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 programmin g Arduino Pro, ESP modules etc.. It also provides the pinout which follows the industry standard FTDI TT L 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 powe r 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 stan dard 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 sam e time . The two header rows are spaced 0.5″ apart along the sides of the board, which allow s the module to plug into a solderless breadboard . Each module is supplied with one right angle socket and two 7pin header s included. The user can select which ones to fit. Furthermore there are TX and RX LEDs to indicate data transmission on the UART signals.

1.1 Features

The LC231X module utilises the FT231X from FTDI. For a full list of the FT23 1X’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.  -40oC to +85oC operational temperature range  Full RoHS compliance

2 Typical Applications

 USB to UART bridge  Debugger / Programmer for embedded MCU e.g. Arduino  USB IO extender for small 8-bit micro’s

2.1 Driver Support

The LC231X requires USB drivers (listed below), available free from http://www.ftdichip.com, which are used to make the module appear as a virtual COM port (VCP). This allows the user to communicate with the USB interface via a standard PC serial e mulation port (for example TTY). Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the LC231X through a DLL. Both VCP and D2XX drivers support Windows auto-update. Royalty free VIRTUAL COM PORT (VCP) DRIVERS for...  Windows 10 32,64-bit  Windows 8/8.1 32,64-bit  Windows 7 32,64-bit  Windows CE 4.2, 5.0 and 6.0  Windows Server 2003, 2008 R2, 2012  Mac OS-X  Linux 2.4 and greater Royalty free D2XX Direct Drivers (USB Drivers + DLL S/W Interface)  Windows 10 32,64-bit  Windows 8/8.1 32,64-bit  Windows 7 32,64-bit  Windows CE 4.2, 5.0 and 6.0  Windows Server 2003, 2008 R2, 2012  MAC OS-X  Linux 2.4 and greater  Android(J2xx) For driver installation, please refer to the installation guides on our website: http://www.ftdichip.com/Support/Documents/InstallGuides.htm

Copyright © Future Technology Devices International Limited 6 LC231X Module Datasheet Version 1.1 Document Reference No.: FT_001388 Clearance No.: FTDI#516 The LC231X can support both 3.3V and 5V interfacing; the power jumper selection is through CN14. The default jumper setting is in 3.3V interface. Pin Number Description 1-2 3.3V IO interface (Default) 2-3 5V IO interface Table 3 - CN14 Jumper Selection If user require a simple UART interface (TX,RX,CTS and RTS),user can use CN11 which follow standard FTDI TTL interface. If user requires UART with full modem control and some extra configurable IO port, user can consider use CN12 and CN13 which provide UART with full modem control and IO port. The pin description of CN12 and CN13 is given by Table 4 and Table 5. Note the user could only fit either CN11 or CN12/CN13 connectors at the same time. Pin No Pin Name Type Description
