Amazing :shock:

First post
"In any case, it means there won't be a Bioloid wifi board for at least a month or two, assuming they come through on their promise on the UART speed, and the latency is tolerable."

Second post
"So, my "new" wifi module (from ConnectOne) has passed both tests - I can hook it up to my router and get an IP address, and I can talk to it over the serial port (using an FT232) at 1 Mbps.

I'm going to start laying out a new board for this, but it looks like the full speed wifi board is going to become a reality.

We've almost got this working with an ATmega164. I've got a new PCB coming in on Tuesday, and hopefully that will solve the problem I had with the old one.

Assuming this new PCB works, I should have this new wifi board available within a few weeks.

That's the last one - the TQFP44 layout I used was the wrong size, so I had to do a bunch of hacking on the board to try and fix it, and it still had problems with lines shorting. I also had to use an external regulator, as the SOT-223 regulator I was using couldn't hack the current draw (about 250 mA).

I've fixed the layout, and changed out the regulator for a TO-220 version, and hopefully this is just going to work.

Its taken a little longer than I originally thought - had lots of power issues, and some timing issues also.

I have a bit more software work to do - I want to implement a SYNC_READ on the onboard ATmega164, which will allow you to retrieve values from a bunch of servos with one network transaction.

Price is going to be $200 USD. They should be available on my website in a couple weeks. (http://www.huvrobotics.com)
