The NuMaker-ML54SD is a development board for Nuvoton NuMicro® ML54 series microcontrollers. The ML54 series is the first of NuMicro® 8051 series integrated with LCD controller function. The NuMaker-ML54SD platform consists of three parts: an ML54 evaluation board, an on-board Nu-Link2-Me debugger and programmer, and a HTN-LCD panel module. The NuMaker-ML54SD is designed for project evaluation, prototype development and validation with power consumption monitoring function.

The ML54 evaluation board is based on NuMicro® ML54SD1AE. For the development flexibility, the ML54 platform provides the extension connectors of ML54SD1AE, the Arduino UNO compatible headers and able to adopt multiple power supply. Furthermore, the Nuvoton-designed ammeter connector can measure the power consumption instantly, which is essential for the prototype evaluation. The NuMaker-ML54SD provides 8 x 28 COM/SEG LCD display function. With the HTN-LCD panel, user can implement LCD display function of ML54SD1AE easily.

In addition to the ML54 platform, 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 development board and becoming a stand-alone mass production programmer.
