I will design raspberry pi cm4 cm5 pcb, carrier board, hat and custom embedded hardware

I design Raspberry Pi CM4/CM5 carrier boards, HATs and custom embedded hardware for IoT, robotics, industrial control, gateways and connected products. I can work from your idea, block diagram, reference design or existing schematic and develop a PCB around your required interfaces, power architecture, dimensions and manufacturing constraints.

WHAT I DESIGN

• Raspberry Pi CM4 / CM5 carrier boards
• HATs, GPIO expansion & interface boards
• Custom embedded, sensor & control PCBs
• USB, PCIe, HDMI, Ethernet & GPIO
• MIPI CSI/DSI, UART, SPI, I2C, CAN & RS485
• Power supplies, protection & peripheral circuits

HARDWARE ENGINEERING

• High-speed differential-pair routing
• Controlled impedance & length matching
• PCB stack-up, grounding & power integrity
• EMI/ESD and thermal considerations
• Antenna/RF keep-out requirements
• ERC/DRC + DFM/DFA verification

PRODUCTION FILES

• Schematic + editable PCB source
• Gerber + NC Drill
• BOM with manufacturer part numbers
• Pick-and-Place/Centroid
• Fabrication/assembly documentation
• STEP/3D PCB model

Tools: Altium, KiCad, EasyEDA & Fusion 360.

NDA available. Contact me with your CM4/CM5 variant, interfaces, dimensions and manufacturer requirements before ordering.
