Orbit Network Power Supply Requirement s All Orbit Modules are designed to work from a supply voltage of 4.75V to 5.25 Vdc. When power is applied to a module its current consumption will cause a slight voltage drop across cables. Care must be t aken to ensure that all modules have the right working voltage applied. This section is for guidance only[...]
