We just got our latest prototype back from Seeed. It looks a lot better, and this time we actually remembered to add something for scale - a British 2 pence coin (26mm dia.):
There are one or two changes over the one you'll have seen in the KickStarter page:
- Bigger and clearer markings for pin names
- A standard JST PHR-2 battery connector. Not only is this stronger, but you'll have a great selection of batteries (they're used a lot in cordless phones), and you won't have to worry about connecting the battery the wrong way around (which would be bad).
- SMD crystal and lower-profile capacitor (these are far more rugged than the previous ones we used)
- Separate LEDs (still RGB) - this may seem strange, but it means the board uses more standard parts (see below) and it's also far more obvious to beginners what each of the 3 LEDs are and how they mix to form one colour.
- Pretty much all components are from Seeed's Open Parts Library - which means that when the schematics are released, you'll be able to easily make your own PCBs without having to try and source parts from several different manufacturers.
The stretch goals are coming, but probably tomorrow - we've got to do a bit of research to see if what we want to offer you is even possible!
