FAQ
What microcontrollers can you work with?
I work with ESP32, STM32, nRF52, RP2040 and other microcontrollers based on your project requirements.
Can you design a custom PCB from scratch?
Yes. I can create the schematic, select components, design the PCB layout and prepare manufacturing file
Can you develop the embedded firmware too?
Yes. I develop embedded C/C++ firmware, peripheral drivers, communication protocols and device control software.
Can you integrate sensors and modules?
Yes. I can integrate temperature, humidity, IMU, GPS, RFID, LoRa, Bluetooth, WiFi, Ethernet, displays and other modules.
Can you develop complete IoT hardware?
Yes. I can develop the electronics, PCB, firmware, sensors, connectivity and supporting production documentation for an IoT device.
Do you provide Gerber and manufacturing files?
Yes. Depending on the package, I can provide Gerber, drill, BOM, pick-and-place/CPL and other files needed for PCB manufacturing.
Can you work with an existing schematic or PCB?
Yes. I can review, troubleshoot, modify or improve an existing design and develop the required firmware.
Can you build a prototype based on my idea?
Yes. Send your concept, requirements, reference design or specifications and I can help develop the embedded hardware and firmware solution.
Can you help select components for my project?
Yes. I can recommend suitable microcontrollers, sensors, ICs, power components and communication modules based on your requirements.
