2.3 USB interface
The LPCXpresso55S36 board has three USB connectors, each can accept 5 V external
power. Two out of the three USB connectors can work as both USB ports and power
connectors. The third one only works as a power connector.
The table below explains the LPCXpresso55S36 USB connectors.
Part identifier Connector type Device Description
J3 USB 2.0 micro-AB
receptacle
ZX62D-AB-5P8(30)
(Hirose Electric)
Connects to full-speed USB host and device
controller (USB0) of the target MCU (LPC5536).
The USB0 port can work in either Host or Device
mode. In USB0 Host mode, the J2 connector must
be used as the power supply source (5 V) for the
board. In USB0 Device mode, the J3 connector can
serve as a power supply source (5 V) for the board.
J2 USB 2.0 micro-B
receptacle
ZX62D-B-5PA8(30)
(Hirose Electric)
Supplies 5 V power to the target MCU and
peripheral circuitry, excluding MCU-Link debug
probe. When the target MCU USB0 port is in Host
mode, the J2 connector provides USB host power
for the J3 connector.
J1 USB 2.0 micro-B
receptacle
ZX62D-B-5PA8(30)
(Hirose Electric)
Used to create MCU-Link high-speed USB
connection to the host computer. J1 is also used to
provide a 5 V supply to the board.

2.4 USART interface
The target MCU has a USART module, which can be accessed using its Flexcomm
modules 0-7. In the LPCXpresso55S36 board, the USART module is accessed using
Flexcomm modules 0 and 2 of the target MCU.
The figure below shows the USART connection diagram of the LPCXpresso55S36 board.
