Moogle was disappointed by his new Arduino Uno. He thought it was pretty unrefined: rough edges, thin solder mask, poorly aligned headers. Arduino responded directly that this is an isolated incident. They will replace any less than perfect hardware. (A Moogle followup post) Additionally, bongobat may have encountered a major...Tags: Arduino Uno, green label, manufacturing problems
