The NuMaker Uno is a specific development tool for NuMicro® Cortex®-M0 series by which users can develop and verify the application program easily. The purpose is to provide a set of development and learning of both packages, with ADC, PWM, I²C, SPI, etc. peripheral functions, users can replace NuMaker Uno development kits with different functions can also be based on user needs its own peripheral functions development Kit, easy to use and yet develop the required flexibility. The NuMaker Uno includes two portions: evaluation board and Nu-Link debugger/programmer. The Nu-Link is also included so users do not need additional ICE or debug equipment.
Features
Learning / Applications / debug: full range of development tools
Easy to carry the development debug kit
