SparkFun RedStick [DEV-13741] - (AD29356)

Description:

In 2015, we developed the BadgerStick as a fun and interactive way to learn about soldering and interact with SparkFun products at the multiple trade shows we participate in. In 2016, we refined it into what you see here: the SparkFun RedStick! The RedStick combines some of our favorite features such as the Uno’s Optiboot bootloader, FTDI technology, a small footprint, and the ability to plug directly into a computer’s USB port (no FTDI breakout or USB cable required).

The RedStick can be programmed by simply plugging the board into your computer using the Arduino IDE — just plug the board in, select “Arduino UNO” from the board menu, and you’re ready to upload code. The RedStick also features the usual hardware characteristics: 14 digital I/O pins with 6 PWM pins, 8 analog inputs, UART, SPI, I²C, and external interrupts. All of this comes in a small package that plugs directly into your computer.

You can power the SparkFun RedStick either by the USB connector or through the power input (which supports a JST connector for a single-cell LiPo battery). The onboard boost circuit can regulate any voltage from 2–6V. Even though the board does not include a battery charger, it can be powered by a single-cell LiPo battery or even 2 AA batteries. Check out our related products for battery and battery housing information.

Features:

• A boost regulator that provides 5V to the Atmega328p from an input range of 2–6 volts.
• 16MHz system clock (allowed thanks to the additional supply voltage).
• Uno compatible in the Arduino IDE. Simply select the “Arduino/Genuino Uno” board and go!
• USB end matches standard USB thickness and width.
