SparkFun Bourns Absolute Encoder (EAW0J-B24-AE0128L)

The Bourns Absolute Encoder is a digital control knob that provides 128 unique results evenly spaced around a full circle. It is designed as a control panel knob but can be adapted for other uses. This can be a good alternative to using a potentiometer and analog pin, as this allows for full-turn and multi-turn operation.

It differs from the more common incremental rotary encoder which has only two or four values in a rotation and is designed to measure full rotations and direction. This measures angles and absolute position is maintained between power cycles.

Includes:

• Nut and washer (9mm mounting hole)
• Solder jumpers
• Pull-down resistors for address pins

Features:

• 128 rotary positions
• Memory of last position before power-off
• 0.1" and Grove header locations
• ¼ in. round shaft (slotted end)
