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]
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
