NUMAKER-M2351SF 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-M2351SF board.

The NuMaker-M2351SF consists of two parts, a M2351SF platform and an on-board Nu-Link2-Me

debugger and programmer. The NuMaker-M2351SF allows users to quickly develop and easily program

and debug application.

The NuMaker-M2351SF offers M2351SFSIAAP 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-M2351SF 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 able to off-line programming the target

microcontroller. Nu-Link2-Me provides virtual COM port (VCOM) function to print out messages on PC.

Nu-Link2-Me can be separated from NuMaker-M2351SF, allowing user to use as a mass production

programming tool.
