I will design custom pcb and schematic for arduino, esp32, and stm32

I design custom PCB schematics and layouts around Arduino, ESP32, STM32 and other embedded controllers, taking your project from breadboard, development board or circuit concept to a board that can be fabricated and assembled. The design is developed around your interfaces, power requirements, dimensions, components and chosen PCB manufacturer.

WHAT I DESIGN

• Arduino, ESP32, STM32 & custom MCU boards
• Complete schematic capture and PCB layout
• Sensors, displays, relays, motors and actuator circuits
• Wi-Fi, BLE, USB, CAN, RS485, UART, SPI & I2C interfaces
• Battery charging, regulators and protection circuits
• SWD, JTAG, ISP, USB & UART programming/debug headers
• Single, double or multilayer PCBs

ENGINEERING CONSIDERATIONS

• Ground planes, decoupling and power distribution
• EMI-aware placement and signal routing
• RF antenna placement & keep-out areas
• Current-rated traces, thermal design and test points
• Differential/impedance routing where required
• DFM/DFA checks for fabrication and assembly

MANUFACTURING DELIVERABLES

• Editable schematic + PCB source files
• Gerber + NC Drill package
• BOM with part numbers
• Pick-and-Place/Centroid file
• PDF schematic + optional STEP/3D board model

NDA available.
