![]() 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. The NuMaker-IoT-M263A provides popular wireless connectivity modules that used in IoT applications, include Wi-Fi, Bluetooth and LoRa modules. M263KIAAE based on Arm® Cortex®-M23 core.Its low-power and high-performance connectivity features strengthen the innovation of IoT. Furthermore, the M263 series also provides high-performance connectivity peripheral interfaces such as UART, SPI, I2C, GPIOs, USB and a 3.76 MSPS ADC for sensing data from sensor devices to fulfill a variety of application scenarios. The operating voltage is from 1.8 ~ 3.6V and operating temperature range is from -40℃ ~ +105 ℃. USB interfaces: MSC/VCOM/HID_ICE(proprietary commands) or CMSIS-DAPv2 WinUSB + WebUSB CMSIS-DAP/VCOM_Nu-Link2-Bridge or HID_ISP (defined by BRIDGE-MODE of NU_CFG.The NuMicro® M263 series is based on Arm® Cortex®-M23 core for Armv8-M architecture, it is a low-power microcontroller platform and could run up to 64 MHz with 512 Kbytes embedded Flash memory and 96 Kbytes embedded SRAM.Support NuMicro 8051, offline programming, encryption during data transmission, unlimited flash break points, NuMicro chip-specific features (config0/config1 dataflash setting, KPROM, etc.).Set CMSIS-DAP=0 it will disable CMSIS-DAP and enable the Nu-Link2 "USB BULK_ICE" interface (it's faster than "USB HID_ICE").Ĭomparison of NuLink2FW.bin and NuLink2_DAPLink.bin NuLink2FW.bin.It has a WebUSB interface conforming to the CMSIS-DAP protocol, and you can connect to KEIL Studio Desktop/Cloud via this interface. Set CMSIS-DAP=1 this is the default setting.If you use Nu-Link2-ME, it doesn't support BRIDGE functions, and you will only see the CMSIS-DAP option.This USB HID interface doesn't pass through data, it communicates with ISPTool via HID_ISP and offers I2C/SPI/RS485/CAN interfaces for ISPTool. Set BRIDGE-MODE=2 a USB HID interface that supports ISPTool will be enabled. (You will see a "Nu-Link2-Bridge Virtual Com Port" in device manager.) ![]() Nu-Link2-Bridge pass-through the data between the VCOM port and I2C/SPI/RS485/CAN interfaces. Set BRIDGE-MODE=1 the pass-through bridge function of Nu-Link2-Pro will be enabled (The word Nu-Link2-Bridge will be used to represent the pass-through bridge application on Nu-Link2-Pro adapter). Note that CMSIS-DAP will be disable in other BRIDGE-MODE (Limited USB endpoints). Set BRIDGE-MODE=0 this is the default setting. Set POWER-MODE for SWD output voltage level (mainly for CMSIS-DAP interface use) You need to re-plug in the USB cable to activate the setting.
