## Product: "ESP32 Expansion Board 3 Pack"
**Brand:** DIYables

## Pros
- Fits perfectly with 38-pin ESP32-DevKitC_V4 and compatible with NodeMCU-32S, ESP-WROOM-32D/32U, and ESP-WROVER models.
- Solder-free design makes connection straightforward and hassle-free.
- Multiple power input options add flexibility for various projects.
- Comes in a 3-pack option, handy for multiple developments or backup boards.
- Handy little development board for powering individual pins and basic use cases.
- High-quality build and reliable performance according to user feedback.
- Users who have tried it would choose it again without hesitation.

## Cons
- The 3-pack option is not the default; buyers must specifically select it, which can be confusing.
- Communication about what comes in the default purchase is unclear and can mislead customers expecting three boards.
- Limited testing reported by some users—uncertainty remains around full functionality in more advanced projects.

## Bottom Line

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.
