ESP32 firmware & PCB design

$10/hr Starting at $50

Need ESP32 firmware that actually works? I deliver production-ready code, not experiments.

I develop ESP32 firmware for IoT devices with WiFi, Bluetooth, and cloud connectivity. Smart home devices, industrial sensors, or custom IoT productsI handle it all.


WHAT YOU GET:

ESP32 DEVELOPMENT:

C/C++ firmware using ESP-IDF or Arduino framework, WiFi with auto-reconnect, Bluetooth Low Energy for mobile apps, LoRa for long-range, multi-sensor integration (I2C, SPI, analog, UART)


IoT CONNECTIVITY:

MQTT protocol with TLS security, HTTP/HTTPS REST APIs, WebSocket real-time data, OTA firmware updates, ThingsBoard or Blynk dashboards, AWS IoT Core integration, Firebase database, custom backend APIs


PCB & GERBER FILE: 

I provide complete, production-ready PCB layouts and Gerber files ready for manufacturing


CODE QUALITY:

Fully commented source code, FreeRTOS task management, error handling and recovery, low-power sleep modes, memory optimization, watchdog timers


ADVANCED FEATURES:

Modbus RTU protocols, RS485 communication, multi-device coordination, secure boot and encryption, bootloader customization


SUPPORTED BOARDS:

ESP32, ESP32-S2, ESP32-S3, ESP32-C3, ESP32-C6
