Review on 🔌 FL RS232 Global Cache SL by Adam Ross

Works as expected; Read the specs before purchasing as there are some limitations. The Flex series is generally really good and this is no exception. Cons: No response buffer on consecutive calls. (Debugging for customization is possible by connecting RAW to the 4999 port of the ribbon cable from the debugging PC) Powered by USB 5V [flexible], if 5V is already available locally, an additional connector is required. Pros: direct HTTP control (one-way AJAX device control) NULL/direct on-the-fly replacement via configuration. Very simple design
