1. Bus-power mode: The board can be powered using the USB cable. The onboard LDO is used to regulate output voltage to 3 V and supplies power to all parts on the board. 2. Battery-power mode: The CR2032 supplies power to QN9020 and optional sensor connector when it is in battery-power mode. The J-Link 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. Fig 4.

Just as illustrated in diagram as below, USB Dongle receives commands from QTool via virtual COM port, by which QN902x would be initialized as a Master or Slave device. All tests can be performed by QTool after initialization. R A F T D R A Fig 16. Dongle Block Diagram 3.2 Dongle Connection QN9020 USB dongle is a USB interfaced device with a QN9020 packed in. With driver and SDK installed in computer (refer to QN9020 quick start guide), user can use QTool in SDK to control the QN902x in dongle to work as a central device. The MiniDK board with USB power supply from computer works as a peripheral device. The connection of the dongle is illustrated as blow figure. For QTool usage, please refer to QTool User Manual v1.1 in SDK. Fig 17. Dongle Connection 4.
