How to connect power switch


T201 is a compact one-cell 18650 UPS Shield specially designed for NVIDIA Jetson Nano Developer Kit, it provides smart and powerful uninterruptible power supply and safe power management for Jetson Nano 2GB/4GB.


1. NOT compatible with J010 NANO 4.

2. T201 must be directly connected to Jetson Nano. If T201 does not detect Jetson Nano, it will turn off the power output after a few seconds.

3. AL ON means power always on. When use the exteral power switch, the "AL ON" pin on the T201 must be OPEN.



  • Ideal Uninterruptible Power Supply (UPS) solution for Jetson Nano Developer Kit
  • Max 5.1V 4000mA Power Backup for Jetson Nano
  • With 18650 single cell battery holder
  • Upto 1000mA charging current
  • AC power loss & power adapter failure detection (LED & GPIO)
  • Automatic powering off after system safe shutdown
  • Integrated battery reverse polarity protection circuit
  • Integrated over current protection and over voltage protection
  • Intelligent automatic charging and discharging
  • 4 blue LEDs indicate battery charging and discharging levels of 25%, 50% , 75% and 100%
  • Powers the Jetson Nano via the 40-pin header - no additional cabling required
