Blend BLE Microcontroller
RedBearLab Blend V1.0 Arduino ATmega32u4 BLE
Blend is RedBearLab's integrated development board. With the Blend BLE Microcontroller they have "blend"ed Arduino with Bluetooth 4.0 Low Energy (aka BLE or Bluetooth Smart) into a single board. It is targeted for makers to develop low power Internet-Of-Things (IoT) projects quickly and easily.
Blend is 100% compatible with sketches and Shields that work with Arduino Leonardo. The micro-controller unit (MCU) is Atmel ATmega32U4 and the BLE chip is Nordic nRF8001.
- Utilize Nordic Bluetooth Smart SDK for Arduino
- Software development using Arduino IDE or codebender
- Works with our free Android App and iOS App
- Support 5V and 3.3V operating voltage
- Selectable REQN and RDYN pins, from pin 0 to 3, 6 to 11
- Flexible RF RESET pin, pin 4 or 5
- Over-the-Air download of sketch to Blend (available soon)
- Besides the on-board PCB antenna, option to use SMA connector for external antenna (soldering is required)
