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:

  • BOOKWORM does not require any setup and can be used directly with a keyboard and mouse.
  • 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.

FAQ

Q1. What 18650 battery is recommended?

A: 18650 battery dimension

18650size.png

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.

Does any 18650 battery fit the x306 or is there any recommendation on max discharge current, voltage ?

Is there a gpio pin that tells the raspberry if ups working on battery or power line (as in the x728 hat)?

I see a lot of people knocking this board, i just want to say it's working great for me, I put virtual here server on a pi zero WH and it works amazingly. I can take my portable usb hub out to the garage and plug my laser cutter into it, then go back to my office and burn for a couple hours only using half battery or so. I didn't do anything special.

I was hesitant to buy this product because of some of the comments but I am glad I bought it. It is exactly what I need. I had a spare battery lying around without use, so I needed a UPS hat. The USB hub was a great extra. But, many comments here and reddit posts complained about USB hub not working. I had an impression that it is not working for everyone. But I can confirm, it is working for me. lsusb detects my usb drives (sandisk cruzer blade) and I can mount them. So if you needed a confirmation that this is a working product, you got it. It does work. Both the USB hub and the UPS part. Maybe the other guys had faulty units, dunno.

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

Easy solution, that Geekworm support does not know....

in config.txt comment out: dtoverlay=dwc2

and in cmdline.txt remove: modules-load=dwc2,g_ether

reboot and it works!

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?

Hello, the 4 blue LEDs of the X306 UPS Board indicate battery charging and discharging levels of 25%, 50% , 75% and 100%, can only roughly display the percentage of the battery

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?
