CAN PDB
CAN PDB is a controller carrier board developed by CUAV, integrating a power distribution board, Dronecan intelligent power management system, and controller carrier board functions.
The ultra-thick copper-tin PCB can provide a continuous operating current of up to 110A for host devices, and the self-developed ITT algorithm achieves current measurement accuracy of 0.1A and voltage measurement accuracy of 0.05V, comparable to precision instruments.
Product Features
- Equipped with 12V/4A output and configurable BEC output (5V/7.4V/8.2V) to power servos and devices of common specifications in unmanned systems.
- Supports 5V PWM signals (when the K1 switch is turned on) to enhance the anti-interference capability of control signals.
- Supports 14~60V voltage input.
- Accurately measures voltage and current; current accuracy reaches 0.1A within the 110A range, and voltage accuracy reaches 0.05V.
- Dronecan intelligent power management system can intelligently monitor battery capacity, voltage, and current.
- Ultra-thick copper foil and thickened tin-plated PCB can effectively reduce heat generated by circuit internal resistance under high current.
- 10 channels of main power output with low voltage drop.
- Runs the ITT algorithm to improve the accuracy of power detection under various temperature conditions.

Size
LED Status Light
- Blinking Green: Voltage of each battery cell is 4.0~4.3V
- Blinking Yellow: Voltage of each battery cell is lower than 4.0V but higher than 3.7V
- Blinking Red: Voltage of each battery cell is lower than 3.5V
NOTE
The number of battery cells is determined based on the initial voltage. When powering on, if the voltage of each LiPo cell is lower than 3.7V, it may cause misjudgment of the number of battery cells.
Pinouts
TIP
The pinout diagram matches the actual interface positions.
VOUT and Servo VCC
If you need the CAN PDB to power devices such as fixed-wing servos, solder JP1. This will connect the VOUT circuit to obtain 5V/7.4V/8.2V power supply.
NOTE
JP1/JP3/JP4 are disconnected by default. In this state, Servo_VCC (the black box in the image) is an independent circuit with a voltage of 0V. When JP1 is soldered, Servo_VCC is connected to the VOUT circuit, and the voltage is 5V; when JP3 is soldered, the VOUT circuit voltage becomes 7.4V; when both JP3 and JP4 are soldered, the VOUT circuit voltage becomes 8.2V.
5V PWM
TIP
If the ESC supports 5V PWM, turn on the K1 switch. The controller’s M1-M8 will output 5V PWM signals, which can effectively improve anti-interference capability.
