Circuit board manufacturer of radio frequency importer control board solution
Vibration motor: 3.7V 65mA.
Semiconductor refrigeration chip: TES1-7102, 23*23*3.5mm, component pair 71 pairs, 3.3-3.5Ω, Imax=2A; red wire positive electrode, black wire negative electrode, literally cold surface; 1.25mm terminal is used for wire end, no need Install plastic head.
Battery (provided by customer): 3.7V soft polymer battery.
Power off state: power off does not work. Press the power button to turn on.
Power-on state: when the power is turned on, the buzzer will beep for a long time (0.5 seconds), and then enter the mode used before the power-off. After pressing the power button, the buzzer will beep twice and shut down. The display shows the current mode, gear, current, remaining working time and dynamic effect when working
Gear shift: Click the gear up button to add one gear, and click the gear down button to decrease one gear.
Mode selection: Use the mode key to cycle through the import mode, export mode, radio frequency red light mode, ice compress blue light mode, and pull mode.
Import mode: display IMPORT, work time 5 minutes. Import function work, vibration motor work.
Export mode: display EXPORT, work time 5 minutes. The export function works, and the vibration motor works.
Radio frequency red light mode: display RF LED, working time 6 minutes. RF function work, red light function work, vibration motor gap work.
Ice blue light mode: display COOL LED, working time 3 minutes. Cooling plate work, blue light function work, vibration motor gap work.
Lifting mode: display SMOOTHING, work time 5 minutes. The EMS lifting function works and the vibration motor works.
Charging indicator: plug in the charger, enter the charging state, and all functions are turned off. The display only shows the battery level and gradually changes from the current level to the full level. When full, the battery indicator lights up continuously.
Low voltage shutdown: the battery power is 0, and the battery voltage is less than 3.2V, the buzzer drops twice and shuts down.
Shutdown at the end of time: After the working time of the current mode ends, the buzzer will be turned off twice.
