Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/DFR0494:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description *We recommend [the 18650 Pi 5 UPS HAT](https://core-electronics.com.au/raspberry-pi-5-18650-battery-ups-hat-51v-5a.html) for the [Raspberry Pi 5's](https://core-electronics.com.au/raspberry-pi/raspberry-pi-5-boards-kits-and-accessories.html) additional power draw.* DFRobot Raspberry Pi UPS HAT is an uninterruptable power supply shield for Raspberry Pi. It can provide a steady power source to [Raspberry Pi](https://core-electronics.com.au/raspberry-pi.html) for an extended period of time when the system is powered-off, by which to avoid system damage and assure safe shut down. In addition, the product could be used to supply stable power for some applications requiring mobility such as Raspberry Pi camera, tablet PC, field data collection system. A MAX17043 fuel gauge is adopted in this product for accurate power detection. Besides, we also employ an on-board microcontroller (MCU) for data processing. In this way, the Raspberry Pi board is able to get information of power capacity and battery voltage directly via I2C communication. 5 on-board LEDs for the shield could show the status of the battery capacity visually without programming. We adopted an excellent power management solution in this Raspberry Pi UPS HAT. Over 90% power conversion efficiency and non-dioded design make the shield able to keep the low heating temperature even under continuous high load operation of Raspberry Pi. When the battery power is lower than 5%, the 5V power output to the Raspberry Pi will be cut off automatically. When the charger is plugged in and the battery power increases to 7%, the 5V power supply will restart automatically. **Notes** - 3.7V Lithium Battery is not included in the package due to transportation constraints - Please use 3.7V Lithium Battery that meets the standard specification - Please note that there would be a certain degree of heating in the power source area of the product during operation, you can never be too careful in use. ### Features - Standard Raspberry Pi extension interface, compatible with other expansion boards - Support 2A maximum current output, suitable for most Raspberry Pi applications - Auto switching of charge/recharge path, designed to against power-down - On-board 5 LEDs for showing the batteries’ status - On-board Maxim fuel gauge IC - Support reading battery information via I2C communication - Lithium battery charge/discharge protection and over-heating protection - Anti-backflow mainboard power source ### Specs - Supply Voltage: 4.5~5.5V - Supply Current: (recommend using adapter with power of 2A and above) - Power Supply Interface: Micro-USB - Maximum Charge Current: 1.6A - Battery Interface: PH2.0-2P or solderable contact - Battery: 3.7 Lithium Battery - Output Voltage: 5V - Maximum Output Current: 2A - Communication Interface: I2C - Dimension: 65mmx56mm/2.56”x2.20” - Mounting Hole Size: 58mmx49mm/2.28”x1.93” - Operating Temperature: -40℃~85℃ ### Documentation - [Wiki page](https://wiki.dfrobot.com/Raspberry_Pi_UPS_HAT_SKU_DFR0494) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/d/f/dfr0494-detail-002_564x376.jpg)
