None of these IOIOs seem to be from any manufacturer I know. I have no idea what they did there. According to your explanation, somebody might have tried to be smart with the inductor and messed something up in the circuit. I recommend you to consider buying from SeeedStudio or SparkFun, where I verified that they are using only high quality parts and testing each and every board thoroughly.
