“This isn't the first time I've purchased these connector assemblies from The Pi Hut and it probably won't be the last time either. These jumper assemblies are perfect for the BBC micro:bit, Wemos D1 minis and many other boards.
Good quality crimping tools suitable for these connectors can be prohibitively expensive for the hobbyist which can prevent them from using these connectors. The Pi Hut solves this problem by providing these pre assembled cables at an affordable price.”
