These weeks I have been working on a revision of the IceNav PCB
The idea is to minimize as much as possible and use TFT in parallel mode and not SPI in order to obtain maximum performance at the graphic level.
The PCB design is ready, but it remains to be seen whether the appropriate tests can be carried out and whether a good enough design can finally be achieved.
Until we have a physical PCB and can perform the corresponding tests, the PCB design would be something like this:
This is a first revision, the idea is to be able to integrate modules such as battery charging, sensors, etc... without using existing modules, but I think it's a good start...
