Product Profile The BIGTREETECH PANDA PWR is a power management and control device for printers. It powers the printer and displays real-time power on the PANDA TOUCH, also enabling on/off control via a WiFi connection with PANDA TOUCH. Additionally, the PANDA PWR features a USB port to power the PANDA TOUCH directly. 1.1. Specifications MCU: ESP8684-MINI-1-H4 IEC-C14 Input Voltage: 100VAC~240VAC Type-C Input Voltage: 5V Maximum Output Current: 1.5A+1.5A PC Connection Interface: Type-C 1.2. Dimensions BIGTREETECH PANDA PWR User Manual 5 2. Interface 2.1. Interface Diagram 2.2. Interface Introduction IEC-C14: AC voltage input of 100VAC~240VAC IEC-C13: AC voltage output of 100VAC~240VAC, rated load current 3A TYPE-C: 5V input, can communicate with a computer USBA: Two 5V/1.5A outputs 3. Instructions 3.1. USB Interface 3.1.1. USB1 (5V Output, Controllable) Used for modules that require control switches, such as a USB light strip. 3.1.2. USB2 (Fixed 5V Output) Can provide power to some modules, such as Panda Touch. 3.2. Bind Key 3.2.1. Bind a Panda Touch Long press for several seconds to enter the binding mode. 3.2.2. Activate the 220V Power Supply Activate the 220V power supply by double-clicking the Bind key. 3.3. Web UI 3.3.1. View Power Parameters Before proceeding, you must bind a Panda Touch, obtain the IP address from the Panda PWR interface, and then enter the IP address in your computer or mobile BIGTREETECH PANDA PWR User Manual 7 browser. 3.3.2. OTA Click the "Config" button to enter the OTA page. BIGTREETECH PANDA PWR User Manual 8 Click the "Select File" button to update the firmware. After the upgrade is completed, a success prompt will be displayed. BIGTREETECH PANDA PWR User Manual 9 3.4. How to Bind Panda PWR and Panda Touch Open the Panda PWR page. Bring Panda PWR and Panda Touch Closer Together Press and hold the bind button for about 3 seconds, wait for the light to turn blue and enter a breathing state, then wait for a pop-up prompt to appear and click confirm. BIGTREETECH PANDA PWR User Manual 10 NOTE: Please bring Panda PWR and Panda Touch closer together and complete the confirmation within 15 seconds, otherwise, it will prompt a binding timeout, and the PWR light will turn red. At this point, re-binding is required. 3.5. Unbind Panda PWR from Panda Touch If you wish to bind another printer, you must first unbind the current connection. BIGTREETECH PANDA PWR User Manual 11 3.6. Enable Automatic Power-Off Function When you need the printer to shut down after printing, activate the automatic power-off switch, configure the countdown time and temperature limit values, and start the countdown when the conditions are met. After the countdown is completed, Panda PWR will automatically cut off the power supply to the printer. 3.7. Clearing Electricity Consumption Panda PWR records the power consumption of the load. Press "RST Usage" to clear the power consumption data. 3.8. USB1 Follows the Printer Light When set to ON, USB1 will follow the changes in the printer's LED. If the LED is on, USB1 will output 5V voltage; otherwise, the output will be turned off. Additionally, USB1 supports manual setting for on and off. When set to OFF, USB1 only supports manual control. BIGTREETECH PANDA PWR User Manual 12 3.9. Indicator Light Description Blue: Unbound status Blue Breath: Binding in progress Red: Binding timeout Green: Normal communication Green Flashing: Communication error 4. Precautions 1. The communication between Panda PWR and Panda Touch uses a short- range method, which may be affected by obstructions. Please ensure there are no obstructions around the Panda PWR. 2. When connecting to a 220VAC input, first connect the input wires on the Panda PWR before connecting the wires to the socket. 3. The TYPE-C port can only be used for input. 4. The USB-A port can only be used for output. 5. FCC WARNING This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
