== Summary ==
The FT232 USB UART Board (micro) is a Waveshare module that converts a USB interface to TTL levels. It uses an FTDI FT232 chip and enables serial communication between a PC and TTL devices such as microcontrollers or sensors via a micro-USB connector.

== Technical overview ==
* Type: USB-to-UART-TTL module with a micro-USB connector
* Power supply: 5 V; TTL level switchable between 3.3 V and 5 V via jumper cap
* Maximum baud rate: up to 3 Mbit/s (FT232RNL)
* Supported operating systems: Windows 7/8/8.1/10/11, macOS, Linux, Android
* Pinout (upper row): VCCIO, GND, TXD, RXD
* Pinout (lower row): 5V, GND, CTS#, RTS#
* Additional signal lines: RI#, DCD#, DTR#, DSR#, RESET#, CBUS0–CBUS4
* Operating range: temperature -15 °C to 70 °C, humidity 5 % RH to 95 % RH
* Wiring logic: the module's TXD connects to the MCU's RX, and the module's RXD connects to the MCU's TX

== Notes and version constraints ==
* The exact driver files for Windows, macOS, and Android must be obtained from the official FTDI site; the source references external links that cannot be reproduced here.
* Steps for pinning a fixed COM port are version-dependent (Windows 10/11); the exact UI may vary by system version.
* When powering external devices at 3.3 V, insufficient supply current can cause blinking TXD/RXD indicators; resolution requires opening the FTDI programming tool to enable a strengthened 3.3 V supply current – this step requires human confirmation.
* Overvoltage, overcurrent, electrostatic discharge, extreme temperatures, or electromagnetic interference can damage the FT232 chip; appropriate protective measures are required.
* The source notes the presence of knock-offs on the market; authenticity should be verified when purchasing from non-official stores.
