Future JeeNodes – thoughts

In AVR, Hardware on May 19, 2009 at 00:01

After several months tinkering with the JeeNode v2 boards, I’m starting to make a list of things I’d like to change for a future design.

What I’d like to keep:

  • having 4 identical “ports”, both physical and in software
  • running at 3.3 V, with on-board regulator
  • the wireless radio module :)

What I’d like to change:

  • switch to SMD to create a smaller unit
  • add a PCB antenna, even though it’s frequency band specific
  • add mounting holes

This could perhaps become the layout:

Not 100% sure about the SPI/ISP and I2C/PWR pin headers – though I’m inclined to keep them, somehow.

No idea when or even whether this ever materializes, just some thoughts.
