## Description

The Adafruit RS-232 Full Pinout Level-Shifter Breakout lets you interface any 3.3 V microcontroller or single-board computer with RS-232 devices using all 8 data/flow-control signals. Built around the trusted TI MAX3243, it generates the required positive and negative voltages internally and provides 5 input and 3 output channels of level shifting at up to 250 Kbps. RS-232 uses ±6 to ±10 V signal levels — far outside the range of standard 3.3 V or 5 V logic. This breakout handles all the voltage generation and conversion, and comes fully assembled with a DE-9F connector ready to plug directly into your RS-232 device. Key Features MAX3243 Level Shifter – 8 channels (5 input, 3 output) for full RS-232 pinout including RTS, CTS, DTR, DSR, DCD, and RI 3.3 V Power & Logic – Runs on 3.3 V, compatible with modern microcontrollers (many older RS-232 chips require 5 V) Up to 250 Kbps – Suitable for most RS-232 communication needs DE-9F Connector – Standard 9-pin D-Sub connector for direct plug-in to RS-232 devices Valid Signal Output – Logic-level output goes high when RS-232 signal voltages are detected (connection indicator) Off/Tri-State Pin – Set high to tri-state all pins for power reduction Fully Assembled – UART side for low-voltage logic, DE-9F side for RS-232; header included for breadboard use Ideal For Interfacing with industrial and telco equipment Retro computing and legacy device communication Barcode scanners, modems, and serial terminals Any project requiring full RS-232 flow control signals Package Contents 1× Adafruit RS-232 Full Pinout Level-Shifter Breakout (fully assembled with DE-9F connector) 1× Header strip (soldering required for breadboard use)
