Connect a UART/RS232/IrDA to a Trizeps

Applies to: Trizeps IV(M), Trizeps IV WL, Trizeps V, Trizeps VI.

Schematic

FFUART (COM1) to RS232

This is a sample on how to connect COM1 to a DSUB9-RS232 connector. Like almost all of the Trizeps-signals, the COM1-pins are only +3V3-tolerant.

BTUART (COM2) to RS232

This is a sample on how to connect COM2 to a 10pol. header. This 10pol-header allows easy connection to a RS232-SUBD connector. Of course you may connect the UART-ports with +3V3-compatible hardware directly, i.e. serial-bluetooth-modules or printers.

STUART (COM3) to IrDA

This is a sample on how to connect COM3 to an IrDA transceiver. On Trizeps4 and Trizeps5 only COM3 can be configured as IrDA. Of course it can be configured as normal UART too.
