ftSwarm
This controller is the original version of the ftSwarm and is no longer available. Its successor is the more powerful ftSwarmRS. All connections on the JST connectors are protected against reverse polarity. Reverse polarity protection isn’t possible for the signals of the two 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.
