45 bucks with the chips presoldered, it has the right chip, not some potted knock-off, a memory chip, iirc, kevin brought out a few gpio pins, spend a few couple hours stuffing a board, and you are supporting a fellow ham.

is 45 bucks REALLY going to break the bank for something that, if you can read a schematic and understand a parts list???

That's not the problem. The problem is when building larger systems, price and complexity gets out of order by a large magnitude. Re-do the maths on a three-repeater system with four remote voting sites. Also take a look at how long you are going to be sitting at the workshop bench stuffing boards. USB sound cards are three bucks each, plus the RPI3 I/O and you are DONE, at under a tenth of the price and it all just plugs in - you get to immediately work on the interesting bits rather than soldering. If chan_urd will go, you now have quite a nice voting system and xippr has already done the software for you. S
