RDDRONE-BMS772 Active

Roll over image to zoom in

The RDDRONE-BMS772 is a standalone BMS reference design suitable for mobile robotics such as drones and rovers, supporting 3 to 6 cell batteries.

  • Also suitable for other applications, such as portable medical devices, high energy power tools and personal mobility (wheelchairs / scooters), all of which benefit from from high-quality battery control.
  • Higher voltage cell count applications can rework this reference to daisy chain BCC chips.
  • An S32K144 General Purpose MCU provides great flexibility and communication to a PX4 based FMU via UAVCAN or I²C/SMBus.
