Apollo3 Blue Plus EVB Quick Start Guide The EVB has these additional features: ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ Low power reference design Apollo3 Blue Plus MCU in the BGA package (AMA3B2KK-KBR) Multiple power/clock options Micro USB Type C connector for power/download/debug On-board PCB (MIFA) antenna FTDI USB-to-SPI adapter/interface RF switch/connector (J1 - Murata MM8430-2610RA1) for BLE PHY testingSegger J-Link debugger Debugger-in port Debugger-out port with connection-indication LED Five user-controll
Apollo3 Blue Plus EVB Quick Start Guide 4. Debug Interface The debug interface is supported by standard J-Link drivers from Segger. Please refer to “Software Development Tools” on page 10 for more details on J-Link debug support. 4.1 Use of External Debugger This EVB also supports the use of an external Cortex SWD debug interface through a standard 10-pin debug header (DEBUG IN - J1) as shown in Figure 3. Figure 3.
Apollo3 Blue Plus EVB Quick Start Guide Figure 4. Apollo3 Blue Plus EVB’s DEBUG OUT Header (J2) To utilize this functionality, use a 10-pin low-pitch standard debug connector to connect the “DEBUG OUT” header (J2) on the EVB to the debug header on the target board. The EVB will automatically detect when the “DEBUG OUT” header is connected to another target board and reconfigure the integrated J-Link to connect to this external board rather than the on-board Apollo3 Blue Plus.
Apollo3 Blue Plus EVB Quick Start Guide 5. Software Development Tools The standard Segger J-Link debug interface is used on the Apollo3 Blue Plus EVB. Please install the latest Segger J-Link software, and configure your preferred development IDE (Keil, IAR, or Eclipse) to use J-Link debug interface.

Apollo3 Blue Plus EVB Quick Start Guide 6. Power Supply Options and Measuring Current There are three power supply options for the Apollo3 Blue PlusEVB: ▪ Operate at 3.3V as provided by the on-board power supply ▪ Operate at 1.8V as provided by the on-board power supply ▪ Provide externally supplied power Figure 6 shows header P19 which is used to select a power configuration through jumper installations, as well as the option to measure the supply current to the MCU with an ammeter.
Apollo3 Blue Plus EVB Quick Start Guide As an example for setting the jumpers on P19, Figure 7 shows the EVB configured for 3.3V operation with jumper across VDD_PS and VDD_MCU for no current measurement. Figure 7. Header P19 Configured for 3.3V Operation - No Current Measurement Figure 8 shows the EVB configured for 3.3V operation with current measuring leads across VDD_PS and VDD_MCU for current measurement. Figure 8. Header P19 Configured for 3.
Apollo3 Blue Plus EVB Quick Start Guide cut to make U8 (VDD_PS_LDO generator) output 1.9V instead of 1.8V in the low-voltage configuration. This will enable current consumption measuring using equipment with a sensing resistor, such as a digital multimeter. Figure 9. Solder Bridge SB1 QS_A3P_1p00 Page 13 2019 Ambiq Micro, Inc.

Apollo3 Blue Plus EVB Quick Start Guide 7. FTDI Interface The on-board FTDI chip (FT4222H) is a SPI to USB data streaming interface from the Apollo3 Blue Plus to the connected PC. Transfer speed can exceed 200KBytes/sec, and the user can send generic data and audio data to the PC over the interface at same time. Audio data is supported in raw PCM (16bit/16Khz), SPP and OPUS formats.
