NVIDIA Jetson Nano 3-Ch Relay HAT expansion card (19075)

TheNVIDIA Jetson Nano 3-CH Relay Module HAT (19075 ) is designed to control the on/off of power circuits, allowing you to use the Jetson Nano to control home appliances.

Features of the board:

• Standard 40-pin GPIO connector that connects directly to the Jetson Nano
• Relay component with maximum load: ≤5A 250 VAC or ≤5A 30 VDC
• Optocoupler insulation for more stable board operation
• Built-in indicators to monitor the operating status of the relay
• Relay control contacts are configured using jumpers.
• Acrylic bottom panel that isolates the Jetson Nano from the expansion board with the relay
• Comes with development resources and user manual (python and python-bottle examples)

An example of connecting to Jetson Nano:

The purpose of the board elements:

1. 40PIN GPIO connector
2. Relay screw terminals
3. relay components
4. optocouplers
5. Relay operation indicators
6. power indicator
7. Relay control contact jumpers

Thanks to the jumpers and operating indicators, it is easy to visually monitor the relay's operating mode. The indicator LEDs light up when the relay's normally open contact is closed and go out when the normally open contact opens and the relay's normally closed contact closes.

Optocouplers protect the low-voltage control elements of the board from the effects of power elements.

A protective cover plate protects against contact with high-voltage elements.

Purpose of the connectors:

3.3V power supply - 3.3V supply voltage

5V power supply - 5V supply voltage

Ground

Channel 1 - Channel 1

Channel 2 - Channel 2

Channel 3 - Channel 3
