• Looks great!

    Just some ideas:

    • those holes under the Pico will make it very difficult to solder a castellated Pico right onto the board - I guess you could just stick some tape under it to insulate it though?
    • is there a cut-out in the board to allow a Type A USB socket to slide over the Pico? Looks like you've stopped the ground line there but the actual PCB outline goes straight on. Again, not an issue if you're mounting the Pico on pins, but if you want to solder it straight down it'd be a pain (and soldering it straight down is really handy).
    • I don't know if you care, but you could swap all your square vias to be round with the 'Change' tool.
    • I'm not sure where you'd put them, but what about mounting holes? A lot of people complained about that with Espruino, and I can see that you might want to screw it into a box
    • Finally, I don't know whether there are 'standard' box sizes, but if there are, you might be able to tweak the PCB size slightly so it'll easily fit into a project box?

    Looks like I'll probably start some kind of online shop for the adaptor shims, so I'd be very happy to sell this with some kind of referral?

    About the 45 degree angles - I still think it's a non-issue for normal GPIO lines (I imagine it helps stuff like clock lines). But yes, it won't stop people complaining whenever they see one :) I still want a PCB design tool that'll do routing with nice curved lines that automatically bend around vias and things.

  • Holes under pico: They're there to make it more useful if you're not using a pico. My intent was for people to put tape there to insulate it when soldering it directly on.

    Space for USB - Yipes! Good catch. I just removed all the exposed ground from that 1.2" section, and slid everything over 0.1", so, if you wanted people to laugh at you, you could plug the whole damned board into your USB port (assuming it's not recessed).

    What square vias? <.< >.>

    Mmmm.... Mounting holes... I'm not really sure where I could put them either!

    I've seen no evidence of sizes of project boxes being standardized. They can't even decide whether to measure outside or inside.

    @Gordon - we should probably talk about selling via PM/etc? I'm going to ebay a few of my initial protos, and see how they fly, and how much of a pain it is to ship them out. I think i might be able to just put them into envelopes and mail em like letters (at least w/in the US), in which case I'll probably be selling these, or at least the other version.

    I will pull the trigger on a protopack of these in just a couple of hours - last chance to call out problems :-) I will have them shipped by a less-shitty shipping method, so I should have them in hand in a non-horrible length of time.
