LPC55S36-EVK Functional Description
This chapter describes the features and functions of the LPC55S36-EVK board. You can use the functionality described in this
chapter as a reference while designing your own target board.
For details of the LPC5536 MCU features, see
LPC553x Reference Manual.
NOTE
The chapter is divided into the following sections:
• Power supplies

2.1 Power supplies
The LPC55S36-EVK board is powered up using the following primary power supplies:
• External 5 V power through USB micro-B connector J1
• External 5 V power through USB micro-B connector J2
• External 5 V power through USB micro-AB connector J3
• VIN1 (5 V max.) power from Motor 1 + unused MCU pin socket connector J10
• VIN2 (5 V max.) power from Motor 2 + Arduino socket connector J102
The primary power supplies are used to produce secondary power supplies for the board to power up other board components,
including the target MCU (LPC5536), MCU-Link, mikroBUS socket, motor control and Arduino sockets, audio codec, DMIC,
octal flash memory, high-speed CAN transceiver, push buttons, and LEDs. The figure below shows the LPC55S36-EVK power
supply diagram.
