Geekworm X306 V1.3 18650 UPS Expansion Board for Raspberry Pi Zero 2W

Update History

X306 is updated from V1.1 to V1.3 on May 28th 2024. 

1. Only compatible with Raspberry Pi Zero 2W now
2. Removed 3 standard USB-A 2.0 ports (Users have less need for this. Can directly use OTG port on the Raspberry Pi motherboard)
3. Removed 4-pin header for external power switch and always-on power option(Users have less need for this. Can can solder it yourself if needed)
4. Smaller size, simplified use

Note: The Raspberry Pi, 18650 battery & heatsink is not included in the packing list.
