Shenzhen Jiusheng Technology Co., Ltd. SE24065-Module Shenzhen Jiusheng Technology Co., Ltd. Tel：0755-33919819 SE24065-Module Application Description Shenzhen Jiusheng Technology Co., Ltd. SE24065-Module Shenzhen Jiusheng Technology Co., Ltd. Tel：0755-33919819 1. Module Overview This module is a highly integrated 433.92MHz wireless remote control PCBA, specifically designed for smart health and personal care devices. It integrates RF transmission, lithium battery charge management, LED driving, vibration motor driving, and a rich set of key input interfaces. Intuitive control is achieved through five multi-function buttons, with all operational statuses indicated via dedicated LED lights. Multi-function Control: Integrates EMS intensity adjustment, heating level switching, RGB LED color control, vibration control, and mode switching. Clear LED Indication: Uses dedicated LED lights to display battery power, EMS intensity level (0-20), current working mode, and heating status. User-friendly Interaction: Clear button multiplexing logic for intuitive operation. Low Power Design: Supports automatic sleep mode after 30 seconds of inactivity. Integrated Charging: Built-in charging management circuit for direct connection to a lithium battery. 2. Function and Button Description The module has 5 physical buttons with the following functions:  Power Button (PWR) Short Press (<1s): Turns the vibration motor function ON or OFF. Each short press toggles the vibration state. Long Press (>3s): Turns the module ON or OFF. Press and hold to power on from an off state; press and hold to power off from an on state.  Mode Button (MODE) Short Press (<1s): Cycles through the working modes. The module supports 6 preset modes (e.g., Mode 1 to 6). Each press switches to the next mode, and the corresponding dedicated "Mode Indicator LED" will illuminate. Long Press (>2s): Turns the heating function ON or OFF. The heating function is independent of the EMS mode and cycles through three levels (Low, Medium, High -> Off).  LED Button Short Press (<1s): Cycles through the RGB LED colors (e.g., Red, Green, Blue, Purple, Yellow, White, etc.). This function is typically used for ambient lighting or status indication.  Intensity Plus Button (+) Short Press (<1s): Increases the EMS output intensity level. The level increases from 0 to 20, remaining at 20 upon further presses. The two-digit display shows the current level.  Intensity Minus Button (-) Short Press (<1s): Decreases the EMS output intensity level. The level decreases from 20 to 0, remaining at 0 upon further presses. The two-digit display shows the current level. Shenzhen Jiusheng Technology Co., Ltd. SE24065-Module Shenzhen Jiusheng Technology Co., Ltd. Tel：0755-33919819 3. LED Indicator Description The module's status is indicated by the following LED groups: Battery Power Indicators:A series of LEDs (e.g., 5 LEDs) dynamically indicate the remaining power of the built-in lithium battery. Charging status is indicated by a specific pattern (e.g., scrolling). 6 Mode Indicator LEDs: Six dedicated LEDs correspond to the 6 different working modes. The LED for the currently active mode is lit. Two-digit 7-Segment Display: Displays the current EMS Intensity Level (0-20). 3 Heating Level Indicator LEDs: Indicate the heating status. 1 LED ON: Low-level heating. 2 LEDs ON: Medium-level heating. 3 LEDs ON: High-level heating. All OFF: Heating is off. 4.Workflow and Auto-Sleep Power On: Connect the battery or press and hold the PWR button for more than 3 seconds. The module boots up, and relevant status LEDs illuminate. Normal Operation: The user interacts via the function buttons. All statuses are updated via the corresponding LED indicators. Auto-Sleep: When the module has no button operation for 30 seconds, it will automatically turn off all LED indicators and enter a low-power sleep state. The RF, motor, and other peripheral circuits are shut down, maintaining only button detection. Wake from Sleep: In the sleep state, short pressing any button (except for the long-press power-off function) will immediately wake the module, restoring all LED indicators to the state before sleep.
