Temperature Compensated Crystal Oscillators, or TCXOs, provide compensation at a higher temperature levels than can normally be achieved with standard crystal oscillators. These Raltron RTX0230LCs are fairly common at sites like eBay but their unique form factor makes them a little tricky for prototyping. Which is why Dan Watson at The Sync Channel designed these breakout boards that nominally scale up the footprint of the component to be compatible with more-standard 0.1″ breadboard spacing, with complete design files available on GitHub. They’re simple and they look great!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
