Description

CAN PDB Feature

CAN PDB is an autopilot carrier board developed by CUAV. It integrates the power distribution board, Dronecan intelligent power management system, and autopilot carrier board.

The ultra-thick copper and tin PCB can provide up to 110A of continuous operating current for any device. The self-developed TTI algorithm achieves 0.1A current and 0.05V voltage measurement accuracy comparable to precision instruments.

1.Configurable servo voltage output (5V/7.4V/8.2V), which can power servos with common specifications for unmanned systems.

2.Supports 5V PWM (when K1 is turned on) to improve the anti-interference ability of the control signal.

3.Supports 14~62V voltage input.

4.Accurately measure voltage and current, current accuracy is 0.1A within 110A, and voltage accuracy is 0.05V.

5.Droncan intelligent power management system intelligently monitors battery power, voltage and current.

6.Ultra-thick copper and thickened tin-plated PCB can effectively reduce the heat caused by the internal resistance of the circuit under high current.

7.10 channels of main power output with low voltage drop.

8.Run the TTI algorithm to improve the accuracy of power supply detection under various temperatures.

LED status light

Flashing green: Each battery voltage is 4.0~4.3V
Flashing yellow: The voltage of each battery is lower than 4.0V but higher than 3.7V
Flashing red: the voltage of each battery is lower than 3.5v

Note: Determine the number of battery cells based on the initial voltage. When you power on, the voltage of each LiPo cell is lower than 3.7V, which may misjudge the number of battery cells.

Pinouts

Tip: The pin definition diagram is consistent with the actual interface location.

VOUT and Servo VCC

If you need CAN PDB to power equipment such as fixed-wing servos, please solder JP1, which will connect the VOUT circuit to obtain 5V/7.4V/8.2V power supply.

Note:JP1/JP3/JP4 are disconnected by default. At this time, Servo_vcc (black box in the picture) is an independent circuit and the voltage is 0V. When JP1 is welded, Servo_vcc is connected to the VOUT circuit, and the voltage is 5V; when JP3 is welded, the VOUT circuit voltage becomes 7.4V; when JP3 and JP4 are welded, the VOUT circuit voltage becomes 8.2V.

5V PWM

Tip:If ESC supports 5V PWM, turn on the K1 switch, and the autopilot M1-M8 will output a 5V PWM signal, which can effectively improve the anti-interference ability.

This chapter is applicable to using CAN PDB with ArduPilot flight stack (flight control running ArduPilot firmware).

Enable voltage and current monitor

To enable voltage and current detection, you need to set the autopilot parameters, connect the flight controller to the MissionPlanner ground station, set the following parameters in FULL parameter List, and restart the autopilot after writing:

CAN_P1_DRIVER set to 1
CAN_P2_DRIVER set to 1
BATT_MONITOR set to 8

Parameter

CAN PDB provides 7 parameters for users to set.

BATTERY_ID  // invalid
CAN_NODE_ID  //CAN ID
CELL_SERIES_NUM  //The number of battery cells, the default is 0 (autonomous identification), used to estimate the battery percentage.
CELL_FULL_VOLTAGE //The full-charge voltage of a single battery cell, used to estimate the battery percentage.
CELL_EMPTY_VOLTAGE  //The empty voltage of a single cell is used to estimate the battery percentage.
CALIBRATION_PARAM  //Calibration status identifier. If the value is 1, it has been calibrated (read only and cannot be written).
USE_TMP112  //Temperature sensor, default is 1 (on), set to 0 to turn it off.

Note:The default parameters can meet the needs of most users, do not modify them unless necessary.

Change parameters

Connect the autopilot to the Mission planner ground station, open the Configuration > Optional Hardware > Dronecan/UAVCAN setting interface; click “mavlink-can1” (if connected to CAN1); find the CAN PMU information bar.

Find the parameter settings that need to be modified, save them, and then restart.

High voltage battery settings

Take a 6S battery pack with a battery cell full charge of 4.35v and an empty voltage of 3.3v as an example.

Set the following parameters in the CAN PDB parameter table:

CELL_SERIES_NUM=6
CELL_FULL_VOLTAGE=4350
CELL_EMPTY_VOLTAGE=3300

Click “write params (write parameters)” and restart.

This section applies to CAN PDB with PX4 flight stack (autopilot running PX4 firmware).

Enable voltage and current monitor

To enable voltage and current detection, you need to set the autopilot parameters, connect the flight controller to the QG ground station, set the following parameters in all parameter tables, and restart the autopilot after writing:

UAVCAN_ENABLE set to "Sensor Automatic Config"
UAVCAN_SUB_BAT set to"Raw data"

Change parameters

Connect the autopilot to the QGoundControl ground station, open the Analyze Tools》MAVlink console interface, and send the following commands for configuration:

uavcan status //Get the NODE ID of CAN PDB (you need to press the “Enter” key to send the command)
uavcan param list+[ID] //Read CAN PDB parameter information
uavcan param set + [ID] + [param name] + [value] //Set (modify) parameter values
uavcan param save+[ID] //Save parameters

High voltage battery settings

Take a 6S battery pack with a single cell with a full charge of 4.35v and an empty voltage of 3.3v. The CAN PDB node ID is 49 as an example. Send the following command in the MAVlink console interface:

uavcan param set 49 CELL_SERIES_NUM=6
uavcan param set 49 CELL_FULL_VOLTAGE=4350
uavcan param set 49 CELL_EMPTY_VOLTAGE=3300
uavcan param save 49

Note:If it prompts that the save failed, restart the device and read the device configuration information again to check whether the modification is successful.
