🤖 Teyleten Robot Nano I/O Expansion Sensor Shield Module for Arduino UNO R3 Nano V3.0 / Nano Pro - Compatible with UNO R1 Duemilanove 2009 (Pack of 3) Review

Easily adds a "battery powered" option to Arduino Nano circuits and allows you to use UNO style shields. Noce product for the price.

Soldering quality is terrible, some components are badly soldered: LEDs, some connectors. I press the corners a little, it's starting to work, but after a few minutes it looks like it's broken again. I really hope this is an isolated case and no one has encountered it

Will contact seller and tell them but one of the DOA. When I added the Nano, which I confirmed worked on other shields, no lights came on. I was able to connect it via USB and it worked properly for the most part, but some of the pins weren't hot. 2 out of 3 is not bad. I believe.

I like these boards for Manos as they offer more 5v and ground connections. Having to tie cables together to work with an input. While I don't take full advantage of these boards, I may use them for future plans.

I only looked closely at one of the three. I haven't seen any signs of any of the issues mentioned in previous reviews ie poor/sloppy soldering, misaligned guides. Quality looked good except for a few plastic burrs from the yellow connectors that can easily be cut off with a paper knife. The board I used worked fine; tested with power from each of the three sources; USB port; Socket and VIN pin all worked correctly. A very practical product. One with Nano for all practical purposes is…
