FTDI to TTL serial module


SKU: GE000129 Category:


The FTDI to TTL serial module is a UART (universal asynchronous receiver-transmitter) board used for TTL serial communication. It is a breakout board for the FTDI FT232R chip with a USB interface and can be powered by either 3.3V or 5V DC. The module provides Tx/Rx and other breakout points for easy connection.

The FTDI to TTL serial module is commonly used for general serial applications and is popularly used for communication with microcontroller development boards that do not have USB interfaces, such as ESP-01s and Arduino micros .

Some key features and specifications of the FTDI to TTL serial module include:

  • Chipset: The module is built around the FTDI FT232R chip, which handles all the USB signaling and protocols.
  • Voltage: It can be used with either 3.3V or 5V devices, as it has adjustable TTL levels.
  • Power: The module draws power directly from the PC or laptop via the USB connection, eliminating the need for an external power adapter.
  • Connections: It provides access to UART Transmit (Tx), Receive (Rx), RTS#, CTS#, VCC, and GND connections.
  • LED Indicators: The module features RXD/TXD transceiver communication LED indicators, which provide a visual indication of the serial adapter status and data activity .
