4 Uarts and 2 Ethernet possiblities

(04-04-2019, 12:20 PM)gops Wrote: 1. We need 4 UARTs

Is it possible to enable some GPIO pins to be UART? We want to connect 4 RS 485 channels on 4 UARTS

On the GPIO header, there is only the UART2DBG.
What I suggest you is to build a piggy back board with 2 SC16IS752, which is a Dual Uart chip attached on SPI bus, that way, you will get 4 GPIO with HalfDuplex capability for RS485.
