## Description

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](https://core-electronics.com.au/usb-serial-converter-ft232rl.html)*

### 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)
