Board Introduction
The NuMaker-IoT-M263A developing board, is launched to speed up product design cycle with the IoT software package provided by Nuvoton, connecting the cloud of Arm Pelion, Amazon AWS, and Ali-Cloud is easy to use.
The NuMaker-IoT-M263A consists of two parts, the M263 platform with popular on-board wireless-connectivity/sensor modules, and an on-board Nu-Link2-Me debugger and programmer. The NuMaker-IoT-M263A allows users to quickly develop IoT ( Internet of Things ) related products and easily program and debug application.
The main microcontroller of NuMaker-IoT-M263A is M263KIAAE, with low power and robust security features. The NuMaker-IoT-M263A provides Arduino UNO compatible extension connectors, various power supply option and ammeter connector, makes it is easy to extend functionality and take current consumption measurement.
The NuMaker-IoT-M263A provides popular wireless connectivity modules that used in IoT applications, include Wi-Fi, Bluetooth and LoRa modules. The NuMaker-IoT-M263A also supports a mini PCIe connector for inserting external modules to realize 3G/4G/NB-IoT connectivity functions, such as QUECTEL BG96/EC21 modules. Besides, the NuMaker-IoT-M263A integrates BOSCH environmental sensor and 9-axis sensor for acceleration, geo-magnetics, gas, barometric pressure, temperature and humidity sensing. Furthermore, the NuMaker-IoT-M263A supports CAN and RS485 transceiver for industrial control application.
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 to off-line program the target microcontroller. The Nu-Link2-Me provides virtual COM port ( VCOM ) function to print out messages on PC. The Nu-Link2-Me can be separated from NuMaker-IoT-M263A, allowing user to use it as a mass production programming tool.

Quick Start
- Install the preferred toolchain. Please make sure at least one of the toolchains has been installed. - KEIL MDK Nuvoton edition M0 / M23
- IAR EWARM
- NuEclipse (GCC) ( Windows )
- NuEclipse (GCC) ( Linux )
- Download and install the latest Nuvoton Nu-Link Driver. Please install the Nu-Link USB Driver as well at the end of the installation. - Download and install Nu-Link_Keil_Driver when using Keil MDK.
- Download and install Nu-Link_IAR_Driver when using IAR EWARM.
- Skip this step when using NuEclipse.
- Download and unzip the Board Support Package ( BSP ).
- Hardware Setup - Open the virtual COM ( VCOM ) function by changing Nu-Link2-Me VCOM Switch No. 1 and 2 to ON. 
- Connect the ICE USB connector to the PC USB port through USB cable. 
- Find the “Nuvoton Virtual COM Port” at Device Manager. 
- Use the “Template” project as an example. The project can be found under the BSP folder: M261_Series_BSP_CMSIS_V3.XX.XXX / SampleCode / Template / [ GCC | Keil | IAR ]
- Open and execute the project under the toolchain. For detail setting, please refer to the NuMaker-M263KI User Manual.
- User can see the result in the terminal window on PC.
