NUMAKER-MS51PC 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-MS51PC board.
The NuMaker-MS51PC consists of two parts, a MS51 platform and an on-board Nu-Link2-Me debugger
and programmer. The NuMaker-MS51PC allows users to quickly develop and easily program and
debug application.
The NuMaker-MS51PC offers MS51PC0AE 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-MS51PC 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 support on-line programming and debugging
through OCD 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-MS51PC, allowing user to use as a mass production
programming tool.

4. Connect ICEJ3 to PC.
5. Connect the external power supply to JP1.
To use Vin or J2 as external power supply source with Nu-Link2-Me separated from NuMaker-MS51PC,
please follow the below steps:
1. Switch the SW2 depends on the target chip operating voltage.
2. Separate the Nu-Link2-Me from NuMaker-MS51PC.
3. Connect the external power supply to Vin or J2.
To use JP1 as external power supply source with Nu-Link2-Me separated from NuMaker-MS51PC,
please follow the below steps:
1. Switch the SW2 to OFF.
2. Separate the Nu-Link2-Me from NuMaker-MS51PC.
3. Connect the external power supply to JP1.

Note:
1. The Vin input voltage will be converted by voltage regulator UP2 to 5 V.
2. 0Ω should be removed from ICEJPR1’s MCUVCC and 1.8 V / 3.3 V / 5 V.
3. 0Ω should be soldered between ICEJPR2’s ICEVCC and 1.8 V / 3.3 V.
4. The ICE chip voltage should be close to the target chip voltage.
5. JP1 external power input only provides voltage to target chip. Supply external power to Vin or J2 can provide
5V to NU1 pin5 (5V) and 3.3V to NU1 pin4 (3VCC).
