This expansion board is a solid choice if you’re working with 38-pin ESP32 dev kits and want an easy, solder-free way to power individual pins with flexible power inputs. Just be careful when ordering to explicitly choose the 3-pack if that’s what you want, as the default purchase doesn’t include all three boards. If you want something with a similar setup but clearer packaging or more extensive testing feedback, it’s worth keeping an eye out for alternatives, but for basic, reliable expansion, this set gets the job done.
