Description

• Key Features:

  ✔ FTDI FT232RL Chip – Industry-standard USB-UART bridge with driver support for Windows/Linux/macOS.
  ✔ 6-Pin Interface – Includes TX, RX, GND, VCC (5V), CTS, RTS for full hardware flow control.
  ✔ 5V/3.3V Logic – Jumper-selectable voltage (protects 3.3V devices like ESP8266).
  ✔ Plug-and-Play – No external power needed (draws power from USB).
  ✔ High-Speed Transfer – Up to 3Mbps baud rate (adjustable).
  ✔ 6-Pin Terminal Line – Pre-soldered Dupont cables for easy MCU connection.
  ✔ LED Indicators – TX/RX activity lights for debugging.

  Applications:

  • Firmware Flashing – Program ATmega, ESP, STM32, Raspberry Pi Pico.

  • Serial Debugging – Monitor logs from microcontrollers.

  • GPS/GSM Modules – Connect to UART devices with flow control.

  • Industrial Control – Interface with PLCs, sensors, and legacy systems.

  Pinout (6-Pin Terminal):

  1. GND – Ground

  2. CTS – Clear to Send (flow control)

  3. VCC – 5V/3.3V output (jumper-selectable)

  4. TXD – Transmit data (to MCU’s RX)

  5. RXD – Receive data (from MCU’s TX)

  6. RTS – Request to Send (flow control)

  How to Use:

  1. Connect to PC – Plug into USB (auto-installs FTDI drivers).

  2. Set Voltage – Jumper to 3.3V or 5V (match target device).

  3. Wire to MCU – Link TXD→RX, RXD→TX, GND→GND (CTS/RTS optional).

  4. Open Serial Terminal – Use Arduino IDE, PuTTY, or CoolTerm.

  Why Choose This Adapter?

  ✅ Stable & Trusted – FTDI chip avoids counterfeit driver issues.
  ✅ Flow Control Support – Prevents data loss in high-speed transfers.
  ✅ Compact & Durable – Shielded cable reduces interference.

  Note: Some boards require DTR/RTS for auto-reset (e.g., Arduino). Check pin compatibility.
