Page 5: Dvk-Bl654 And Dvk-Bl654Pa Differences
The DVK-BL654PA development board is identical to the DVK-BL654 development board but with one modification – the PCB footprint added for the BL654PA module. Since the BL654PA module operating voltage range is 3.0V to 5.5V (whilst the BL654 is 1.8V to 5.5V), the following power selection switch positions cannot be used on the DVK-BL654PA. - Page 6 BL654PA Development Kit User Guide IO break-out 2.54 mm pitch pin header connectors (plated through-holes) that bring out all interfaces of the BL654PA module – UART, SPI, • QSPI, I2C, SIO [DIO or AIN (ADCs)], PWM, FREQ, NFC – and allow for plugging in external modules/sensors.

Page 15: Swd (Jtag) Interface
When the USB cable is plugged into connector USB2, the USB cable detection output generates a HIGH for USB_DETECT and USB_DETECTp when switch SW11 is in position 2-1 (default) and Atmel MCU SWD (JTAG) signals are routed to the BL654PA SWD interface. This is required to connect the two-wire SWD (JTAG) interface from U14 to the BL654PA SWD (JTAG) interface. - Page 16 Figure 10: USB2 to SWD onboard circuitry routing via analog switch (U24) Table 3 displays the four signals running from Atmel MCU U14 (SWD interface plus SIO_32 and nReset_BLE) to the BL654PA module (SWD interface plus SIO_32 and nReset_BLE).

Remove the jumper on header connector J12 pin 2-1. Then nAutoRUN can be controlled by inserting the jumper onto J12 (pin 2-3) as shown in • Table 5 (this is the default). The BL654PA by default has pull-down enabled on the SIO_35 (nAutoRUN) pin, so the jumper into J12 (pin 2-3) is optional. https://www.ezurio.com/ ©... -

A removable jumper (on J7 and J9) is provided to break the power supply line directly to the module, allowing you to measure current consumption. For normal operation, the jumper on J7 (and J9) must be fitted (and is fitted by default). IMPORTANT: To achieve the optimal power consumption of the BL654PA series module on the development board, see the lp.low.power.deep.sleep.sb smart “... - Page 35 Using Ammeter (DMM) – Cut solder bridge SB1 and connect an ampere meter between the two pins of J7 pins 1-2; and cut solder bridge SB13 and connect an ampere meter between the two pins of J9 pins 1-2. This monitors the current directly. This is when BL654PA is powered using the Normal voltage Mode (BL654PA operated VDD pin and VDD_HV).
