Product Description

This Rotary encoder with Stemma QT makes all that frustration go away - solder in any 'standard' PEC11-pinout rotary encoder with or without a push-switch. The onboard microcontroller is programmed with our seesaw firmware and will track all pulses and pins for you and then save the incremental value for querying at any time over I2C. Plug it in with a Stemma QT cable for instant rotary goodness, with any kind of microcontroller from an Arduino UNO up to a Raspberry Pi.

You can use our Arduino library to control and read data with any compatible microcontroller. We also have CircuitPython/Python code for use with computers or single-board Linux boards.

It's also easy to add this breakout to a breadboard - with six 0.1"-spaced breakout pads. Power with 3 to 5V DC and then use 3 or 5V logic I2C data. The INT pin can be configured to pulse low whenever rotation or push-buttoning is detected so you do not have to spam-read the I2C port to detect motion.

There's a NeoPixel onboard, that can display any color you like. It's also controlled over I2C for additional visual feedback or keep it off if you like. On the back there's a green power LED as well as a red INT LED that, if the interrupt is configured, will blink when the interrupt fires.

Using the three onboard address jumpers, you can connect up to 8 of these rotary encoders on a single I2C port. The first one will be at address 0x36, the last one at 0x3D when all three jumpers are soldered closed.

This breakout does not come with an encoder soldered on.
Default I2C address is 0x36
Product Dimensions: 25.6mm x 25.3mm x 4.6mm
Product Weight: 2.4g

Revision History:

As of June 15, 2022 - This board may come with a different regulator than AP2112K due to parts shortages. The regulator can provide at least 250mA.

Wenn man mal etwas mehr Drehregler benötigt

Ich habe diese Boards in einem Projekt im Einsatz, bei dem ich mehrere Drehregler gleichzeitig verwenden muss. Ein normales Mikrocontroller-Board wie ein Arduino oder auch ein Raspberry hat meist nicht genug Pins, um ohne weiteres mehrere Drehregler und deren Interrupts anzuschließen. Hier hilft dieses Board, indem es den Drehregler über i2c abrufbar macht. Unterstützung für das Seesaw Protokoll, das dabei verwendet wird, gibt es von Adafruit selbst für Arduino und für Python. Andere Systeme werden meist durch Drittbibliotheken auch noch unterstützt. Ich selbst nutze das Board auf einem Raspberry in einem .NET 6 Projekt.
