If you want to make a kit you’ll need some solder. This 0.1 lb (about 50 grams) spool is a good amount, not too much (like 1 lb spools) and not too little (like those little ‘pocket clip’ vials).
This spool of solder contains approximately 0.6mm / .02″ diameter in standard 60/40 formulation. This is not lead-free solder, so not for lead-free/RoHS shops. However, for kit builders its a joy to use, much easier than lead-free and great for beginners. For flux, it contains a ‘no clean’ rosin core. This diameter solder is best for any SMT/fine-pitch work as it allows you to deposit small amounts of solder.
This is “60/40” leaded solder with 40% Pb (Lead), 59.5% Sn (Tin) and trace Ag (Silver) %0.015, Cu (Copper) %0.04. Sometimes this is referred to as [59.5/0.015/0.04]
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.
