I will design esp32, stm32, nrf or atmel pcb, schematic and embedded hardware

I offer complete embedded hardware design for projects ranging from low-power wearables and IoT devices to industrial controllers and edge gateways.

What I Can Deliver

• ESP32, STM32, nRF52/nRF53 and Atmel AVR hardware
• Circuit schematic and component selection
• 26 layer PCB design and layout
• THT/SMT component placement and routing
• RF, Wi-Fi and BLE design considerations
• Power, battery and charging circuits
• CAN, RS485, UART, SPI and I²C interfaces
• Sensor, motor-control and communication circuits
• Gerber, BOM, Pick & Place files
• PCB source files and 3D STEP models
• Hardware debugging, redesign and optimization
• Prototype and manufacturing support

Firmware & Embedded Development

• Embedded C/C++
• ESP32 / STM32 / nRF firmware
• FreeRTOS / Zephyr RTOS
• Wi-Fi, BLE, LoRa and cellular connectivity
• Sensor integration and hardware communication

Tools

Altium Designer, KiCad, EasyEDA and EAGLE

I can work from a concept, block diagram, existing schematic, reference design and develop a practical, production-ready solution.

Final pricing depends on the MCU, PCB layers, complexity, RF/high-speed requirements, firmware scope and required deliverables.
