OSP Controller

The OSP Controller is a compact interface and power management module designed to support communication over the Open Serial Peripheral (OSP) protocol. OSP is a lightweight communication protocol based on fixed-size data frames transmitted over an RS232 serial interface, enabling deterministic and efficient data exchange between connected devices.

A key feature of the OSP protocol is its support for a ring (daisy-chain) topology, allowing multiple nodes to be connected sequentially through a single controller. This architecture simplifies wiring, reduces the number of required interfaces, and enables scalable system expansion without complex network infrastructure.

The OSP Controller integrates:
- A USB-to-serial interface (FT232) for communication with a host system
- A DC-DC step-down converter for stable power distribution
- A dedicated COM interface (JST XH 6-pin) for connecting OSP nodes

The controller acts as a bridge between a host computer and the OSP network, handling si
