With a clear conscience I had to revise my original review. The board works well except for the LED which is reversed so 4 star rating. The reason the board didn't work for me was that I misinterpreted the I2C address. I used a decimal value, not hexadecimal. my fault By the way, the LED does not affect the operation of the board. I could fix it, but it's not worth the trouble.
