Loco Positioning deck

The Loco Positioning deck is designed to be installed on the Crazyflie 2.0 deck port. The orientation is indicated using the standard deck orientation symbol. The UWB antenna is facing up on the front of the Crazyflie.

The deck contains a row of 4 LEDs, all controlled by the DWM1000:

  • TX: Transmitting
  • RX: Receiving
  • SFD: Received packet timestamp
  • RXOK: Packet received without error


The firmware for the DWM deck is included in the Crazyflie 2.0 firmware build (recent) and activated when the deck is attached. The deck contains a small memory that holds the address of the board as well as the addresses of the anchors it will use for ranging.

More information on building the firmware and the firmware itself can be found here.
