In addition, there is Ralemo word on the metal palm support.
The inside is provided with mouse parameter information, the model is AIR 1, and 5V450mA is input, and FCC, KC, and CE certification have been passed.
The bottom edge of the mouse is posted with a white polytetrafluoroethylene foot pad, and both ends are Bluetooth keys and wireless charging marks, and both sides are USB-C charging ports and power keys.
This mouse supports wired and wireless charging, sustainable for 25 days under charge; additional support for Bluetooth 5.0 and wireless 2.4G connections, connecting terminal devices such as computers, tablets, and mobile phones.
The mouse is intuitive experience in the hand.
The net weight is about 71g.
Use the scene list.
The mouse built-in LED lamp, turns off after the blue blister is stopped, as long as one use (including sliding) will flash, so the design has increased the cool feeling when using it, and it will not affect the rest when not in use.
Wireless charging for the mouse, the LED lamp flashes red.
The wireless charging input power is 8.98V 0.47A 4.26W at this time.
In addition, a wired charging test can be measured using KT002 to measure the charging power of 5.15 V 0.25A 1.28W.
Second, Leber Ralemo Air 1 wireless mouse disaster
Remove the bottom of the mouse bottom, the bottom housing is fixed using the screw.
Removing the screw is open, the outer casing also encapsulates the package.
The bottom housing can be removed by removing the screw, and the internal light guide plastic is fixed using a screw and a fixed column.
Two PCB board connection is designed inside the mouse, and the PCB board is fixed using screws.
The upper PCB plate has 5 LED indicators.
There is a battery under the PCB board and connected by a connector.
Between the two small plates are also connected by wire plug, and the wireless charging coil is bonded to the bottom plate.
Remove all the board, the battery, the roller, etc.
The front side of the small board is vertically welded to the USB-C input master, and the right side is the battery socket, the left side connecting the wire and the wireless charging coil, the center is a wireless charging receiving chip.
The other side is provided with 5 LED indicators for wireless connection mode tips.

The wireless charging receiving chip is in parallel with the three resonant capacitances above the Miyin MT5705. The MT5705 is a SOC (on-chip system) based on magnetic inductive wireless charging receiver. It features embedded ARM Cortex M0 processors, 2KB SRAM, 8KB OTP, fully compliant with the latest WPC QI specification for BPP (version 1.2.4).
The MT5705 provides stable 5W output power, supports output voltage 5V and current maximum 1A, AC TO DC conversion efficiency of 95%; its perfect overvoltage, overcurrent, over-temperature protection mechanism, independent I2C communication interface and rich GPIO. Encapsulate
4.00mm x 4.00mm QFN32L
, Especially suitable for TWS earphone charge bin and other small power intelligent equipment.
