Keep your microcontroller tickin' with a ceramic oscillator. These little devices are bread-board friendly (0.1" pin spacing) and easy to use. They act much like crystals with the 'stability' capacitors inside. They have 0.5% accuracy, great for everyday electronics and microcontroller work, and are certainly precise enough for UART or other baud-rate generation. For ultra-high precision needs (USB timing, long-term time-keeping, RF/PLL/VCO driving) you may need a crystal or temperate-compensated oscillator.

This is a good match for people building Arduino-compatibles since the Arduino Uno is clocked at 16MHz

To use, connect the two outer pins to XTAL-in and XTAL-out on your circuit (the package is symmetric so use whichever outer pin) and the inner pin to ground. Check the datasheet for more specs.

Note: The ceramic oscillator may come in brown or blue. Both have the same functionality. We cannot guarantee which one you will receive.
