ftSwarmRS
This controller is the slightly more powerful successor to the ftSwarm and ftSwarmRS. All connections to the screw terminals are protected against reverse polarity. Reverse polarity protection is not possible for the signals on the pin headers.

Power Supply
The device needs an external 9V power supply. Using USB power only you could flash your program or firmware but the IO’s won’t work correctly.
An onboard 2A PTC fuse limts the device max. power budget. If you use all actor options, you need to calculate your power budget.
