The NuMaker-IoT-M2354 board combines the secure NuMicro M2354 MCU with Wi-Fi, LoRa, sensors, and LCD for rapid IoT prototyping. Running Mbed OS with a prebuilt app, it measures pressure, temperature, and humidity, displays results locally, and uploads data to AWS via Wi-Fi. With Arm TrustZone, TF-M, and NuCloudConnector support, it delivers hardware-enforced security, encrypted cloud connectivity, and simplified device monitoring for IoT applications.
