On-board QSPI Flash 9 On-board QSPI Flash The GR5515 SK Board integrates a 32 MB QSPI Flash, to expand Flash memory and store application data. Figure 9-1 Expanded QSPI Flash schematic diagram Note: • QSPI Flash pins, buttons (UP, LEFT, RIGHT, DOWN), and Arduino Uno shield connector pins (GPIO_8 and GPIO_9) are multiplexed. -
Page 21: Performance Test
10.1 RF Performance 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 22: 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 connector J10. Therefore, you can connect a test instrument to J10 to test the current. - Page 23 When instantaneous current runs through the 10-ohm resistor, certain voltage drop occurs at the two probes. The voltage drop is in direct proportion to current. Therefore, the oscilloscope display shows a current change Copyright © 2024 Shenzhen Goodix Technology Co., Ltd.
- Page 24 10-3. During a Bluetooth LE event, the power analyzer automatically stores and displays current curve changes in real time. You can zoom in the curves to see current consumption details. For more information, see operational instructions of the corresponding power analyzer. Copyright © 2024 Shenzhen Goodix Technology Co., Ltd.
