* [https://www.olimex.com/Products/Modules/Interface/MOD-RS232/ MOD-RS232] - | * [https://www.olimex.com/Products/Modules/Interface/MOD-RS232/ MOD-RS232] - TX/RX only. Connect up to two modules to the Board. The connection uses UEXT1 ([[Debug UART/en| Debug UART]] must be disabled) and UEXT2 (cannot be used simultaneously with [[RS-485/en| RS-485]]) | ||
* | * Adapters [[USB-RS-232]]. Up to two cables without using an external USB hub. Possible programmatic [[LAN951x port power control/en|power supply reboot ]] | ||

* https://www.olimex.com/Products/Modules/Interface/MOD-RS485-ISO/ | * 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. | ||
