure 11. The LEDs are powered-up when the corresponding GPIO outputs
switch to logic low level.

The QN9020 board offers two buttons which are connected to QN9020 device GPIO.
Button 1 and button 2 are connected to GPIO P1.4 and P1.5 respectively. See Figure 12
for detailed circuits.
When using the buttons, the GPIO P1.4 and P1.5 must be configured as inputs. Logic low
input is applied to QN9020 when a button is pressed.

2.12 Current measurement
The jumper J12 is used to measure the QN9020 device current. In current test mode, the
digital ammeter should be connected in series with J12. In the other modes, pin 1 and
pin 2 of J12 are shorted. A jumper cap is used to short the pins.
