Description

The FTDI FT232RL USB-to-TTL Programmer is a reliable and widely used USB-to-serial converter built around the FT232RL chipset.
It allows seamless communication between a computer’s USB port and microcontrollers, development boards, and embedded systems.
The module supports both 3.3V and 5V output levels, selectable via an onboard jumper, making it compatible with a wide range of devices.

It is commonly used for programming ESP8266 (ESP-01), flashing firmware, debugging UART communication, and interfacing with routers, GPS modules, GSM modules, and other serial devices.
Featuring stable drivers and high-speed USB communication, it is preferred in professional and hobbyist electronics environments.
