## Description

## Description ##

The **Kappa4310Rasp is an evaluation board for the IS4310 Modbus RTU Slave chip**. It enables engineers to **easily evaluate the IS4310** without the need for soldering or developing their own prototype, offering a ready-to-use solution. The board features an **RGB LED** and a **push-button** to simulate an actuator and a sensor.

Designed as a shield with the **Raspberry Pi form factor**, the Kappa4310Rasp benefits from its widespread popularity, ensuring compatibility with various single board computers (SBCs), including **Asus Tinker Board, Orange Pi, Rock Pi, Banana Pi**, among others. The board features an **RS485** electrical interface and includes two daisy-chained RJ45 connectors for seamless integration.

The IS4310 is an **ideal solution for ensuring** Modbus protocol timing constraints regarding to the **T1.5 and T3.5 protocol specifications**, reducing CPU load, and eliminating the need for dedicated pins. It includes 500 Holding Registers for engineers to use and supports Function Codes 3 (0x03), 6 (0x06), and 16 (0x10).
