So glad I ordered a batch of pcbs from Elecrow. The design for this pcbs is super intricate. Because we're going for a mini-sized product, there's a ton of super precise drilling that has to be done. And because it's so small, the tolerance requirements are no joke. But the manufacturing is dead-on, no mistakes at all. After we put them through all kinds of tests, every single board is working like a charm. There aren't any glitches or strange issues.
