RFD51822

Bluetooth Low Energy Module

BLE + ARM + Antenna

Shrunk down an Arduino to the size of a finger-tip and made it wireless.

RFD51822

The RF Digital RFD51822 module is a READY-TO-USE Bluetooth 4.0 Low Energy wireless solution based on the Nordic nRF51822 Multi-protocol Bluetooth Low Energy and 2.4GHz proprietary system-on-chip. Footprint and pin compatible with the RFD21733 line of RF Modules. Built-in DC/DC converter circuit for additional power savings.

The RF Digital RFD51822 module is the "brains" of the new RFduino - a finger-tip sized, Arduino compatible, wireless enabled microcontroller, currrently featured on Kickstarter.

Features:

  • 2.4GHz multi-protocol device
  • 32-bit ARM Cortex M0 CPU core
  • 256KB flash 16KB RAM
  • Thread safe and run-time protected
  • Event driven API
  • 3 data rates (2Mbps/1Mbps/250kbps)
  • +4dBm output power
  • -92.5dBm sensitivity, Bluetooth low energy
  • PPI system for maximum power-efficient applications and code simplification
  • Flexible power management system with automatic power management of each peripheral
  • Configurable I/O mapping for analog and digital I/O

 

 

RFduino: A finger-tip sized, Arduino compatible, wireless enabled microcontroller, low cost enough to leave in all of your projects.

RFduino uses the new RF Digital RFD51822 Bluetooth 4.0 Low Energy compliance approved module which is based on the Nordic nF51822 award winning SoC.

The RFduino runs Arduino code and can do everything an Arduino can, plus much more.

Using the RFduino USB shield, simply plug the RFduino into a USB port of any computer and use the Arduino IDE to load your Arduino sketch, which automatically begins running on the RFduino.

Then you can detach the RFduino USB shield and plug the RFduino directly into your poject.
