T208 PCB Size


T208 is the upgrade version of T200, supports upto 6-cell 18650 battery, can provide enough power supply for your outdoor scientific research. We no longer use cable connections and use new and more reliable GPIO connections.

The T208 is an advanced uninterruptible power supply (UPS) expansion board specially designed for NVIDIA Jetson Nano Developer Kit. It provides Max 5.1V 8000mA Power Backup for even the most demanding Jetson Nano set ups, intelligent & safe power management, AC power loss/ power adapter failure detection, auto power-on, full poweroff from software, advanced system power path management, i2c & LED fuel-gauge systems, and with 6-cell 18650 battery holder.


T208 V1.2 is released on 10th Augest, 2021, only added input surge protection circuit.


  • You must read these safety instructions and warnings before charging your batteries.
  • Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly.
  • Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery's connector to make sure "+" to "+" and "-" to "-".
  • Do not mix and use old batteries and new batteries, or batteries with different brand names.
  • Lithium batteries has it's cycle life, please replace old battery with new one when it reaches it's service life or when it is two year old, whichever comes first.
  • When charging Battery Pack, please put battery in a fire proof container. Please don't leave the X728 on the wood material or carpet and unattended.
  • Must keep the T208 away from children.
  • Please watch Main Video and Tutorial Video regarding 18650 batteries at: https://www.staysafebattery.com/en/

Dear support,

is it possible to use the max. provided 8A with the XH2.54 power outputs only? With amount of current can be provided by one XH2.54 power output? Thank you very much!

Hi,The total of XH2.54 5V outputs is 8A, each output value depends on your load situation.

Is there a way for the Jetson Nano to know if the T208 powered, do this information is transmitted on I2C or the PIN 7 (GPIO6)? Except checking if the voltage is increasing. And what is the purpose of the pin10 (IO8)?

Can I supply the power from the T208 to Jetson Nano via a 3-pin female/female cable?

Hi,dear,Glad to receive your message,but sorry to tell it is not available to power via a 3-pin cable. As the there are ten PINs in T208. Except NC pin is not required, all others must be used. Please refer to the PIN schematic picture below.T208-Pin schematic picture.jpg

Jetson Xavier requires 19V power supply, so this will not be enough
