The LCD carrier board for Bus Pirate prototype “Ultra” v1d went out today. This update matches the form factor of Ultra v1d (in progress) and has several minor changes:
- Uses 10 pin 0.5mm flexible PCB connector, wired to the main board with a 1:N connection. This connector is much smaller and thinner than the 1.25mm connector on v1b, it reduces the space needed between the display board and the main board.
- Flipped LCD orientation 180 degrees so font data can be written into bounding boxes in a more natural “left-to-right” orientation, eliminating the need to precalculate the text end point and write characters in reverse sequence
- Nudged the display towards the IO header. We’ll experiment with some buttons in the remaining available space
- Decoupling capacitors on LCD power pins
The 2 inch 240*320 IPS LCD display we’re been testing has a very pleasing pixel density, but we’re also itching to try the bigger 2.8 inch version. Next week we’ll send out a prototype carrier board for the bigger display, as well as some Bus Plug breakout boards.
