J2
FTDI serial header. In addition to provide a serial output from K32W061/041, the
Target side of the board can be powered from the FTDI header. The
K32W061/041 supports serial ISP boot from the FTDI header.
J3
32 pins Expansion header connector for debug. All the K32W061/41/041 IOs from
modules and more are available here.
J14
K32W061/041 VBAT current monitor V sense measurement. The V sense can be
measured with a volt meter. Pin 1 (square pad) is positive and pin 2 is negative.
K32W061/041 current is calculated by dividing the measured voltage at J14 by the
V
sense resistance value of 3.3Ω.
J15
Link2 mini USB B-type connector. Powers both the Link2 side of the board and
depending on the JP3, J5 configuration, the K32W061/041 Target side of the
board. Power the board from this connector when using the on-board debug probe
to debug the K32W061/041 Target MCU.
JP1
K32W061/041 Target SWD disable
– 2-position jumper pins.
1.
Jumper “ON” (default) the K32W061/041 Target SWD interface enabled.
Normal operating mode where the Target SWD is connected to either the
on-board
2. Link2 debug probe or an external debug probe.
Jumper “OFF”, the
K32W061/041 Target SWD interface is disabled. Use this setting only
when the on-board Link2 debug probe is used to debug an off-board
Target K32W061/041.
JP2
SWD interface buffer power selection
JP3
K32W061/041 power source selection
1. Jumper fitted in position pin 1 - 2 (default -5V REG). Power source is
either 5V from mini USB connector or FTDI connector, or 4.5V from
3xAAA batteries or 5V from a 7-12V DC power supply connected on J4.
2. Jumper fitted in position pin 2 - 3 (BAT 6V). Power source is 4xAAA
batteries.
See details on Board power diagram Figure 5
JP4
Jumper to route LPC or FTDI to UART RX0 K32W061/041 (to change in pair with
JP7)
JP5
Link2 (LPC4322) force DFU boot
– 2 position jumper pins.
1. Jumper open (default) or shunted to boot mode for Link2 to follow the
normal boot sequence. The Link2 will boot from internal flash if image is
found there. With the internal flash erased the Link2 normal boot
sequence will fall through to DFU boot.
2. Jumper shunted to force the Link2 to DFU boot mode. Use this setting to
reprogram the Link2 internal flash with a new image or to use the
MCUXpresso IDE with CMSIS-DAP protocol.
JP6
JP6 is used to isolate the Link2 debug probe (SPI bridge function) from the
K32W061/041 target to prevent leakage current in power critical applications /
current consumption analysis. JP6 needs to be fitted in position 1 - 2 to use the
SPI bridging function between the K32W061/041 and Link2. This jumper is not
fitted by default
JP7
Jumper to shunt LPC to K32W061/041 or FTDI to UART TX0 K32W061/041 (to
change in pair with JP4)
CN1,
CN2,
CN3,
CN4
Expansion connectors, including Arduino Uno rev3 compatible connectivity.
JM1,
JM2
K32W061/041 module headers
P1
10-pin SWD connector
– The SWD connector is used to debug the K32W061/041
Target from an external debug probe. The same SWD connector can also be used
to connect the on-board Link2 debug probe to an off-board target MCU (for this
JP1 must be shunted).
BP1
User Interface button connected to IO1. Used in some Applications Notes.
