What does the USB to TTL cable add to my Raspberry Pi?
This cable provides you with an easy way to interact directly with your Raspberry Pi from the USB of your computer. The wires are separated at the other end of the cable, making it easier make connections.

The USB to TTL cable transfers both power and data, two ingredients vital for building projects. The cable is 36-inches long, offering your project both flexibility and enough range to cover a small distance if needed.

What can I use this cable for with Arduino?
This cable is capable of monitoring the output of an Arduino's UART or for boards without a USB port can be used to upload a sketch.

How can I connect using this USB to TTL cable?
The data is passed from the USB plug and is broken out into a signal in four individual wires. There are four coloured wires (red, black, white and green) coming from the USB plug and leading to four female jumper wire sockets.

The wires have different purposes:
The red wire provides 5V at 500mA for power
The black wire makes a ground connection
The white wire connects to a receiving RX data pin
The green wire connects to a transferring TX data pin

You can use this knowledge to access, modify and hack existing and old equipment. This can include devices such as Wi-Fi routers and similar systems that operate with a 3.3V logic serial port.

What is the USB to TTL cable compatible with?
This product is good for connecting to microcontrollers and the Raspberry Pi.

Please see the Downloads Tab for how to use this device if you have a Windows or MacOS computer.
