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.

Features

Flexibility

  • Supports 3-6 cell batteries, with stack voltage ranging from 6 V to 26 V

Measurements

  • Performs accurate battery stack and cell voltage measurements as well as accurate battery charge or discharge current measurements, up to 90 A DC

Cell balancing

  • Operates cell balancing during charging

Low power modes

  • Offers a deep sleep mode (for transportation and storage) with very low leakage current, as well as an automatic sleep mode with low current consumption on the battery

Safety

  • Allows diagnostics to verify the safe operation of the battery

CAN

  • Two CAN connectors are available on the board. The board is also compatible with UAVCAN to work with PX4 flight controllers

I²C

  • An I²C interface is implemented on the board and can also be used as an SMBus
  • An external OLED display connected via I²C is provided with RDDRONE-BMS772 kit from rev. 4.0.

NTAG 5 boost

  • The new NTAG 5 boost is embedded on the RDDRONE-BMS772 board. It also allows the user to acquire data and configure the board through NFC

PCB antenna

  • An NFC antenna is built on the PCB. It allows short-range NFC communication with a smartphone

External antenna

  • For extended-range NFC communication, it is possible to install an additional coil as a replacement for the PCB antenna
