  • Page 5 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 14 The coin cell operation of BL654PA module on the DVK-BL654PA devboard is NOT possible. A J34 coin cell holder cannot be used on the DVK-BL654PA SW6 default and only valid position is 3V3/1V8. SW6 position coin cell is not valid for the BL654PA.
  • Page 15 USB2 cable plugged in. The development board provides access to the BL654PA module two-wire SWD interface on JP1 via analog switch U24. This is required for customer use, since the BL654PA module supports smartBASIC runtime engine firmware over JTAG (as well as over UART).

  • Page 18 UART TTL (3.3V) converter cable using J1. Fitting a jumper in J35 also allows the BL654PA UART to be routed to Atmel MCU UART (signal also on J19 and net names beginning with IMCU_) via open solder bridges SB16 to SB19 shown in Figure 13.
  • Page 19 The J12 header connector allows the USB_DTR signal from the FTDI chip to be disconnected from the BL654PA. To connect the BL654PA nAutoRUN pin SIO_35 (pin 5) to PC FTDI USB_DTR line via the J12 header connector, do the following: ▪...
  • Page 20 (SIO_35) must be configured to select between these two modes. ▪ VSP Bridge to UART mode takes data sent from phone or tablet (over BLE) and sends to BL654PA to be sent out of the BL654PA UART (therefore data not stored on BL654PA).

  • Page 29 Figure 17: SPI EEPROM schematic and PCB For a working example of the BL654PA SPI interface using the SPI EEPROM (U2), a smartBASIC application for this will be available in the future in the GitHub smartBASIC sample application repository on the BL654PA product page at https://github.com/LairdCP/BL654PA-Applications.
  • Page 30 Refer to the smartBASIC application script example btn.button.led.test.sb in the GitHub smartBASIC sample application repository on the BL654PA product page at https://github.com/LairdCP/BL654PA-Applications The LEDs are active high, meaning that writing a logical one (“1”) to the output pin illuminates the LED.
  • Page 31 The NFC antenna input connector (CON2) allows the Laird supplied flex-PCB NFC antenna to be plugged in. The BL654PA module NFC circuit uses two pins, pin 59 (NFC1/SIO_9) and pin 57 (NFC2/SIO_10) to connect the antenna. These pins are shared with GPIOs (SIO.09 and SIO.10). BL654PA NFC pins are enabled by default. NFC can be disabled via smartBASIC application.

  • Page 33 (default) to stay within ±250 ppm. The BL654PA also allows, as an option, to connect an external higher accuracy (±20 ppm) 32.768 kHz crystal to the BL654PA-SX-xx pins SIO_01/XL2 (pin 41) and SIO_00/XL1 (pin 42). This provides improved protocol timing and helps with radio power consumption in the system standby doze/deep sleep modes by reducing the time that the Rx window must be open.
  • Page 34 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” file in the GitHub smartBASIC sample application repository on the BL654PA product page at https://github.com/LairdCP/BL654PA-Applications...
