Here is another super practical add-on for your Raspberry Pi computer, perfect for headless setups! The PiUART adds a micro USB to serial connection, allowing you to use any software with a serial port to connect to the Pi's console. The PiUART can be quickly and easily plugged in when you want to connect to your Pi. Two LEDs are connected to RX and TX on the serial converter chip, so they blink when data is sent or received.

Since we had some extra space, the PiUART also comes with a power switch featuring a 4-amp transistor. You can power your Pi through the micro USB port and then use the switch to turn off the power without having to unplug the cable. Low-power Pis like the Pi Zero and Pi A+ can be powered and controlled through a single cable connected to your computer. More powerful Pis like the Pi 2 and Pi 3 may draw too much power from a computer USB port, so check if your motherboard has a high-current USB port before trying it.

It comes fully assembled and ready to use; just connect your Pi and install the driver under Mac OS X - you'll be up and running in 2 minutes.

Works with any Raspberry Pi computer (Pi 1, 2, 3, Zero, etc.).
