Description
Description
This industrial-grade expansion board is designed specifically for Raspberry Pi 4B and Raspberry Pi 5, adding a range of isolated communication interfaces: 2x RS485, 1x RS232, 1x CAN FD, and 1x CAN. With its durable build, it includes features like surge and electrostatic protection, making it ideal for secure, reliable industrial applications.
Features
- Multi-Protocol Support: Provides 2x RS485, 1x RS232, 1x CAN FD, and 1x CAN interfaces, each with electrical isolation.
- Robust Protection: Equipped with TVS surge protection, ESD protection, and self-recovery fuse to ensure stable and protected operation.
- Industrial-Grade Enclosure: Comes with a wall-mount and rail-mount compatible plastic case, providing extra space for HAT stacking and PCIe adapter expansion.
- Wide Compatibility: Compatible with Raspberry Pi 4B and 5, uses the 40PIN GPIO header and supports further stacking of HATs without pin conflicts.
- Multiple Power Options: Offers a Type-C 5V port and a 7-36V screw terminal, supporting both typical Raspberry Pi power supplies and industrial power scenarios.
- Enhanced Interface Isolation: Integrates digital isolation chips for stable, interference-resistant operation.
- Flexible Interrupt Configuration: Reserved interrupt resistor pads allow for easy switching of the interrupt pin for compatibility with other HATs.
