mLab REM328 Rotary Encoder Module
The REM328 is a universal rotary encoder module featuring an ATMEGA 328/16MHz microcontroller with Arduino bootloader.
You can upload your own sketches via FTDI or ISP.
All components are surface-mounted on the solder side, with perfectly aligned through-hole pads for encoders, displays, and Neopixel devices.
Module Features
- Interfaces: ISP, SPI, FTDI, SERIAL I/O, GPIO pads
- Supports EN11 or EN12 rotary encoders with push switch
- OLED and RGB TFT displays (I2C/SPI) support
- Neopixel LED integration
Pads Overview
- 5 pads for rotary encoder with push switch
- 8 pads for OLED or RGB TFT displays
- 9 GPIO pads
- 6 ISP/SPI pads
- 5 FTDI pads
- 3 pads for general-purpose Neopixel devices
- 4 pins for piggyback Neopixel LED Ring PCB

Neopixel LED Ring
The optional Neopixel LED Ring PCB mounts directly on the encoder, but you can use any Neopixel chain by wiring the DO output to the next DI input.
