Jumper Connectors
The TWR-KW2xDxxx development platform incorporates several headers which allow different MCU
port configurations assisting in the implementation of target applications. (see
Figure 3-1.,
“TWR-KW2xDxxx Connector and Header Details”
).
•
SPI0 TWRPI / TWR_ELEV Select (J17).
— The TWR-KW2xDxxx has the capability to support a SPI for TWRPI boards - to configure,
shunt J17 pin 2-3 (SPI0_PCS), pin 5-6 (SPI0_SCK), 8-9 (SPI0_MOSI), and pin 11-12
(SPI0_MISO). See
Figure 3-8., “TWR-KW24D512 Schematic”
.
— The TWR-KW2xDxxx has the capability to support a TWR_ELEV with another TWR System
- to configure, shunt J17 pin 1-2 (SPI0_PCS), pin 4-5 (SPI0_SCK), 7-8 (SPI0_MOSI), and pin
10-11 (SPI0_MISO). See
Figure 3-8., “TWR-KW24D512 Schematic”
.
•
UART1 / ADC TWRPI Select (J18).
— The TWR-KW2xDxxx has the capability to support a ADC for TWRPI boards - to configure,
shunt J18 pin 2-3 (ADC0_DM1), pin 5-6 (ADC0_DP1), 8-9 (ADC0_SE11), and pin 11-12
(ADC_SE10). See
Figure 3-8., “TWR-KW24D512 Schematic”
.
— The TWR-KW2xDxxx has the capability to support an UART1 connection trough
TWR_ELEV with another TWR System - to configure, shunt J17 pin 1-2 (UART1_TX), pin
4-5 (UART1_RX), 7-8 (UART1_CTS), and pin 10-11 (UART1_RTS). See
Figure 3-8
.
•
UART0 / LED Select (J19/ J20/ J21/ J24).
— The TWR-KW2xDxxx has the capability to support the Blue LEDs on board - to configure,
shunt J19 pin 2-3 (PTD4_LED), J20 pin 2-3 (PTD5_LED), J21 pin 2-3 (PTD6_LED), and J24
pin 2-3 (PTD7_LED). See
Figure 3-8., “TWR-KW24D512 Schematic”
.
— The TWR-KW2xDxxx has the capability to support an UART0 connection trough
TWR_ELEV with another TWR System - to configure, shunt J19 pin 1-2 (UART0_RTS), J20
pin 1-2 (UART0_CTS), J21 pin 1-2 (UART0_Rx), and J24 pin 1-2 (UART0_TX). See
Figure 3-8., “TWR-KW24D512 Schematic”
.

MKW24D512 USB Supply (J6) - TWR-MK24D512 Board Only
The MKW2xDxxx device has an on-board USB port which is configured to provide both power and serial
communication with the target MCU. (see
Figure 3-1., “TWR-KW2xDxxx Connector and Header
Details”
). The following jumpers allow the USB functionality:
•
USB Select - Micro USB AB (J6).
