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.

I’ve got a couple of those real-time crystals I obtained at some point in the past, and they’re in the same package as the one you picture above. Cylinder shaped. Any idea why that seems to be the most common package for that frequency of crystal, rather than the rounded box kind of shape used in most other through-hole crystals?
Inventorjack: The reason probably has something to do with the fact that these crystals are used in watches, where space — especially height — is really critical. The part design is quite versatile allowing for example to embed the crystal in a slot in the PCB. Newer 32.768 kHz crystals often have a square cross-section, they are probably better suited for automated soldering.
