NUMAKER-M263KI USER MANUAL
Maker Nu-mbed NUC472 User Manual
1 OVERVIEW
This user manual is aimed to give users a fast introduction to the use of NuMaker-M263KI board.
The NuMaker-M263KI consists of two parts, a M263 platform and an on-board Nu-Link2-Me debugger
and programmer. The NuMaker-M263KI allows users to quickly develop and easily program and
debug application.
The NuMaker-M263KI offers M263KIAAE full pins extension connectors, Arduino UNO compatible
extension connectors and diversified power supply option. It is an easy-to-develop platform for user to
expand the functionality and build the applications. The NuMaker-M263KI also provides an ammeter
connector, allows user to monitor the microcontroller’s power consumption during development.
The Nu-Link2-Me is a debugger and programmer that supports on-line programming and debugging
through SWD interface. The on-board 16 Mbit SPI Flash allows it to off-line program the target
microcontroller. The Nu-Link2-Me provides virtual COM port (VCOM) function to print out messages
on PC. The Nu-Link2-Me can be separated from NuMaker-M263KI, allowing user to use it as a mass
production programming tool.
