## Description

A compact RS232-to-TTL level shifter board that converts both TX and RX lines bidirectionally. Powered from your target application's supply voltage, it automatically converts RS232 signals to match — run it at 5 V for 5 V TTL, or at 2.8 V for 2.8 V CMOS TTL levels. Includes TX and RX indicator LEDs. This version has no DB9 connector attached, making it suitable for field installations and projects where RS232 serial comes from non-DB9 sources. Key Features Bidirectional RS232 ↔ TTL – Converts both TX and RX lines Voltage Flexible – Operates at any supply voltage, converting RS232 to matching TTL levels TX/RX Indicator LEDs – Visual confirmation of data flow Wide Baud Rate Support – 300 bps to 115,200 bps No DB9 Connector – Bare board for custom wiring Specifications Conversion: RS232 ↔ TTL (TX and RX) Supply Voltage: Application-dependent (matches TTL output level) Baud Rate: 300–115,200 bps Dimensions: 1.2" × 1.1" (30.5 × 27.9 mm) Ideal For Microcontroller-to-computer serial communication Field installations with RS232 devices Legacy serial equipment integration Package Contents 1× RS232 Shifter SMD board (no DB9) Resources Schematic (PDF) Eagle Files (ZIP) GitHub Repository
