Adafruit 16 channel servo driver
Hello, I have 2 Adafruit 16 channel servo driver boards chained together. One is address 0x40 the second is configured as 0x41. When I run a I2C bus scan program the second board shows up as address 0x41 and 0x70. I've tried replacing it with another board, which produces the same results. I'm able to drive servos with board one, but not board 2. Any suggestions would be great.

Re: Adafruit 16 channel servo driver
Address 0x70 is the 'all call' address for the PCA9685. All boards will respond to that.
If you post your code and some photos showing all your soldering and connections, we can take a look.
