NuMaker-IoT-M263AAug 06, 2019 Page 7 of 50 Rev 1.00NUMAKER-IoT-M263A USER MANUALM -m U1 OVERVIEWThis user manual is aimed to give users a fast introduction to the use of NuMaker-IoT-M263A board.The NuMaker-IoT-M263A consists of two parts, a M263 platform with on-board modules, and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-IoT-M263A allows users to quicklydevelop IoT (Internet of Thing) application and easily program and debug application.The NuMaker-IoT-M263A offers M263KIAAE with Arduino UNO compatible extension connectors anddiversified power supply option. It is an easy-to-develop platform for user to expand the functionalityand build the applications. The NuMaker-IoT-M263A also provides an ammeter connector, allows userto monitor the microcontroller’s power consumption during development.The NuMaker-IoT-M263A contains several common kinds of wireless modules, like Wi-Fi, Bluetoothand LoRa. The NuMaker-IoT-M263A also supports a mini PCIe connector. User can use othermodules, such as NB-IoT, 3G/4G, GPS. Besides, the NuMaker-IoT-M263A supports CAN and RS485transceiver to make user develop industrial IoT application. Furthermore, the NuMaker-IoT-M263Aequips an environmental sensor and a 9-axis sensor for user application.The Nu-Link2-Me is a debugger and programmer that supports on-line programming and debuggingthrough SWD interface. The on-board 16 Mbit SPI Flash allows it to off-line program the targetmicrocontroller. The Nu-Link2-Me provides virtual COM port (VCOM) function to print out messageson PC. The Nu-Link2-Me can be separated from NuMaker-IoT-M263A, allowing user to use it as amass production programming tool.Figure 1-1 NuMaker-IoT-M263A Board
