adafruitss Class Reference

API for the Adafruit Servo Shield. More...

Detailed Description

• ID: adafruitss
• Name: Adafruit Servo Shield
• Category: servos
• Manufacturer: adafruit
• Link: http://www.adafruit.com/product/1411
• Connection: i2c

UPM library for the PCA9685-based Adafruit 16-channel servo shield. If 3 or more GWS servos are attached, results could be unpredictable. Adafruit Industries recommend installing a capacitor on the board, which should alleviate the issue. Sizing depends on servos and their number.
