Good evening, this is Bono.
When you are working with Raspberry Pi, you inevitably have many opportunities for jumper wires. Because the Raspberry Pi has protruding pins, a female jumper is necessary.
However, in general, most jumpers that come as electronic construction kits are of the double-sided male type.
Here is a reference for you when buying a new female jumper.
Buying on Amazon is expensive!
If you're thinking, "I'll just go to Amazon for these things," you might want to wait a bit.
There are not many cheap jumpers available on Amazon.
At the cheapest, 10 pieces of 15cm x 10 pieces cost more than 400 yen.
Shop for raspberry pi jumpers at Yahoo!
The recommendation is definitely Yahoo! Shopping.
What a surprise, there are 20cm x 10 pieces starting at 150 yen.
And since I can use T points, this time it was free even if I put 160 yen for shipping! (I'm not a turner, lol)
