FAQ
Do you provide hardware recommendations?
Yes! If you're unsure which microcontroller to use (ESP32 vs STM32 vs nRF52), I'll recommend the best platform based on your project's power, connectivity, and cost requirements.
Can you work with my custom PCB?
Absolutely! Just provide the schematic/circuit diagram and component datasheets, and I'll develop firmware specifically for your hardware.
What if I need changes after delivery?
Standard and Premium packages include free post-delivery support. Additional revisions can be ordered as gig extras if needed.
Do you test the code on real hardware?
Yes! For Standard and Premium packages, I test on actual hardware (ESP32/STM32/nRF52 dev boards). For custom PCBs, I use simulation + serial debugging.
