The boards measure 56×47 mm and support a range of IoTsmart MCU modules based on Raspberry Pi RP2350, ESP32-S3, Seeed Studio XIAO, and others. Software support includes the IoTflow no-code framework for MQTT and Node-RED, plus Blynk, Tasmota, and Home Assistant integration. Target use cases span industrial automation, industrial IoT, smart agriculture, and smart home applications. IoTsmart modules are priced $7–$10 and IoTextra Octal boards run $15.50–$21. ## Full article daily.dev links to this article rather than hosting it.
