Description

EC11 Rotary Encoder DIY Breakout PCB (Empty Board for DIY Soldering)

A simple and compact DIY-friendly PCB designed for the popular EC11 rotary encoder. This breakout board allows hobbyists, students, and makers to easily mount and solder their own EC11 encoder for use in Arduino, ESP32, STM32, and other microcontroller projects.

The board brings out all the EC11 pins to clearly labeled solder pads or header pins, making prototyping and integration straightforward.

Features

• Compatible with EC11 rotary encoder (standard 5-pin mechanical type with optional switch).

• DIY soldering kit style: Sold as an empty PCB only – users solder their own EC11 encoder and headers.

• Compact layout: Small size, perfect for breadboard or embedded projects.

• Clearly labeled pins: Easy identification of CLK, DT, SW, VCC, and GND.

• Optional switch support: Supports the built-in push button of EC11 encoders.

• Robust PCB quality: FR4 material, solder mask, silkscreen, plated through-holes.

• Multiple mounting options: Can be used with straight or angled headers depending on your project needs.

Typical Applications

• Arduino / ESP32 / STM32 projects with rotary input

• Volume control knob for audio projects

• Menu navigation for LCD/OLED screens

• Robot and CNC control interfaces

• General DIY electronics and maker projects

PCB Specifications

• Material: FR4, 1.6 mm thickness

• Copper: 1 oz (35 µm)

• Solder mask: Green (other colors optional on bulk orders)

• Dimensions: Compact design (typically ~25×20 mm, can adjust to your board size)

• Hole plating: Yes (through-hole)

• Pads: Sized for easy manual soldering

What’s Included

• 1× EC11 Encoder DIY PCB (empty)

• Note: Encoder, headers, and other components are not included – this is intended as a DIY soldering board.

👉 This makes a great training tool for students learning soldering skills, as well as a neat accessory for makers who want to quickly integrate rotary encoders into their projects. Use this Diagram for SMD Assembly and Soldering guide
