==Updated==

X306 is updated to V1.5 version on August 21st 2025: A higher-quality 18650 battery holder is used, making battery installation and removal easier and more robust.

~~==Updated==~~X306 is ~~~~updated to V1.3 on May 28th, 2024.~~~~

Please check the information on the page on the sales platform to confirm the version you will get.

* Removed 4-pin header for external power swtich and always-on power option(Users have less need for this. Can can solder it yourself if needed)

* Smaller size, simplified use

[[File: X306-V1.3-IMG-8223-compare.jpg|700px]]

* 4 blue LEDs indicate battery charging and discharging levels of 25%, 50% , 75% and 100%

* Red & green LEDs show the status of power on/off and charging status

* On-board push button to control power on /off ('''Press-ON, Hold the button pressed at least 3s -OFF''')

* Ultra-low standby power consumption of μA to maximize battery life

* Advanced system power path management avoids frequent charging and extend battery life

* When use with X306 '''V1.1''', '''DO NOT''' connect any device to the Micro USB OTG port of Raspberry Pi Zero 2W, or the USB2.0 ports of X306 is not available to use.

==Matching Case==

The Geekworm X306-C1 is a premium metal case specifically designed for use with the Raspberry Pi Zero 2W and Geekworm X306 V1.3 UPS board. Crafted with precision and durability in mind, this case provides a sleek and protective housing for your Raspberry Pi Zero 2W project.

===Test of the impact of the casing on WiFi signals===

It should be noted that the metal shell will have a certain shielding effect on WiFi, and the farther the device is from the router, the greater the effect will be.

We tested the effect of metal casing on Wi-Fi signal, and the results are as follows:

'''WiFi signal strength reference range'''

-30 dBm to -60 dBm: Very strong signal (close to the router).

-60 dBm to -70 dBm: Good signal (suitable for daily use).

-70 dBm to -85 dBm: Weak signal (may affect speed or stability).

<-85 dBm: Extremely poor signal (difficult to connect or frequently disconnects).

'''Test subjects''': X306-C1 metal case

'''Test Method''': We flashed the Raspberry Pi OS Legacy (6 May 2025) version and used the script [[File:Wifi-signal-monitor.zip]] (download and unzip it) to obtain the WiFi signal strength with and without the X306-C1 metal case.

'''Other notes''': The Raspberry Pi Zero 2W motherboard is about 3.5 meters away from the router, with no obstructions in between. Use the script wifi_signal_monitor.sh to test

'''2.4GHz or 5GHz frequency band''' :Since the Raspberry Pi Zero 2W only supports the 2.4GHz IEEE 802.11b/g/n WiFi band, you can only access 2.4GHz SSID hotspots.

Based on the above test results, we can draw a conclusion: X306-C1 can meet the needs of devices using 2.4GHz Wi-Fi '''when close to the router''', which should be attributed to the larger heat dissipation hole design on the surface of the X306-C1 shell.
