This 9V battery clip with DC plug also works great for premade electronics. It allows to easily add 9V DC supply to your circuit and can be used for projects where circuit boards are to be placed away from your bench top power supply.

The cable is battery power suit for any device that needs 9V and has an on-board barrel jack,works great for development boards, evaluation boards.

No need to rely on plug power to power your non-battery guitar effects, so easy to perform around the world.

The internal switches are bidirectional, support voltages between ground and VCC, have low “on” resistance and low “off” leakage, and to prevent crosstalk, perform “break-before-make” switching. The board also breaks out the chip’s “enable” pin, which when driven high, will completely disconnect the common pin (all switches “off”).

To control it, connect 4 digital outputs to the chip’s address select pins (S0-S3), and send it the binary address of the channel you want. This allows you to connect up to 16 sensors to your system using only 5 pins.

Since the mux/demux also works with digital signals, you can use it to pipe TTL level serial data to or from multiple devices. For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller. You can then select any one of those 16 devices to listen to.

The battery holder is fixed by a stainless steel spring. It is very convenient to install and replace the battery, and it is not easy to damage other parts.
