## Description

The 2-Channel RS232 Module for Raspberry Pi Pico converts UART signals to RS232 and vice versa using the SP3232EEN transceiver. It plugs directly onto the Pico via the onboard female pin header — no wiring required. The module provides two independent RS232 channels with TVS and ESD diode protection. UART status LEDs indicate RX/TX activity on each channel, and a DB9 male connector can be used via an adapter cable. Demo code is available for both C/C++ and MicroPython. Key Features 2 RS232 Channels – Independent UART-to-RS232 conversion on each channel SP3232EEN Transceiver – Reliable RS232 level conversion Direct Pico Attachment – Female pin header for plug-and-play connection TVS & ESD Protection – Onboard diodes protect against surges and static discharge UART Status LEDs – RXD/TXD indicators for each channel DB9 Compatible – DB9 male connector available via adapter cable Demo Code Included – C/C++ and MicroPython examples for Raspberry Pi Pico Specifications RS232 Transceiver: SP3232EEN Communication Bus: UART Operating Voltage: 3.3V–5V Baud Rate: 300–912,600 bps Channels: 2 Ideal For Connecting Raspberry Pi Pico to RS232 industrial devices Serial communication with legacy equipment UART-to-RS232 bridging projects Data logging from RS232 sensors Package Contents 1× 2-Channel RS232 Module for Raspberry Pi Pico Note: Raspberry Pi Pico is not included.
