FAQ
Can you design both hardware and firmware?
Yes. I provide complete PCB design, schematic capture, embedded firmware, and production-ready files.
Which microcontrollers do you support?
STM32, ESP32, AVR, PIC, ARM Cortex-M, Nordic, and many other embedded platforms.
Can you implement Modbus RTU?
Yes. I develop complete Modbus RTU slave and master firmware with reliable RS485 communication.
Can you design isolated RS485 interfaces?
Absolutely. I can design isolated RS485 communication circuits with surge protection and industrial-grade reliability.
Which software do you use?
Altium Designer, KiCad, EasyEDA, Cadence Allegro, and embedded development tools such as STM32CubeIDE, ESP-IDF, PlatformIO, and Keil.
Will I receive editable files?
Yes. You'll receive the original design files, source code, Gerbers, BOM, and manufacturing documentation.
