RS232 Transceiver Module for Raspberry Pi Pico - 2 Channel, UART

For anyone who’s been fortunate enough to get their hands on and experiment with the tiny but versatile Raspberry Pi Pico, you’ll understand that the Pi Pico is ready to provide a great platform for versatile Pi projects, taking on the form of a microcontroller rather than a single board computer, and ready for a surprisingly versatile level of functionality. This is why we’re already on the lookout for cool expansion modules for the Pi Pico, such as this RS232 Transceiver Module for Raspberry Pi Pico, which is 2 Channel, communicates via a UART bus, and fits directly onto the top of a Raspberry Pi Pico like a Pi HAT or Arduino Shield does for the larger sized boards. Once plugged in, this module allows for simplified RS232 communications from your Raspberry Pi Pico, with two channels so that you can control or interface with two different systems, machines or other devices simultaneously.

In addition to a simple and easy to use style, this module offers sheer convenience, with both 3-pin interfaces as well as screw-in terminals for connecting with various cables, and Waveshare have even included a handy DB9 to 3PIN adapter cable so that you can set it up and get started with minimal effort and without even having to get any special cables to make it work. So if you’ve been eyeing out the Raspberry Pi Pico, but have been waiting for a simplified or easier way to get it to operate with RS232 devices and systems, you can finally take the leap and get yourself a nice little Pi Pico along with this handy Pi Pico Expansion – or PicoHAT for short.

Please Note: When looking at the side of this board opposite to the screw-in terminals, you will notice a small “USB” label on one end. Make sure to plug your Pi Pico in so that the USB Port on the Pico is on the same end as the USB label on the expansion board. This will ensure safe operations and eliminate any potential for damaging either board.

When it comes to producing unique electronics components and modules, there are very few brands that can provide the quality that Waveshare can. Based in the Futian District in Shenzhen, China, Waveshare are experts in developing electronics to a high standard of quality, which have been thoroughly tested to work seamlessly with corresponding development platforms and systems – such as the E-Ink HATs for Raspberry Pi’s.

What we love most about Waveshare is how they are dedicated to providing quality products, and have moved away from the typical “Made in China” stigma – cheap products with cheap parts and components. Instead, Waveshare understand the value of supplying quality products and building sustainable relationships with international resellers and distributors. They know that consistent quality will result in consistent business, and as such they always ensure strict quality control for each and every product that comes out of the manufacturing plant.

We are always excited to peruse through their vast catalogue of exciting new products to find unique modules, components or even entire development boards that are designed with quality in mind. Because we know that every cent that we spend with Waveshare will be well-spent, with each product that order adding real value to our own catalogue of products.
