Keyestudio FTDI(original chips) Basic Program Downloader USB to TTL FT232+USB cable for Arduino

This Keyestudio USB-to-TTL programmer uses an original FTDI FT232RL chip to establish a reliable serial connection between your computer and microcontrollers. It is an essential tool for students, makers, and engineers who need to program boards like the Arduino Pro Mini or debug serial communications.

Original FT232RL serial chip

The programmer features an original FTDI FT232 series chip, widely regarded as a highly reliable USB-to-serial solution. This ensures stable performance and debugging sessions without the risk of driver-related blue screens.

Selectable communication voltage

An onboard DIP switch allows you to toggle the serial communication voltage between 3.3V (also specified as 3.2V) and 5V. This provides the flexibility to safely interface with different logic-level devices.

Arduino Pro Mini compatibility

Featuring a standard interface, this module is compatible with various official Arduino controllers. It is ideal for uploading code directly to boards like the Arduino Pro Mini.

Onboard status indicator lights

The module is equipped with dedicated LEDs for power, sending, and receiving. These indicators allow you to easily check the real-time working and communication status of your connection.

STC microcontroller downloading

In addition to acting as a standard USB-to-serial TTL module, this downloader can be used to program STC microcontrollers. This makes it a versatile tool for diverse embedded electronics projects.
