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]
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
