General description

Introduction

The Würth Elektronik eiSos Serial(RS232/RS485) bridge FeatherWing is a development board that acts as a bridge between UART and RS232/RS485/RS422. It is fully compatible with the popular Adafruit Feather line of development boards and can be used as a plug-and-play solution to connect any D-SUB9 interfaced device to the Feather ecosystem. This FeatherWing acts as a bridge between legacy RS232/RS485 devices and modern wired/wireless digital interfaces.

Functional description

• The Serial(RS232/RS485) bridge FeatherWing was designed with rapid prototyping in mind. Being fully compatible with the Adafruit ecosystem, this FeatherWing allows the user the flexibility to choose the preferred host microcontroller.
• The inherent modularity of the ecosystem allows the FeatherWing to be easily integrated into any project. The next sections provide a brief introduction to Adafruit’s Feather ecosystem and details on the power modules.
• Feel free to check our YouTube channel: www.youtube.com/user/WuerthElektronik/videos for video tutorials, hands-on and webinars relating to our products.

Adafruit Feather

• Feather: Adafruit Feathers are a complete line of development boards from Adafruit that are standalone and stackable. They can be powered either over the on-board micro-USB plugs or using a Li-Po battery.
• Feathers are portable, flexible and light as their namesake.
• FeatherWing: FeatherWings are stackable boards that when used along with a Feather add a certain functionality to the system.
• The Adafruit Feather ecosystem consists of two types of boards apart from a host of acces-sories:
• The Feather system with more than 50+ Wings, several different types of accessories and Arduino/circuit python-based code support, provides a perfect ecosystem for rapid prototyping.
• Please refer to adafruit.com/feather for more details on the Adafruit Feather ecosystem.

• Accordingly, the customer is cautioned to verify that the documentation is current before placing orders.

Customer responsibility related to specific, in particular safety-relevant applications

It has to be pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be eliminated in the current state of the art, even if the products are operated within the range of the specifications. The same statement is valid for all software source code and firmware parts contained in or used with or for products in the wireless connectivity and sensor product range of Würth Elektronik eiSos GmbH & Co. KG. In certain customer applications requiring a high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health, it must be ensured by the most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component.

Best care and attention

• Any product-specific data sheets, manuals, application notes, PCNs, warnings and cautions must be strictly observed in the most recent versions and match the product’s firmware revisions.
• These documents can be downloaded from the product-specific sections on the wireless connectivity homepage.

Customer support for product specifications

• Some products within the product range may contain substances, which are subject to restrictions in certain jurisdictions to serve specific technical requirements.
• Necessary information is available on request. In this case, the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.
