If you want to make a kit you'll need some solder. This 0.1lb / 50g 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 0.5mm / .02" diameter in standard SAC305 formulation. This is lead-free solder, so great for lead-free/RoHS shops.For flux, it contains a 'no clean' rosin core. It's good for all through-hole soldering and great for any kind of SMT soldering. Contains Sn 96.5%, Ag %3.0, Cu %0.5 (96.5/3/0.5) sometimes referred to as SAC305. Perfect for when you need a lead-free alternative to classic 60/40! https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-11-01 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-11-08 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-11-10 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-11-25 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-11-28 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-12-03 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-12-14 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2025-12-19 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-01-10 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-01-23 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-01-26 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-01-31 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-02-03 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-02-11 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-02-19 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-03-03 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-03-08 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-03-15 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-03-17 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-03-24 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-03-27 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-04-08 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-04-15 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-04-27 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-05-07 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-05-15 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-05-19 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-05-31 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-06-04 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-06-07 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-06-15 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-06-19 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-06-27 https://elecena.pl/product/29469192/adafruit-solder-wire-sac305-rohs-lead-free-0-5mm-02-diameter 2026-07-01
