Romeo BLE - Arduino Robot Control Board with Bluetooth 4.0
The Romeo BLE is an all-in-one Arduino-compatible robot control board from DFRobot with integrated Bluetooth 4.0. It combines an ATmega328P microcontroller, a dual-channel DC motor driver (2 A max), and a TI CC2540 BLE chip in a single board — letting you build and wirelessly control robots witho...
Bluno Mega 2560 - An Arduino Mega 2560 with Bluetooth 4.0
The Bluno Mega 2560 combines the ATmega2560 microcontroller with an integrated TI CC2540 Bluetooth 4.0 (BLE) module, bringing wireless communication to the Arduino Mega form factor. It supports wireless programming over BLE, Bluetooth HID, iBeacon, and serial pass-through — while remaining fully ...
Arduino DTMF Shield
The Arduino DTMF Shield is a dual-tone multi-frequency decoder module that lets your Arduino interpret touch-tone signals from phones. Connect it to a GSM/GPRS shield and you can send commands to your Arduino via phone call — press buttons on your phone to control motors, lights, or any connected...
Plastic mounting plate for breadboard and Arduino - rubber feet!
By popular demand! We now have the plates from the ARDX available separately. Acrylic plate is engraved and cut here at the Adafruit factory. There are mounting holes for your Arduino and a space that fits a half sized breadboard very nicely. THIS DOES NOT FIT THE ARDUINO MEGA. Comes with: ...
LilyPad Arduino 328 Main Board
The LilyPad Arduino 328 Main Board is an Arduino-programmed microcontroller designed to be easily integrated into e-textiles and wearable projects. It offers the same functionality you find in other Arduino boards, in a lightweight, round package designed to minimize snagging and profile, with wi...
Gravity: Arduino PIR (Motion) Sensor
A passive infrared (PIR) motion sensor from DFRobot's Gravity series. It detects infrared radiation from people and animals in motion and outputs a digital HIGH signal when movement is detected — ideal for security systems, occupancy sensing, and automated lighting projects. The sensor operates ...
