Different screens and displays can be connected via serial interface. Connection of character screens in parallel mode is also supported.

Many displays are supported by the driver https://github.com/notro/fbtft , which is not yet integrated into the mainline kernel. List of supported driver models: https://github.com/notro/fbtft/wiki/LCD-Modules

Below is a list of screens tested with Wiren Board.

2.2’ TFT LCD: TFT01-2.2 SP from Elecfreacs and clones, 320x240 color, chip ILI9341,starting from $6.5 at retail

MOD-RS232 - TX/RX only. Connect up to two modules to the Board. The connection uses UEXT1 ( Debug UART must be disabled) and UEXT2 (cannot be used simultaneously with RS-485)
Adapters USB-RS-232. Up to two cables without using an external USB hub. Possible programmatic power supply reboot

https://www.olimex.com/Products/Modules/Interface/MOD-RS485-ISO/ galvanically isolated, full/half duplex, I2C interface, can be used in conjunction with Debug UART and RS-485. It is possible to connect more than two devices.
https://www.olimex.com/Products/Modules/Interface/MOD-RS485 - half duplex, uses UART. Up to two modules.

Connect the lines D0 and D1 of the readers to the GPIO through a resistor 1-20 kom! (on Wiren Board 2.8)
