PSOC3 custom board development

Posted on Saturday, December 3rd, 2011 in project logs by DP

We wrote about Kmmankad effort to build a custom PSOC3 development board. After the initial design, he consulted Cypress engineers about his board. They advised him how-to improve his design. Here are the latest revisions:

  • Added additional vias between the top and bottom layers to improve return paths.
  • Crystal routing improved(Capacitors on same side,traces shorter).
  • Added reverse polarity protection diode across Unregulated DC Input(VIN).
  • Added Fuse to USB supply.
  • Added LED for Bootloader Status.
  • Widened Power tracks for better stability.
  • Differential Routing for SWD and USB tracks.
  • Changed back to Type B USB connector,easier to solder.

It is pretty cool to see the industry help out DIYers.
