Nuvoton's NuMaker-IoT-M263A Development Board Packs Three Radio Modules for IoT Power

With Wi-Fi, Bluetooth Low Energy, and LoRa coverage, the NuMaker aims to be an all-in-one development board for Internet of Things projects.

Nuvoton has launched a development board that aims to cover as many Internet of Things (IoT) communication protocols and standards as possible in a single unit: the NuMaker-IoT-M263A.

"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," the company explains. "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-related products and easily program and debug applications."

The primary microcontroller on the board, brought to our attention by CNX Software, is Nuvoton's own NuMicro M263KIAAE, an Arm Cortex-M23 running at 64MHz with 96kB of static RAM (SRAM) and 4kB of LDROM. This is then connected to not one but three independent wireless modules: an Espressif ESP12-F ESP8266 802.11b/g/n module; a Raytac MDBT42Q-PAT Bluetooth 4.2 and 5.0 Low Energy (BLE) module; and an Appcon APC1278 LoRA radio for 408MHz, 433MHz, and 470MHz bands.

The board also includes a BME680 air quality sensor, BMX055 nine-axis accelerometer, CAN bus, RS485, mini-PCIe socket with SIM connector for cellular modems, and Arduino Uno-compatible pin headers for add-on Shields. A microSD slot provides additional storage, while each portion of the system can be powered off using physical switches.

The board is now available to order from Nuvoton Direct, priced at $100 in single-unit quantities.
