On page 12 (p.15 of the PDF) of the Discover WiFi User Manual V1.5, it shows four connections from the WiFi module to the STM32F4 Discovery, the J6 connections are obvious. PC10 and PC11 on the Discovery board are depicted as connecting to RXD and TXD respectively on a USB to Serial block which contains no jack or pin numbers. The resolution of the embedded picture isn't high enough to be sure which pins those are. Can someone tell me where RXD and TXD are - preferably in a support document of some kind? Thanks...
