Hello,
I'm an electronic designer with 25+ years of experience. I design Hardware and Firmware
Hardware:
Schematic Capture (Altium Designer), including creation of new components
PCB Design (Altium Designer):
Multilayer
3D Modelling
New Components Design
BGA, Ultra Fine Pitch and normal components
Blind, Buried and normal Vias
Clearance: 5 mils
I can send snapshots of previous work.
I've designed a Base Board for the C21 board (Merrii), based on AllWinner's A20. In that board, I've put ETH, USB WiFi/BT, 3G and some extra circuits for the application, connected via SPI.
the C21 is a castellation board. For SODDIMM boards, the system will be simpler.
Please, feel free in contact me for further details.
Best Regards,
