Would you consider other single board computer besides raspberry pi for this? There are many alternatives with much better graphics support, and more powerful. These make a lot nicer chart plotter.
Hi Sean,
I am not sure. The TI chip is 18 years old so i am pretty sure there is a reason they
added a thermal pad to the tqfp100 package. I will order one of the pcbs from Farnell
to test the chipset together with the display before developing my own pcb.
Regarding other single board computers, if they are available in a similiar board factor
like the RPi compute module it can be done. I will start with the RPi because i already
bought two modules, the development board and some parts like DIMM socket and
SD-Card socket.
