Page 18: On-Board Qspi Flash
To use QSPI flash pins, disconnect these pins from buttons, GPIO8, and GPIO9, and solder a zero-ohm resistor at the corresponding DNI resistance part. Figure 9-2 Connections shared by buttons and QSPI flash pins Copyright © 2020 Shenzhen Goodix Technology Co., Ltd. -
Page 19: Performance Test
10 Performance Test 10.1 RF Test The GR5515 SK Board reserves a small RF connector (J50), which can be connected to a spectrum analyzer or a Bluetooth LE tester (for example, TLF3000) to test the RF performance of the GR5515 SK Board. -
Page 20: Current Consumption Test
10.2 Current Consumption Test You can test the current consumption of the GR551x SoC on the GR5515 SK Board with a test instrument. On the board, VBAT powers VBATH, VBATL, and VBAT-RF of the GR551x SoC through the jumper pin J10. Therefore, you can connect a test instrument to J10 to test the current. - Page 21 10-3. During a Bluetooth LE event, the power analyzer automatically stores and displays current curve changes for the moment. You can zoom in the curves to see current consumption details. For more information, see operational instructions of the power analyzer. Copyright © 2020 Shenzhen Goodix Technology Co., Ltd.
