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. [[File:X306-C1-IMG-97429736-Packing-List.jpg|700px500px]] ===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: '''Test Result:'''{| class="wikitable"!

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.
