Tilemap PCB (Fix!) - VGA from Scratch

Uploaded July 2022 | Updated September 2026, 1 week ago

I really wanted to fix the tilemap pcb before I moved on, some of the future circuits are going to be based on it so a fully working circuit was a must. I start by resolving the bit order issue in the schematic and pcb, additionally I add some extra ground connections which are something that I think I need to pay more attention to.

I recently bought a soldering hot plate, this is the first full PCB using it.
