X306 V1.1 UPS Shield for Pi zero W/2W - Rear View

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.

Only compatible with Raspberry Pi Zero 2W now
Removed 3 standard USB-A 2.0 ports (Users have less need for this. Can directly use OTG port on the Raspberry Pi motherboard)
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

2. GND and PSW are pins for external reset/momentary switch

Overview

X306 is an ultra-thin one cell 18650 UPS shield designed for Raspberry Pi Zero 2W.

Features

Key Features	Ideal Uninterruptible Power Supply (UPS) solution for Raspberry Pi Zero 2W (X306 V1.1 support Pi Zero W also, but X306 V1.3 only support Pi Zero 2W) Max 5.1V 4000mA Power Backup for even the most demanding Raspberry Pi set ups 18650 single cell battery holder (Use 3.7V 18650 battery) Upto 1000mA charging current Integrated battery reverse polarity protection circuit Integrated over current protection and over voltage protection Intelligent automatic charging and discharging 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 Connects to the Raspberry Pi via Pogo Pins - no wirindg & soldering required 4-pin header for external power swtich and always-on power option (Removed from X306 V1.3) Equipped with three USB2.0 ports and one USB2.0 4-through-holes for more USB expansion (Removed from X306 V1.3)
Specification	Input supply voltage: 5Vdc +/-5% Input supply current: ≥3A Charging current: 900~1050mA Trickle charge current: 130~140mA Predetermined Charge voltage: 4.2V +/-1.5% Output voltage: 5.1V +/-5% Max output current: 4000mA
Notes	BOOKWORM does not require any setup and can be used directly with a keyboard and mouse. 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.

How to Power

Power Input: 5.1Vdc +/-5% , ≥3A (Power Via USB Type-C port of X306 NOT Pi zero 2W)

FAQ

Q1. What 18650 battery is recommended?

A: 3.7V flat top 18650 battery is required. 18650 battery dimension is as follow

Please use high quality batteries from Samsung 35E 18650 lithium battery, Panasonic NCR18650B, Toshiba, etc. Do not use the battery with built-in protection circuit because it will limit the discharge current.

Q2. What is the power output for each usb port of X306 V1.1 Version?

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.

Q4. No data on the usb ports？

A: There is a feedback from buyers that solved this problem. Please refer to go to:X306#comment-4545

in config.txt comment out: dtoverlay=dwc2
and in cmdline.txt remove: modules-load=dwc2,g_ether
reboot and it works!
