# HPM5301EVKLITE
2+
3+
## Overview
4+
5+
HPM5301EVKLite is a development board based on Xianji's entry-level high-performance MCU HPM5301. HPM5301EVKLite provides a USB Type-C interface for high-speed USB-OTG functionality, with onboard buttons and LEDs for convenient user interaction. It also provides an extension interface that is compatible with Raspberry Pi and a standard JTAG debugging interface.

## Console information printing
10+
11+
By default, UART0 is used for console printing. Connect UART0.TXD (J3.36) and UART0.RXD (J3.38) externally through the USB to serial port tool.
12+
13+
## Boot Switch
14+
15+
- KEY&BOOT controls boot mode
16+
17+
Note：
18+
- The default working mode is flash boot mode.
19+
- Follow the below steps to enter ISP boot mode:
20+
1. press reset
21+
2. press key
22+
3. release reset
23+
4. release key
24+
