How are modules with flat connectors typically connected? (If they have a special name, please tell me). Take a look at this buck converter:
When testing, I just used crocodile clamps. Now I want to go to "production" and something more permanent and at the same time modularity is needed. What is the industry standard? Up to 3 A will flow through the module.
The wire I had was too thick to go through the hole so I just put it in horizontally.
I had to switch from lead-free to leaded solder, because that silver stuff was terrible to work with.
