Most Helpful Review
"This is a great board. It works identically to my old Arduino UNO. I noticed an extra blob of solder on my board but it doesn’t seem to create any short circuits and even if it did, I can use my soldering station to remove it. I can see how this would be a problem for those who aren’t into soldering but for me, being able to achieve the same functionality as the Arduino UNO for cheaper is worth it. I’d buy this again."
