The NuMaker-M258KG is an evaluation board for Nuvoton NuMicro M258KG and M258SG microcontrollers with COM/SEG LCD driver, USB 2.0 FS device and capacitive touch key sensing function. The NuMaker-M258KG consists of two parts: an M258KG target board and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-M258KG is designed for project evaluation, prototype development and validation with power consumption monitoring function.

The M258KG target board is based on NuMicro M258KG6AE to evaluate the capacitive touch key sensing function on TK14 with message display on 8 x 40 HTN-LCD panel for Human Machine Interface application. For the development flexibility, the M258KG 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.
