For development flexibility, the M3333KI target board provides extension connectors, the Arduino UNO compatible headers and the capability of adopting multiple power supplies. Furthermore, the Nuvoton-designed ammeter connector can measure power consumption instantly, which is essential for prototype evaluation.\u003c\/p\u003e\u003cp\u003eIn 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.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/NuMaker-M3333KI.png?v=1784109675\" alt=\"NuMaker-M3333KI\" height=\"275\"\u003e\u003c\/p\u003e\u003ch5\u003eTechnical Documents\u003c\/h5\u003e\u003cul\u003e\u003cli\u003eFor more details, please visit Nuvoton Official Website: \u003ca href=\"https:\/\/www.nuvoton.com\/board\/numaker-m3333ki\/index.html\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eGO\u003c\/a\u003e\n\u003c\/li\u003e\u003c\/ul\u003e","brand":"Nuvoton Direct","offers":[{"title":"Default Title","offer_id":48299242782926,"sku":"NK-M3333KI","price":30.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/1820_ecda05d8-82d2-44b7-8d9a-96f1037d981e.png?v=1784109704"},{"product_id":"numaker-m3334ki","title":"NuMaker-M3334KI","description":"\u003cp\u003eThe NuMaker-M3334KI is an evaluation board for Nuvoton NuMicro\u003csup\u003e®\u003c\/sup\u003e M3334 series microcontrollers.
