SparkFun Arduino Pro 328 3.3V/8Mhz

The SparkFun Arduino Pro 328 3.3V/8MHz is a compact electronics module designed for advanced users familiar with the specific requirements and limitations of a 3.3V system. This module features a minimalist design and is ideal for projects that require a lower operating voltage. It comes equipped with an 8MHz bootloader and allows the use of 3.3V sensors, making it an excellent choice for applications that need lower voltage. The board does not come with pre-installed connectors, giving users the flexibility to design the necessary connections themselves. The use of SMD components and a double-layer PCB contributes to the cost-effectiveness and low profile of the module. The Arduino Pro is not compatible with many 5V Arduino shields but offers the opportunity to create custom 3.3V shields, especially when combined with SparkFun's Prototyping Shield.
