The NuMaker-M258KE is an evaluation board for Nuvoton NuMicro M258xE, M256xE and M254xE microcontrollers with COM/SEG LCD driver, USB 2.0 full speed device and capacitive touch key sensing function. The NuMaker-M258KE consists of three parts: a 8 x 40 COM/SEG HTN-LCD panel board, an M258KE target board l and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-M258KE is designed for project evaluation, prototype development and validation with power consumption monitoring function.
The M258KE target board is based on NuMicro M258KE3AE to evaluate the capacitive touch key sensing function on TK14 pin with message display on 8 x 40 COM/SEG HTN-LCD panel for Human Machine Interface application. For the development flexibility, the M258KE target board provides the extension connectors of M258KE3AE, 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.
The Nu-Link2-Me is a debugger and programmer that supports on-line programming and debugging through SWD interface. The on-board 16 Mbit SPI Flash allows it able to off-line program the target microcontroller. Additionally, the Nu-Link2-Me provides virtual COM port (VCOM) function to print out messages on PC. Nu-Link2-Me can be separated from NuMaker-M258KE, allowing user to use as a mass production programming tool.
