1 Introduction

The LC231X module is a low cost USB to UART

bridge using FTDI’s FT231X to transfer data at up

to 3M Baud. Ideal for programming Arduino Pro,

ESP modules etc.. It also provides the pinout which

follows the industry standard FTDI TTL cable

interface. The module provides the UART interface

with full modem handshaking control too.

The LC231X IO interface also provides the option

to output 5V power to external hardware. The

interface IO levels may be set to either set to 3V3

or 5V by an on-board jumper with no soldering /

de-soldering required. In 5V mode, outputs are rail

to rail for maximum reliability.

The LC231X module provides 2 interface options.

One is a 1X6 pin right angle socket header which

follows the industry standard FTDI TTL cable

interface for basic UART signals(RXD, TXD, RTS,

CTS, Power and GND). The other is the full UART

plus modem handshake control signals, mapped to

two rows of 1x7 pin headers. Note the user cannot

fit all connectors at the same time.

The two

header rows are spaced 0.5″ apart along the sides

of the board, which allows the module to plug into

a solderless breadboard. Each module is supplied

with one right angle socket and two 7pin headers

included. The user can select which ones to fit.

Furthermore there are TX and RX LEDs to indicate

data transmission on the UART signals.

Features

The LC231X module utilises the FT231X from

FTDI. For a full list of the FT231X’s features

refer to the FT231X datasheet.

In addition, the LC231X

has the following

features:



Small PCB size as 15.24mm X 28.19mm



Configurable IO voltage interface



USB 2.0 full speed



Provides a full modem control interface



Low supply current :10mA



Supported baud rates: 300 bps to 3 Mbps



Power output to external logic 5V/3V3



Provides two I/O header options:

-

One 1X6 pin right angle socket header

for standard FTDI TTL cable interface,

-

Or two rows of 1x7 pin headers for full

modem handshake control and GPIO

functions.
