The NuMaker-M051L is an evaluation board for Nuvoton NuMicro M0516LDN, M0516ZDN, M052LDN, M052ZDN, M054LDN, M054ZDN, M058LDN, and M058ZDN microcontrollers. The NuMaker-M051L consists of two parts: an M051 target board and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-M051L is designed for project evaluation, prototype development and validation with power consumption monitoring function.

The M051 target board is based on NuMicro M0516LDN. For the development flexibility, the M051 target board provides the extension connectors, the Arduino UNO compatible headers and the capability of adopting multiple power supplies. Furthermore, the Nuvoton-designed ammeter connector can measure the power consumption instantly, which is essential for the prototype evaluation.

In addition, there is an attached on-board debugger and programmer “Nu-Link2-Me”. The Nu-Link2-Me supports on-chip debugging, online and offline ICP programming via SWD interface. The Nu-Link2-Me supports virtual COM (VCOM) port for printing debug messages on PC. Besides, the programming status could be shown on the built-in LEDs. Lastly, the Nu-Link2-Me could be detached from the evaluation board and become a stand-alone mass production programmer.
