Cheaper than Teensy

[Helder]

I've had the first revision for a few days now but haven't had time to test it out, but here it is in real life and no mockup. Plan on testing within the next couple days and of course I ordered the wrong Micro USB connectors which is why it's blank.

Man, I would love to test this thing out. It's beautiful.

Can I have one of the spare PCB's if it's possible, to test it? I have all parts needed.

Thanks

Hi all,

I'll be working on a cheap solution for programming this board via the raspberry itself in command line using avrdude and hooking up a few wires from the raspberry zero to the ISP port of the board.

This way, there is no need to buy additional ISP programmer to load the bootloader. It will be writing the bootloader, program section and fuses in one shot.

Thanks
Thanos

So like I mentioned above that version is already obsolete and I have a new one all done up, I won't be ordering it anytime soon till the one before it arrives and gets tested out. So the new version has a built in USB Hub with 4 connections (1 is already wired to the atmega) with 3 available to wire to whatever you want. Don't ask for prices as I've not looked at the overall cost of parts yet, also there will be another test phase for this version so some lucky testers will get one before everyone else when I decide to send out for testing.

Helder, can you post the schematics for the board?

It's a pam8403 circuit and arduiono pro micro circuit (freely available online) integrated into the controller pcb which is also opensource. Look for these schematics and you can build one too.

I was specifically looking for the USB hub part. I couldn't find an example online for the FE1.1s chip and the documentation for it was a bit confusing for me.

That was a tougher find but I got it from someone who tested and posted the schematic. I'll post it later when I'm home.
