## Summary description

Waveshare SP3232EEN is a 2-channel RS232 transceiver module designed for use with Raspberry Pi Pico to convert between UART and RS232 signal levels. The board provides two independent UART-to-RS232 channels for connecting legacy serial devices, industrial controllers, modems or instrumentation. It supports standard RS232 signaling for reliable serial communication and simplifies integration of Pico-based projects with RS232 equipment.

## Long description

The Waveshare SP3232EEN is a 2-channel RS232 transceiver module designed to interface Raspberry Pi Pico UARTs with standard RS232 equipment. The board converts between TTL-level UART signals used by the Pico and true RS232 voltage levels, providing two independent serial channels for connecting legacy serial devices such as industrial controllers, modems, instrumentation, or other RS232 peripherals. The compact module simplifies adding RS232 connectivity to Pico-based projects and supports reliable, bidirectional serial communication between microcontroller UARTs and RS232 endpoints.
Advantages
The module offers two isolated UART-to-RS232 channels on a single compact board, reducing the need for additional level-shifting circuitry. It implements standard RS232 signaling for compatibility with a wide range of legacy devices and industrial equipment. The design is suitable for direct connection to Raspberry Pi Pico UART pins and minimizes wiring complexity. The SP3232EEN supports full-duplex communication and helps maintain signal integrity across typical RS232 cable lengths.
Suitable for
Connecting Raspberry Pi Pico projects to RS232 modems and serial terminals
Interfacing Pico with industrial controllers and PLCs that use RS232
Data logging and instrumentation that require legacy serial communication
Prototyping embedded systems with dual independent serial ports
Key specifications
Number of channels: 2 independent UART-to-RS232 channels
Interface type: RS232 signal level conversion for UART
Supported communication: full-duplex serial on each channel
Compatibility: designed for use with Raspberry Pi Pico TTL UART pins
Form factor: compact PCB suitable for integration into small projects
Typical use: connection to legacy serial devices, modems, instrumentation
How to use
Connect the module's UART input pins to the Raspberry Pi Pico UART TX/RX pins and provide the recommended VCC and GND connections as specified by the Pico. Attach the RS232 devices to the module's RS232 connectors or header lines, ensuring correct TX/RX orientation. Configure the Pico firmware serial port parameters (baud rate, data bits, parity, stop bits) to match the connected RS232 device. Test communication with a terminal program or a simple echo routine to verify proper transmit and receive paths on both channels.
Usage recommendations
Use proper cable shielding and ground connections where environmental noise is present; verify UART configuration settings on the Pico and the connected RS232 device to ensure matching baud and framing. Avoid exceeding recommended cable lengths and check signal polarity if communication does not occur.
