FAQ
Which microcontrollers do you support?
I work with ESP32, STM32, Arduino (AVR), and other ARM-based microcontrollers. I can also support custom boards if documentation is provided.
Can you write firmware using FreeRTOS or Bare Metal?
Yes! I have hands-on experience with FreeRTOS, bare-metal coding, and HAL-based development for both STM32 and ESP32.
Do you offer support after project delivery?
Yes, I provide ongoing support and code explanations even after delivery. Clean, well-documented code is part of my service.
Can you help me choose the right hardware for my project?
Of course! I can recommend the best microcontroller, modules, and components based on your project needs and budget.
Do you offer PCB design or just firmware?
I can do both. I offer schematic and PCB layout reviews or full custom board design using KiCAD, Altium, or Eagle.
Can you help with OTA (Over-the-Air) updates or bootloaders?
Absolutely. OTA, bootloaders, and firmware encryption are available in my advanced packages.
