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.
