2-Channel CAN-Bus Dual Chip HAT for Raspberry Pi

The 2-channel CAN bus expansion HAT for Raspberry Pi is a versatile extension for your Raspberry Pi system, perfect for industrial applications and projects that require reliable CAN bus communication. With this HAT, you can use up to two CAN channels simultaneously, with communication being particularly safe and stable thanks to electric isolation. Thanks to the stackable design, you can combine multiple of these HATs to expand additional CAN channels. The integrated protection circuits, including ESD protection and transient peak voltage protection, ensure robust operation. The HAT supports a wide power supply from 7 to 36V, making it particularly flexible. Reliable and fast CAN communication is ensured by the use of dual chips (MCP2515 and SN65HVD230). With detailed online resources and examples in Python and C, you can quickly and easily get started with your project.
