A clock for the Raspberry Pi

gp

The Raspberry Pi is a handy tool, but it has some quirks. One quirk is that there is no internal clock with a battery backup (something most real PCs have). Instead, it syncs with online clocks via TCP/IP.

If you don’t want to rely on that mechanism, you could you use this, but then it takes up some of your GPIO pins. Instead, you can use this new product.
