The RedStick is a USB board with an ATmega328P at its core

The SparkFun RedStick is a production version of the BadgerStick, a board you’ve probably seen at a recent tradeshow inside the BadgerHack Badge. 

Last year, the SparkFun crew developed the BadgerStick as a fun and interactive way for Makers to learn about soldering and engaging with various boards at trade tradeshows. Now, the team has refined the BadgerStick into something they’re calling the SparkFun RedStick!


At the heart of the new device is an ATmega328P running at 16MHz. Makers will take comfort in knowing that the RedStick is packed with many cool features, including the Arduino Uno’s Optiboot bootloader, its compact form factor, FTDI and the ability to be plugged directly into a computer’s USB port (no FTDI board or USB cable required).

What’s more, the board can be programmed using the Arduino IDE. Simply insert the board, select “Arduino Uno” from the menu and you’re ready to upload code. The RedStick boasts 14 digital I/O pins with six PWM pins, eight analog inputs, UART, SPI, I2C and external interrupts.


The SparkFun RedStick can be juiced up over USB or through its power input (which supports a JST connector). Additionally, an onboard boost regulator provides 5V to the ‘328P from an input range of 2 to 6V. While the RedStick does not included a battery charger, it can be powered over a single-cell LiPo or even a pair of AA batteries.
