# Manifold 5S Smart Switch

The Manifold 5S includes an onboard Linux-based CPU that enables additional connectivity and features compared to the Manifold 5L:

* Supports Cerulean Sonar SonarLink software
* Supports Cerulean Sonar SonarView software
* Adds two serial ports, one with optional CTS/RTS hardware handshake.
* Adds two USB ports.
* Adds two I2C ports.
* The serial ports and USB ports have drivers to integrate the Cerulean S500C single beam echo sounder (SBES), Cerulean Sonar ROL Locator, Blue Robotics Ping2 SBES, generic GPS, and more.
* Each serial or USB port can also be configured to forward incoming data via UDP packets.
* Each serial or USB port can be also configured to replicate the port I/O via UDP over Ethernet, which is supported by 3rd-party port replicators.
* The I2C ports can be configured to support one of the Blue Robotics BAR30, BAR02, and BAR100 pressure/temperature sensors, forwarding readings to an ArduSub device on the network via a MAVLink REST service.

If used on a BlueROV, the Manifold 5S requires net zero penetrator holes in the main electronics enclosure by moving the BAR30 pressure sensor to the Manifold 5 and connecting the Manifold 5S to the ROV using the former BAR30 hole.
