Uses the reliable FT232RL chip from FTDI for stable and high-performance USB to UART communication. This ensures a consistent and error-free connection across various devices.
Supports 3 different power modes: 5V, 3.3V output, or powered by the target board (3.3V-5V). This flexibility allows you to power your devices without worrying about compatibility.
Equipped with a protective plastic case to prevent static interference and short circuits, ensuring longevity and reliability even in demanding environments.
Works seamlessly with a wide range of operating systems, including Windows, Linux, and Mac OS, making it a versatile solution for diverse users.
Three LEDs (TXD, RXD, and PWM) help you easily monitor data transmission and power status, ensuring smooth operation and minimizing troubleshooting time.
We offer a 1-year warranty and lifetime technical support for this USB-to-TTL adapter。If you meet any question, Please contact us, We will fix your issue within 24 hours.
This product uses FTDI FT232RL chip by default, because of the chip out of stock, some production batches use FTDI FT232RNL model chip . Please do not worry, FT232RNL is also the chip produced by FTDI, can completely replace FT232RL. If you still care about these please contact us.
In the case of working with a MCU:
| Connection | Details |
|---|---|
| VCCIO ↔ 3.3V or 5V output | The module is powered from USB, and the onboard jumper should be shorted to 3.3V or 5V. |
| GND ↔ GND | Connect GND from the module to the GND of the MCU or PC. |
| TXD ↔ MCU.RX | Signal direction: MCU.RX << FT232 << PC.TX |
| RXD ↔ MCU.TX | Signal direction: MCU.TX >> FT232 >> PC.RX |
| RTS ↔ MCU.CTS | Signal direction: MCU.CTS << FT232 << PC.RTS |
| CTS ↔ MCU.RTS | Signal direction: MCU.RTS >> FT232 >> PC.CTS |
