BinaryRock

Going to roll the dice on having boards made without prototyping it first. I have no idea if this will work but I think I thought it through well. First version is single frequency and set using binary instead of ordering it programmed to a set of frequencies.

Whatever frequency you want, convert the Hz to binary and solder it on the back. I have the parts on the way and I'll be ordering boards tomorrow after I triple check everything. Board is 30mm x 34mm and the output can be direct from the 5351 output, or by turning a resistor 90 degrees, passed through a mosfet at supply voltage (input voltage, not the 3.3v regulator). Should make the output strong enough to work the neighbors. Still contemplating resistor choice there.

This will be my first 4-layer board. I have a few little changes to make but this is about what it will look like. 6-pin header for initial programming only. Power in the 2-pin header.

Edit with updated board views. Ordered today.

That is exceptional! Fingers crossed it all works the first production run.

Thanks! I sure hope it works because shipping alone hurt so bad ($106) that I ordered 1000 boards instead of 100 so I didn't have to order again. Wasn't much difference in shipping.

The schematic makes sense (to me anyhow) and DRC showed no errors but I'm definitely crossing my fingers anyhow because I am $380 total into those boards now.

I guess if these don't work, I'll drill holes in the corner, add a key ring, then drop them off at the local gas stations lol. Nice thing about livin' in the woods, everyone does consignment around here. Ain't like a Kwik Trip with a corporate office. I'll still make it work even if they fail.

Kinda wish I hadn't put my call sign on the silkscreen now.
