AnyPCBA PCB and PCBA case studies
Our client, a manufacturer of smart travel products, needed a wireless control system for their electric luggage product line. Unlike the wired controller+dashboard approach used in their previous model, this version required complete remote control capability. The system needed reliable wireless communication, intuitive handheld operation, and robust motor control – all in a compact, user-friendly package.
Key System Components:
Motor Controller: 36V 10A±1, based on Zhongying MCU, with onboard receiver
Remote Control: Handheld unit with joystick, gear switch, power button, pairing key, and charging port
Receiver: Integrated on the main controller board (CH MCU)
Control Interfaces: Motor phase output, Hall sensor, ON/OFF line, power supply
Product Highlights:
Wireless Control: Full remote operation via handheld remote control
36V 10A System: Higher current capacity for more powerful motors
Three-Speed Operation: Forward 1 (0-5km/h), Forward 2 (0-10km/h), Reverse (0-3km/h)
Flexible Pairing: Two methods for easy user setup
Intelligent Power Management: Auto-shutdown for extended battery life
1. Wireless Remote Control System
The handheld remote control features intuitive operation with a joystick, gear switch, power button, and dedicated pairing key. It includes a charging port and battery holder for convenient power management.
2. Dual Pairing Methods
| Method | Operation |
|---|---|
| Method 1 | Press pairing key on remote → Remote LED flashes → Power on controller → Auto-pair within 30s |
| Method 2 | Power on controller → Press pairing key on remote → Remote LED flashes → Press pairing key on controller → Pairing completed |
3. Three-Speed Control
| Mode | Speed | Application |
|---|---|---|
| Forward 1 | 0-5km/h | Slow cruising, maneuverability |
| Forward 2 | 0-10km/h | Normal riding, higher speed |
| Reverse | 0-3km/h | Backing up, parking |
4. Intelligent Power Management
Remote auto-shutdown: 35s if not connected; 60s if connected but inactive
Power-on/off with audible buzzer confirmation
Low-voltage protection at 31V (±0.5V)
Over-current protection at 10A (±1A)
5. Fault Diagnosis via LED Indicator
| LED Flash Pattern | Fault Type |
|---|---|
| 4 flashes | MOSFET over-current protection |
| 5 flashes | Hall sensor fault |
| 6 flashes | Motor lock protection |
| 7 flashes | Under-voltage protection |
| 8 flashes | Over-voltage protection |
| 9 flashes | Over-temperature protection |
| Parameter | Specification |
|---|---|
| Battery Voltage | 36V |
| Maximum Current | 10A ±1A |
| Motor Type | 3.5-inch, right cable output |
| Controller MCU | Zhongying |
| Receiver MCU | Qinheng (CH) |
| Remote Control MCU | Qinheng (CH) |
| Sleep Current (Controller) | Less than 20uA |
| Standby Current (Controller) | Less than 100mA |
| Minimum Start Voltage | 12.5V |
| Low-Voltage Protection | 31V ±0.5V |
| Forward 1 Speed (no-load) | 0-5km/h |
| Forward 2 Speed (no-load) | 0-10km/h |
| Reverse Speed (no-load) | 0-3km/h |
| No-Load Current | Less than 1A |
| Thermal Protection | Motor stops at 110°C |
| Remote Auto-Shutdown | 35s (disconnected) / 60s (idle, connected) |
| Pairing Timeout | 30 seconds |
