USB to TTL Serial UART RS232 Adaptor (PL2303TA)

USB to TTL converters are essential for prototyping - they provide a direct interface with the target device. This module connects to your computer USB port and there are 4 wires which connect with your target device. NOTE: This product may come in a black or blue variant and are functionally identical. Please also note that RS232 conversion, in this case, doesn't have the true voltage doubler/inverter and as such isn't compatible with some RS232 standardized devices if you're looking for a converter that does please look here

Features:

• Fully enclosed professional finish.
• Built-in PL2303TA USB to Serial Controller
• Designed to be used for USB to TTL electronic projects
• TTL interface output, easy to connect to your MCU
• Dual 3.3V and 5V Power output (by Changing the red wire termination)
• Can independantly power the circuit with 5V or 3.3V
• Compact design

Operation:

• Red - power. This pin provides up to 500mA current. YOU MUST NOT use other power supplies if you choose to power the target device with this Adaptor.
• Black - ground (always needed, regardless if the Adaptor is powering the target device or not)
• White RX (3.3V, which is compatible with 5V logic)
• Green TX (3.3V, which is compatible with 5V logic)

3.3V and 5V Selection:

Open the plastic case (twist the USB connector and then evenly pull apart the plastic case) and change the red wire termination from the pad marked 5V or 3V3.
