• UPS Module for Jetson Nano Kit with 18650 batteries
• UPS Module for Jetson Nano Kit without 18650 batteries

Please choose your preferred kit.

This is an Uninterruptible Power Supply module from Waveshare with 18650 batteries. With output voltage of 5V, this UPS module can seamlessly provide backup power for a Jetson Nano board for a safe power management.

Uninterruptible Power

It is able to charge the batteries and provide power output at the same time from external power supply. It automatically switch over to batteries output if external power supply is unavailable, keeps the system running without any trouble.

Product Compatibility

Mounting Holes Are Compatible With Jetson Nano Developer Kit (B01).

Note: The Jetson Nano Developer Kit (B01) is NOT included in the pack.

Pogo Pins Connector

Communicating Via I2C Bus Through Pogo Pins, No Other IO Pin Required.

Real Time Monitoring

Monitoring The Batteries Voltage, Current, Power, And Remaining Capacity Via I2C. When the voltage dips too low, it is possible to save files properly and then soft shutdown the system by software, to avoid any data loss.

Note: if the current value is negative, it means that the batteries are feeding the Jetson Nano. If the current value is positive, it means that the batteries are charging.

Safe And Stable Circuit Design

Protection Circuits For Over Charge/Discharge, Over Current, Short Circuit, And Reverse.Along With The Equalizing Charge Feature, More Safe And Stable.

Longer Battery Life

Supports 4x18650 Batteries.

Hardware:

The 8.4V interface is the charging interface, which uses an 8.4V 2A power supply for charging. 5V OUT is a USB male port that can output 5V power. The 0FF/ON silkscreen is the power switch silkscreen.

Note:

1. Please turn the power switch to OFF before you connect the battery, or the board may be damaged because of shorting. After installing, make sure that the Pogo pins are completely aligned with the pin header before turning on the power. If the Pogo pins are not conducting, you can press the pin to loosen it or use a knife to scratch off the oxide layer of the pin header.
2. The board may not work when you mount the batteries for the first time, you need to press the Boot button to activate the circuit.
3. When connecting the battery for the first time, you need to pay attention to whether the WARNING LED is on. If the LED is on, it means that the corresponding battery is connected reversely. Prohibit charging when the battery is connected reversely
4. It is recommended not to exceed 4A when working for a long time and working with high current. It will heat up when working at 5A for a long time. Pay attention to heat dissipation.
5. To use the power supply configured with the product to charge, using other power sources may cause the product to be damaged due to too large and unstable output power ripple.

Features:

• I2C bus communication, monitoring the batteries voltage, current, power, and remaining capacity in real time
• Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
• Onboard 5V regulator, up to 5A (MAX) continuous output current, more sufficient power source for Jetson Nano
• Batteries warning indicators, easy to check if the battery is connected correctly
• Comes with development resources and manual

Specifications:

• Control bus: 12C
• Output voltage: 5V
• Charger: 8.4V 2A
• Battery support: 18650 Li battery
• Mounting hole size: 2.5mm

Safety cautions:

• Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
• Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
• Do not mix use old batteries with new ones, avoid using batteries of different brands.
• When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
• Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
• Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
