Arduino Pro 328 - 3.3V/8MHz Category_Radio & Wireless/Wi-Fi GPIO Header Pinout

GPIO Header Pinout

32-bit ARM Cortex-M0+ microcontroller also featured on the Arduino Zero and SAMD21 Mini Breakout boards

need to program the Teensy for any Arduino shield you’d like to work with

the PCB comes with four 2

which would indicate a maximum motor supply of 5 V

Arduino Pro 328 - 3.3V/8MHz Category_Radio & Wireless/Wi-Fi GPIO Header PinoutIt\'s blue! It\'s skinny! It\'s the Arduino Pro! SparkFun\'s minimal design approach to Arduino. This is a 3. 3V Arduino running the 8MHz bootloader. Because the system voltage for this board is lower than other Arduino development boards, it may not be compatible with many Arduino shields which were designed to run at 5V. The Arduino Pro 3. 3V still works great with our prototyping shield so you can create your own 3. 3V shields. The lower system
