Electrical Ratings
The xCore board is designed be powered easily. Below are the detailed electrical specifications based on the power and logic requirements of these components.
Power Supply
- Input Voltage: 5V DC
A 5V power supply with a minimum current rating of 3A is recommended to ensure smooth operation, even under load. - Power Consumption:
- Idle: 600mA @ 5V
- Under Load: Up to 3A @ 5V (depending on connected peripherals and CM4 load)
- Logic Level (I/O Pins): 3.3V
The xCore board’s logic operates at 3.3V. - 3.3V Rail Maximum Current: 500mA
The 3.3V rail is suitable for low-power peripherals and provides up to 500mA.
