FT232RL FT232 USB to TTL Download Cable to Serial

The FT232RL FT232 USB to TTL adapter turns a computer USB port into a TTL-level serial port using the FTDI FT232RL chip. It lets you upload sketches to boards without their own USB port, such as the Arduino Pro Mini, flash ESP8266 and ESP32 modules, and read serial debug output from microcontrollers, GPS modules and other UART devices.

FT232RL FT232 USB to TTL Applications

• Uploading sketches to the Arduino Pro Mini and other boards without USB
• Flashing firmware on ESP8266 and ESP32 modules
• Serial debugging and logging from microcontrollers
• Talking to GPS, Bluetooth and other UART modules from a PC terminal
• Configuring HC-05 Bluetooth modules with AT commands

What's in the Box

• 1 × FT232RL USB to TTL serial adapter

Tip: Cross the data lines: connect the adapter's TXD to the target's RX and RXD to TX, and join the grounds. Check the adapter's logic level before connecting it to 3.3 V devices such as the ESP8266 or ESP32, because 5 V signals can damage them.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
