Tips and tricks

I think JLCPCB has saved our (engineering) life many times!!!

I'm addicted now.

Modular circuits; a CD jack on the right with a 7805 voltage regulator. I bought a bunch of breadboards over on amazon, so I just leave them on the breadboard and can quickly test something related with "power". Just make sure your pins are spaced like on your breadboards (2.54mm usually).




Tip #1: I sacrificed my worst breadboard and use it to solder my modules. That way the header pins are always perfectly straight.

Tip #2: Instead of using double-pins cause singles are annoying to hold (like on my DC jack module), use a full-length header but remove the unneeded pins (7805 module):




Tip#3: you can determine where JLCPCB puts their order # on your PCB, just add JLCJLCJLCJLC wherever you want (see bottom of 7805 module above).
