Hi guys
I'm having a first proper go at designing a two sided PCB and would appreciate someone having a look at the ground plane to see if it will be sufficient, though it should be noted that I'm still tinkering with it so the pic below doesn't represent it's finished state.
The system is mainly analogue, with digital only playing a part for ISP purposes, at which point the analogue circuits won't be active.
I'm still getting to grips with proper component placement on the top layer though, so the majority of analogue circuits have ended far left, with a 3w amp plonked far right, so my idea was to create an island for the analogue return currents to play in that was separate from power ground and then connect both at a single point to the battery's negative terminal port in the hope that this would prove a sufficient.
