The PBR-12X is a compact 12-channel expander designed for models with limited space, such as F5J and F3B gliders. It features an integral electronic switch operated via the MicroSwitch or by connecting the battery, storing the last switched state. The unit includes a high-current MR30 input and an MR30 to MPX adapter, supporting any receiver with a bus output and automatically detecting the connected bus system. It enables redundant receiver setups, seamlessly replacing lost data packets from the first receiver with data from the second. The PBR-12X also supplies telemetry data including battery voltage, current, consumed capacity, and reception data to compatible radio control systems.
