| Hi, I am wondering if there is any means of digital output other than the motor ports such as the miniboard has. The miniboard has the bank of digital i/o ports. The handyboard has the digital input but I am not sure about digital output other than (...) (29 years ago, 29-Mar-96, to lugnet.robotics.handyboard)
