Overview

X306 is a one cell 18650 UPS shield designed for Raspberry Pi Zero W / 2W.

It equipped with 3 standard USB-A 2.0 ports, and a USB Type C to power. The USB-A port can be used to connect external devices such as mouse, keyboard etc.

Do not connect any device to the Micro USB, OTG port of Raspberry Pi Zero 2W when use with X306, or the USB2.0 ports of X306 is not available to use.

Note:

• The Raspberry Pi board, power adapter are not included in the packing list.
• Raspberry pi micro OTG port cannot be used as it is occupied by USB HUB of X306
• Do not connect any device to the Micro USB, OTG port of Raspberry Pi Zero 2W when use with X306, or the USB2.0 ports of X306 is not available to use.

4 Pin header function description:

Pin	Function
AL ON: Pin 1&2	Short: Power always on, power button disabled;
AL ON: Pin 1&2	Open: Power button Press to switch on, Hold 3 seconds to switch off
PWR SW: Pin 3&4	for external 2-pin momentary switch

"AL ON" enable, "PWR SW" will be disable.

"PWR SW" enable, "AL ON" will be disable.

FAQ

Q1. What 18650 battery is recommended?

A: 18650 battery dimension

Q2. What is the power output for each usb port?

A: It is 5V, all ports share 4A, not limited to 500mA.

Q3. Is there any way I can check from the raspberry pi if it's connected to the power or the battery from the UPS?

A: When connected to the power supply to X306, the power supply supplies power to the Raspberry Pi; remove the power supply, it is powered by the battery.

How is the IN-to-SYS pass-through path, to pass the input voltage to the system, implemented and how can I configure and access it?

Hello, 4 blue LEDs on the X306 board indicate battery charging and discharging levels of 25%, 50%, 75% and 100%, read the battery voltage through the Raspberry Pi, we have not tested it, it should not be possible

Is there a way to interface with the UPS from Linux on the raspberry pi? I would like to use NUT to automatically shutdown the system when the battery reaches a certain percentage

Hi, I'm also having the same problem with the USB ports, none of them are working. They are powering things, but no data goes through. I have confirmed the pogo pins are making contact, and have tried using a USB hub on the pi alone, without the UPS, and the hub works fine, so there's something wrong with this UPS. Does it need a ferrite ring?

Would love to solve this issue!

Thanks,

Evan

The USB port of the X306 is a downstream port, which is the same as the USB port of a computer. It can be connected to a mouse, keyboard, and USB disk.

Let's take an example, your computer's USB is connected to your laptop, and what do you wish you could do? Do you want to be able to visit the hard disk of the laptop on the computer? Of course, this is not supported.

Hi,

What about the jumper? I guess if I want to use power switch I have to set it next and in parallel to the USB-Port?

None of the USB ports are working. Anything I plug into them does not function and is not listed as connected. What should I do to fix this?

Hi, we are sending you an email, hoping that you can provide some hardware installation pictures. The products are tested before leaving the factory, and there will be basically no quality problems. I hope you can check the test ponits under the Raspberry Pi Zero 2W, are these test ponits clean and the pogo pins align well with each test pins? This may affect the USB ports which make it not work.

Hello, I'm sorry, we don't have the X306 shell at present, but we have the specific information of X306 PCB dimention File:X306V1.1.dxf, you can make a shell by other means, such as 3D printing

Try to remove X306, then test if the usb hub is recognized?

I'm not sure if the USB ports are being recognized. Is there is software setting I need to change in the pi zero to use the USB ports?
