Keyestudio RJ11 EASY Plug Main Control Upgrade Board V2.0 Controller +USB Cable for Arduino STEAM

The Keyestudio RJ11 EASY Plug Main Control Upgrade Board V2.0 is an ATmega328P-based microcontroller designed to simplify electronics for students, educators, and makers. By replacing traditional jumper wires with secure RJ11 6P6C connectors, it eliminates the risk of incorrect wiring while teaching STEAM concepts. It is an ideal starting point for classroom robotics and rapid prototyping.

Error-free RJ11 connections

The board breaks out its IO ports into RJ11 6P6C plugs, consolidating VCC, GND, and signal lines into a single cable. This plug-and-play design prevents incorrect wiring and protects your external sensors and modules from electrical damage.

ATmega328P microcontroller core

Powered by the ATmega328P-AU microcontroller, the board operates at 5V with a 16 MHz clock speed. It includes 32KB of flash memory, 2KB of SRAM, and 1KB of EEPROM, making it fully compatible with the Arduino IDE.

Versatile digital and analogue IO

The board offers five single digital ports (D5 to D9) and a dual-digital interface (D3-D4). It also provides four analogue input pins (A0 to A3) for reading values from various sensors.

PWM outputs for motor control

Three of the digital ports (D5, D6, and D9) support PWM output, allowing for precise speed control of motors or positioning of servos. Each I/O pin supports a DC current of up to 20 mA.

Dedicated joystick and communication ports

A dedicated joystick interface (D2-A6-A7) simplifies the addition of analogue controllers to your builds. The board also features onboard interfaces for SPI, IIC, and serial port communication.

Dual power and programming options

Get started quickly by connecting the board to a computer with the included USB cable, or power it independently using the DC power jack. The recommended input voltage for the DC jack is 7-12V.
