Description
The Multiport Scale is an ESP32-based industrial weighing controller designed for automation, laboratories, R&D setups, machine integration, and serial/network-connected weighing systems.
It uses the same scale firmware base as the other hardware models, with product-specific interface options such as TTL UART, USB bridge, RS232, RS485, relay outputs, Bluetooth, and Wi-Fi.
Hardware Highlights
- ESP32 controller with Wi-Fi and Bluetooth capability
- 24-bit high-resolution ADC for stable load cell measurement
- 6-digit 7-segment display support using TM1637-style or custom display driver hardware
- TTL UART at 3.3V logic
- USB, RS232, or RS485 interface options depending on board assembly
- Relay outputs for fine/coarse or custom control use
- 5V supply or 7.4V Li-ion battery option with charger support
- Industrial-style board format for panel and enclosure integration
Firmware Features
- Weight, liter, piece counting, and auto scale modes
- Multi-level accuracy, and protocol setup
- Continuous, stable, stable-zero, key-triggered, or disabled data protocol
- Embedded web configuration
- BLE mode & Classic Bluetooth SPP mode
- mDNS device-name access for web and socket discovery
- Embedded web configuration page served
- mDNS device-name access in Wi-Fi mode
- TCP/UDP tranport and server / client socket modes
- Auto reconnect
- Thermal Printer Support
- Low-battery standby with automatic recovery when battery becomes healthy
Communication Use
- Use TCP server when PLC, PC, or billing software connects to the scale.
- Use TCP client when the scale must connect to a fixed server IP.
- Use UDP server/client when the connected system expects packet-based data.
- Use printer mode when Bluetooth or socket input must be passed to the serial printer/output port.
- Use RS485 or RS232 hardware variants when long-distance or industrial serial wiring is required.
Applications
- Industrial weighing and process control
- Batching, filling, fine/coarse control, and automation panels
- Laboratory testing and precision load measurement
- R&D projects with custom embedded interfaces
- Serial, RS485, USB, or Ethernet/Wi-Fi gateway-based integrations
- PC, PLC, billing software, and cloud gateway scale connections
