New HW and FW version! Connect rotary encoders on the I2C busDesigned by DUPPA in Italy
Due to the COVID-19 the delivery time is increased a lot, specially outside Europe.
Please refer t your local poste company and if you are in hurry use DHL!
This project has been successfully founded on KickStarter! Check out also the MickMake and EEVblog videos! What is it? The I2C Encoder is a tiny board that you can read a mechanical rotary encoder ...Read More…
The I2C Encoder is a tiny board that you can read a mechanical rotary encoder on the I2C bus. The I2C Encoder V2 supports various type of rotary encoder with one footprint:
There are also 3 configurable GPIOs that are organized with the same footprint of RGB LED. You can use them as PWM, I/O or ADC. Last but not least, it has also 256bytes of EEPROM.
There is also the little brother I2C Encoder Mini
This new version is powered by the PIC16F18345. Respect to the MCU on the first version, it has more GPIO and the EEPROM memory. The new design of the board support both the standard encoders and the illuminated RGB encoders. Moreover, there are the castellated holes on all the 4 sides of the board, in this way will be possible to connect multiple boards by soldering them like a matrix.
The I2C Encoder V2.1 have also pre-soldered the pull-up resistor on the I2C bus. The can be enabled by soldering a jumper.
The I2C Encoder V2.1 can be used in two different scenarios:
There are 4 registers:
These 4 registers can be 32bit signed INT, or as float numbers IEEE 754.
The I2C Encoder has also the possibility to control LEDs. The LEDs are controlled by an 10bit PWM.
There is also the possibility to enable a gamma correction for the LED color.
There are also 3 configurable GPIOs organized with the same footprint of an RGB LED. They are called GP1, GP2, and GP3. But in case you are using the RGB encoder, the configurable GPIOs are only 2: GP1 and GP2.
1 I2C Encoder V2.1 board fully programmed (without encoder, connector and LED)
However, there are some accessory taht you can add into your order according to your preference. The accerssory are not soldered, you have solder by your self.
There are 4 types of standard encoders. All have 20 pulses for rotations and the push button:
There are also an illuminated RGB Encoder with the following characteristics:
There are 2 type of knobs only for the RGB Encoder, not for the others encoder:
Complete transparent knob:
Black knob with illuminated ring:
There are also 2 type of connector:
Example of mounting with JST connector with 30cm wire:
Example of male and female 5 pin header
This is a 40mm LED ring with 48 RGB LED working on the I2C bus. It perfectly fit on the RGB Encoder and the normal encoder.

This is an upgraded version of our previous project I2C Encoder V2
