The PCA9956B is a 24-channel I2C driven constant current LED driver with PWM. I’m going to be experimenting with this IC, but don’t have any suitable breakout boards, so have knocked together a breakout board for this HTSSOP-38 package.

The breakout board is available to order on OSH Park below:

The datasheet recommends the corner pins (1, 19, 20, 38) have larger pads, presumably to help with wave soldering. The IC also has a ground pad underneath which is included on the breakout board.
