FAQ
What do I need to provide before placing an order?
You should share your project requirements, hardware details (Arduino/ESP32 model, sensors, modules, etc.), and any specific functions you want. If you already have a circuit diagram or partial code, that will help too.
Do I need to ship my hardware to you?
No, that’s not necessary. If I have the same module, I can test it directly. If not, I’ll guide you step by step to test the code on your setup.
Can you also help me with circuit design or hardware issues?
Yes! I can guide you with wiring, pin connections, and basic circuit design. If needed, I can also suggest compatible sensors, modules, and components for your project.
What kind of projects do you work on?
I work on custom electronics projects including PCB design, circuit schematics, STM32/ESP32/Arduino firmware, sensors, motor control, IoT devices, and prototype development.
