The biggest advantage of R1BBIT boards is the built-in lightweight scripting language similar to Basic. It includes syntax checking, color highlighting of data and operators for easy coding and debugging. This advantage is so significant that we will describe it in detail in the software section, covering its operators, ways to interact with the board, and how to run scripts directly on the device.
Easy control from a mobile app or desktop software.
