-The %%Pmod RS232%% communicates with the host board via the [[pmod:communication_protocols:uart|UART protocol]]. The arrangement of the pins is the [[pmod:communication_protocols:uart:old_vs_new|old UART]] communication style (Type 3 in the [[https://www.digilentinc.com/Pmods/Digilent-Pmod_%20Interface_Specification.pdf|Digilent Pmod Interface Specification]]) so that a crossover cable will be required if attaching this Pmod to one of the dedicated UART Pmod headers on any of the newer Digilent microcontroller boards. For a list of which MCU boards use the old UART protocol, see our explanation [[https://reference.digilentinc.com/_media/pmod:pmod:connecting_uart_pmod_interfaces.pdf|here]].+The %%Pmod RS232%% communicates with the host board via the [[pmod:communication_protocols:uart|UART protocol]].
