I will make iot hardware and firmware node for you lora ble lte nbiot mqtt

Need expert IoT development to transform your concept into a secure, scalable product? I deliver end-to-end IoT development with robust firmware project, reliable cloud integration, optimized PCB design, and seamless ESP32 integration for commercial deployment.

With 5+ years of professional IoT development, I build industrial-grade systems using ESP32, ESP8266, STM32, Arduino, Raspberry Pi 5, LILYGO, Heltec, TTGO, SIM800L, SIM7600G, A7670G, and SX1276/77 LoRa. My firmware development (C/C++, MicroPython) ensures stable ESP32 integration, secure MQTT/HTTP/Modbus communication, and scalable cloud integration via AWS IoT Core, Azure IoT, Firebase, Mosquitto, Blynk, ThingSpeak, and Adafruit IO. Every PCB design supports reliable IoT development from prototype to production.
