Hurricane turbine handheld fan, dual cooling, extremely fast cooling, 8m/s ultra-wide-angle hurricane, 100 gears to adjust at will
Cold wind & ice compress dual cooling, superconducting ice magnetic refrigeration device is added to the air outlet. While the icy cool wind is sweeping out, the ice magnetic refrigeration ball will cool down rapidly, which can be attached to the skin to achieve a double strong ice experience
0.5s extremely fast cooling: using aerodynamic principles, built-in high-speed turbine rotation, bringing strong cold wind
Built-in AI protection chip, overvoltage protection/high temperature protection/short circuit protection/overcurrent protection/overcharge protection/over-discharge protection
LED digital display, control the gear and power at any time
Very small and light, it does not take up space when carried outdoors
DFPlayer Mini MP3 module, can be directly connected to speakers
Module with power supply battery, speakers, buttons can be used alone, can also be controlled through the serial port, as a module for Arduino UNO or any microcontroller with a serial port
The module itself integrates MP3, WAV, WMA hard decoding, while the software supports TF card driver, FAT16, FAT32 file system
Through a simple serial port command can be completed to play the specified music, and how to play music and other functions, without the need for cumbersome underlying operations, easy to use, stable and reliable

Accurate value, with ACV ACA true RMS measurement
Overload protection to ensure user safety
Backlight design, clear reading without effort
Can be tilted/hung, convenient for measurement and reading, test lead storage slot design
The upgraded open design of the outer filter cover does not require tedious steps to disassemble other accessories of the hair dryer. Just remove the old filter and follow the instructions to easily replace it. This open design can also facilitate daily cleaning and can be easily disassembled and replaced anytime.
The outer filter cover is suitable for Dyson hair dryers HD01 HD03 HD08, and HD15 models.
30 mesh filter cover, powerfully intercepting various dust impurities
The dust filter can effectively isolate dust and protect the internal parts of the hair dryer from damage. It is recommended to replace the dust filter regularly for better machine performance.
There are MOS and other components on the board, which are easily damaged by soldering iron induction electricity or static electricity. Please make sure that the soldering iron used is grounded (and the ground wire of the power strip is connected). It is best to wear anti-static gloves when operating.
Be careful not to install the battery upside down, otherwise the board may burn.
Please choose a power supply with sufficient power. Only in this way can the board work properly.
The board power supply should not be higher than 5V.
Please do not modify the board without technical confirmation.
It is normal for the module to heat up when working at high power, just pay attention to fanning.
