The NuMaker-M251KG also provides an ammeter connector, allowing user to monitor the microcontroller’s power consumption during development.\u003c\/p\u003e\u003cp\u003eThe 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-M251KG, allowing user to use as a mass production programming tool.\u003c\/p\u003e\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/NuMaker-M251KG.png_896832344.png?v=1779182109\" alt=\"NuMaker-M251KG\"\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-m251kg\/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":43529171960014,"sku":"NK-M251KG","price":25.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0664\/0749\/7934\/files\/1324.jpg?v=1779182123"}],"url":"https:\/\/direct.nuvoton.com\/collections\/m251-m252-series.oembed","provider":"Nuvoton Direct","version":"1.0","type":"link"}
