KW45B41Z-EVK Board User Manual
Board feature Target MCU feature used Description
LPUART/LIN Two LPUART modules (LPUART0
and LPUART1)
• LPUART0:
– Connects to a 1x4 pin LIN header through a LIN
transceiver for an external LIN connection
– Connects to one of the two mikroBUS socket connectors
for an external UART connection
– Connects to one of the four Arduino socket connectors
for an external UART connection
– Can be used for MCU-Link connection in place of
LPUART1
• LPUART1:
– Supports a USB-to-UART bridge for connecting MCU-
Link to the target MCU
– Connects to another Arduino socket connector for an
external UART connection
– Can be used for LIN connection in place of LPUART0
LPSPI One of the two LPSPI modules
(LPSPI1) with four peripheral chip
selects (PCS0, PCS1, PCS2, and
PCS3)
• PCS0: Connects to 16 Mbit QSPI NOR flash memory,
which supports over-the-air (OTA) programming
• PCS1: Connects to one of the two Ranger 4 socket
connectors
• PCS2: Connects to one of the four Arduino socket
connectors
• PCS3:
– Supports a USB-to-SPI bridge for connecting MCU-Link
to the target MCU
– Provides an alternative SPI connection to PCS0
connection
– Provides an alternative SPI connection to PCS2
connection
– Connects to one of the two mikroBUS socket connectors
LPI2C One of the two LPI2C modules (LPI2
C1)
LPI2C1 module connects to:
• MCU-Link through a USB-to-I2C bridge connecting MCU-
Link to the target MCU
• Power management integrated circuit (PMIC)
• Accelerometer
• One of the two mikroBUS socket connectors
• One of the four Arduino socket connectors
RF 2.4 GHz radio A PCB-integrated inverted-F antenna and an SMA connector
for RF operation
Accelerometer 3-axis, 12-bit, compact digital accelerometer
mikroBUS mikroBUS socket with two 1x8 position receptacles
Arduino Arduino UNO board compatible socket with four receptacles
(1x8, 1x10, 1x8, and 1x6 positions)
Ranger 4 Ranger 4 UWB board compatible socket with two
receptacles (2x10 and 2x8 positions)
MCU-Link USB USB 2.0 micro-B connector for creating MCU-Link high-
speed USB connection to the host computer, and providing 5
V power to the board
