Possibly, sometimes, under some conditions. Some credits to Nick Gammon, I've used his schematics as a reference (especially on the TX enable pin, which was quite smart, using only 1 pin).ĮDIT: It's better not to use a pull-up resistor on the reset line. Would be nice to give me some credits/donation, but you can freely use it for even commercial projects. Doesn't it need any resistors? I've seen some on the RS485 breakout boards.Can I actually use the RESET pin as other functions (without changing fuse bits)?.It says: 36mm by 15mm isn't this too small to fit all those components?.Are the rounded-off traces actually better as sharp edges?.Should I use a copper/ground fill? Which and why?.Is the spacing of the board/lines to other components/side big enough?.Some points of which I'm unsure, or might be a problem: I would be using SoftwareSerial since the ATTiny does not have serial (Rx/Tx). Now I'm unsure if the PCB would work, as this also is my first try in PCB design. I don't yet have the components, so I haven't actually tried it on a breadboard. I've designed an PCB and due tot the delivery times, I kinda want to order it right now.
