| The TCB has two general purpose I/O ports called A & B. Whether they operate as inputs or outputs is something you determine by a setting on the [[wiki:opconfig:tabs:lightsio|Lights & I/O tab]] of OP Config. If set to input, then the following functions will not appear. When set to output remember these ports only provide a //logic-level// on/off signal at 5 volts with a 20mA max current draw each. This means they can be connected to another 5-volt tolerant microcontroller or logic circuit, but they should not be used to drive lights or other devices directly. The TCB has four light outputs plus the Aux Output that are better suited to driving devices. However if those are not enough you can still use these to drive a transistor or MOSFET circuit which itself can then drive a light or LED. See the [[wiki:tcb:tcbinstall:io_ports_ab|I/O Ports]] page for more information. | The TCB has two general purpose I/O ports called A & B.

If set to input, then the following functions will not appear. When set to output remember these ports only provide a //logic-level// on/off signal at 5 volts with a 40mA max current draw each. This means they can be connected to another 5-volt tolerant microcontroller or logic circuit, but they should not be used to drive lights or other devices directly unless you are certain the current draw will remain under 40mA.
