==Overview==
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.
