USB powered soldering iron, this scares us a bit – beyond possibly damaging your computer we can’t imagine it has good thermal properties (but if someone has another point of view, post up in the comments). The most you can get out of a USB port is 5V * 1amp (yes you can get 1 amp before the fuse blows) so thats 5W. We usually suggest 25 W irons to prevent cold solder joints and lifting pads.
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.
