The FT232RL USB to TTL Serial Adapter Module is a compact red board that connects a computer’s USB port to the UART serial pins of a microcontroller, supporting both 5V and 3.3V output voltage selection, with a Mini USB connector, RXD and TXD activity LEDs, a 500mA self-restore overcurrent protection fuse, and a DTR pin for automatic reset — making it the standard tool for programming Arduino Pro Mini boards and bare ATmega microcontroller chips that do not have built-in USB connectivity. This ft232rl usb to ttl converter module works exactly the same way as the FT232RL chip soldered onto a standard Arduino Uno — except here it is a separate module that gives any microcontroller access to USB programming from a PC.
The 5v serial adapter module for arduino’s switchable 5V and 3.3V output voltage means it can supply and communicate with both 5V Arduino-type boards and 3.3V boards like ESP8266-based modules without changing hardware. The usb to ttl ft232rl’s DTR pin is particularly important for Arduino programming — when the Arduino IDE initiates an upload, it briefly pulses the DTR pin to automatically reset the target microcontroller into bootloader mode, starting the upload without the user having to press any reset button manually.
The ft232rl serial adapter module’s RXD and TXD LEDs blink visibly whenever data is being transmitted or received, giving a quick visual confirmation that serial communication is active and data is flowing correctly. Available from StemVolt, offering electronics modules at competitive prices.
