The NuMaker-M2L31SG is an evaluation board for Nuvoton NuMicro^® M2L31SG4AE, M2L31XD4AE, M2L31ZE4AE, M2L31ZD4AE, M2L31YG4AE, M2L31YE4AE, M2L31YD4AE, M2L31LE4AE, M2L31LG4AE, M2L31LD4AE and M2L31SE4AE  microcontrollers. The NuMaker-M2L31SG consists of two parts: an M2L31SG  target board and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-M2L31SG is designed for project evaluation, prototype development and validation with power consumption monitoring function.

The M2L31SG target board is based on NuMicro M2L31SG4AE. For the development flexibility, the M2L31SG 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.
