This 2-channel RS232 module is designed specifically for the Raspberry Pi Pico. It incorporates the SP3232EEN RS232 transceiver and uses the UART bus. Key features include a standard Raspberry Pi Pico header, supporting the entire Raspberry Pi Pico series. With the UART bus, it can easily convert UART to RS232 and vice versa. It comes with comprehensive development resources and a manual, including Raspberry Pi Pico C/C++ and MicroPython examples. The operating voltage ranges from 3.3V to 5V. It has an onboard female pin header for direct attachment to the Raspberry Pi Pico (note that the Raspberry Pi Pico is not included). On - board components are the SP3232 RS232 transceiver, a Raspberry Pi Pico header, an RS232 bus interface with 2 - channel RS232 (a DB9 male connector is available via an adapter cable), TVS and ESD diodes, and UART status indicators. You can find more information on the WIKI: Pico - 2CH - RS232.
Using this 2 - channel RS232 module with your Raspberry Pi Pico is quite straightforward. First, make sure your Raspberry Pi Pico is powered off. Then, attach the module to the Pico using the onboard female pin header. After that, you can power on the Pico. The module can easily convert UART to RS232 or the other way around, so you just need to connect your devices according to your communication needs. When using the module, remember that the Raspberry Pi Pico is not included in the package. Also, the operating voltage should be within the 3.3V - 5V range to avoid damaging the module. For maintenance, keep the module in a dry and clean environment. If you face any issues, you can refer to the development resources and manual that come with the module. There are also examples in Raspberry Pi Pico C/C++ and MicroPython. And don't forget to check the WIKI: Pico - 2CH - RS232 for more detailed information.
