Robo-Tank PCA9685 Expander DIY
Get more out of the Robo-Tank Deluxe controller using this PCA9685 expander. It has 16 outputs on two DB9 sockets and connects to the I2C port on the controller. It allows you to connect Robo-Tank AC power bars freeing up the DB9 sockets on controller for the other extenders available.
Note: This is a DIY kit and requires soldering the through hole parts in the image. (assembly manual coming soon but it's straight forward)

3D Printed Case
I've designed a case to house the extension that you can 3D print yourself or order one on the right side of the page. If you purchase a case there many be small defects due to 3D printing but any will be minor and only have a visual effect.
