Digispark - ATtiny85 with USB male

A very small Arduino with USB that is very suitable for smaller applications!
The nice thing is that the ATtiny85 can be programmed without needing another Arduino or a programmer. This is because USB software runs in the ATtiny85 itself.
This standard variant has a piece of PCB as a USB connector.
A few pin headers are included that you can solder on the board.
Note: Some laptop/computers have a too deep USB port. As a result, you may have to use a USB extension cable.
