FAQ
Can you work with my ESP32, STM32, Arduino, or other microcontroller?
Yes. I can develop and troubleshoot firmware for ESP32, STM32, Arduino, ESP8266, and compatible embedded hardware based on your project requirements.
Can you design both the firmware and PCB for my IoT project?
Yes. I can handle firmware, schematic/PCB design, sensor integration, WiFi/BLE communication, and hardware prototyping depending on your package.
Can you fix or improve my existing embedded firmware?
Yes. Send your source code, hardware details, error logs, and expected behavior. I can troubleshoot bugs, improve functionality, and help optimize your firmware.
What do you need from me before starting?
Please provide your project requirements, microcontroller/board, schematic or PCB files if available, sensor list, required features, communication protocols, and any existing firmware or documentation.
