Access to all 46 BL654PA
series module signal pins (SIO’s = Signal Input /Output) is available on plated-through holes (for
2.54 mm pitch header connectors) on J44, J47, J48, J41, J29, J1, J12, J1, J5, J17, J21, J6, and J36.
Note:
The BL654PA module signal pins designation SIO (Signal Input /Output).
▪
DEFAULT type is DIO (Digital Input or Output) or UART (on fixed pins)
▪
ALTERNATE type is either AIN (Analog Input ADC), I2C, SPI, QSPI, DIO (on fixed pins), PWM, FREQ, and NFC
▪
DIO or AIN functionality is selected using the GpioSetFunc() function in
smart
BASIC
▪
I2C, UART, SPI, QSPI controlled by xxxOPEN() functions in
smart
BASIC
▪
SIO_05 to SIO_08 are DIO by default when $autorun$ app runs on power up
▪
SIO_09 and SIO_10 are NFC pins by default; they can be set to alternative function SIO using the GpioSetFunc()
function in
smart
BASIC
These breakout connectors can interface to a wide array of sensors. The BL654PA is user configurable through the
smart
BASIC application script to change each SIO pin from the default function (DIO, UART) to alternate functions (AIN
(ADC), I2C, SPI, QSPI, DIO), PWM, FREQ, and NFC. The BL654PA development kit incorporates additional fly-lead cables
inside the box to enable simple, hassle-free testing of these multiple interfaces.
shows the BL654PA module pins that are brought out to plated through Holes (suitable for 2.54 mm pitch headers).

SI0_ 01
J44 connects to SIO_00 and SIO_01 via 0R
resistors R127 and R128.
By default, the optional external 32.768 kHz
crystal circuit is not connected to BL654PA as
SB8 and SB9 are open.
