When I was studing power supply electronics in school, the instructor always talked about adding BFC’s to the circuit – Big Freakin’ Capacitors. This here is UHFC – Unbelievably Huge Freaking Capacitor. If you have a super-cap project that needs up to 630 Farads of capacitance, check it out. Like most super-caps it has a 2.5V-ma rated voltage, and remember that unlike a voltage-output battery the voltage drops immediately as it discharges.
You can use this as a stand-in for a battery, its huge but can charge fast and doesn’t degrade like NiMH or Li-Ion/LiPoly batteries. We like to refer to this MAXIM super-cap calculator to figure out how long we can run a project.
Super capacitors are powerful beasts: the ultra low ESR means that shorting the outputs will create a big spark! Care must be used when working with charged super-caps, these are only for experts who are comfortable with high-current-capable power supplies.
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.
