STATUS UPDATE: Nokia LCD backpack

in Status update by Ian | 3 comments

We’re trying a new Monday post with status updates on new projects currently in production. This will cover project development, and gritty details like last minutes changes and production problems.

This is a simple USB backpack for SparkFun’s cheap color LCDs. A PIC 18F24J50 controls the LCD from a USB connection, and a small booster steps the ~5volt USB supply to 7volts.

Demo firmware and utility are now available. Our example uses a simple USB->serial interface, but HID and other device types are possible.

Production was stalled for months because we couldn’t find a suitable LCD supplier. Eventually we asked SparkFun and they shared a source (Thanks SparkFun!). It is in production now and should be available in a few weeks.

    Nice as casebadge for modders. What are the dimensions?

    Um, mounting holes?

    I’ve used the SFE breakout board in a couple of projects, and both times I mounted the LCD to a motherboard with some stand-offs. I don’t see any holes in the PCB for mounting this board – how do you expect to place it in a finished enclosure?

    Even for the crudest prototypes it’s useful to have some way to mechanically stabilize the display.

      Amateurs! :) It really is a disappointment. We always use mounting holes and breakout extra pins now, but this was a really old project from back when we weren’t so good at that. It was stalled for lack of screens, but the hardware was ready. This one will be super cheap first revision, any second revision will have the updates.
