What is it?

This module is a fully hardware debounced rotary encoder

Why did you make it?

Rotary encoders are amazing in many applications but bouncing issues cause problems reading values and make them unsafe to connect to an interrupt pin of a micro-controller. Lots of CPU power is lost trying to poll and debounce using code. These bounces are filtered with a RC network filter and a Schmitt trigger gate, making it completely clean and easy to integrate in your projects without over-burdening your micro-controller with software tricks. This is even more relevant when dealing with low end 8 bit chips such as the atmega in the Arduino Uno where every CPU clock matters.

What makes it special?

This encoder was built with very high quality and reliability in mind. Its features include:

• High quality components: X7R capacitors from Samsung, 74LVC1G14 from Didoes Inc.
• Schmitt trigger action: safe to connect to an interrupt pin of a micro-controller.
• Low Voltage CMOS (LVC) logic family: Compatible with 1.8V, 3.3V and 5V logic levels at extremely high speeds.
• M2.5 mounting screw holes: Easily add the encoder to your projects and enclosures.
• RoHS compliant: Assembled with high quality SAC305 (Tin-Silver-Copper) lead-free solder.

Options

If you pick the Bourns rotary encoder module, the module will come with a Bourns PEC12R-4220F-S0024 high quality rotary encoder. This encoder features: - 24 Pulses - 24 Detents (the clicking sound at each step) - A switch - Standard 6mm diameter shaft - 20mm shaft length

Additionally, the module comes with a standard 5 pin right angle header that will make it easy to connect to a microcontroller.

Through hole components come Not soldered.
