SparkFun AST-CAN485 Dev Board

Description

The SparkFun AST-CAN485 Dev Board bridges the gap between maker and industrial applications, offering a powerful, compact solution built around the Atmel AT90CAN128 processor. This board delivers 16MHz operation with 128kB Flash and 4kB SRAM, making it suitable for a wide range of embedded projects. Its pin-compatibility with the Arduino Pro Mini ensures a small footprint, ideal for integration into space-constrained designs.

Key to its functionality are the integrated CAN and RS485 transceivers, enabling out-of-the-box interfacing with industrial devices and networks without additional shields. The board supports the Arduino IDE and its vast ecosystem, facilitating ease of use and rapid prototyping. It provides comprehensive peripheral support including I2C, SPI, 2 UARTs, 8 analog inputs, and 6 interrupt-enabled pins. An onboard voltage regulator allows for a flexible input voltage range of 7-16V, with 7-12V recommended for stable operation.

Leveraging CAN and RS485, the AST-CAN485 is a versatile platform for applications in automation, industrial control systems, building management, automotive diagnostics (OBDII), and various other communication-intensive embedded projects.
