Processor & Core Components

  • CPU: Texas Instruments Sitara AM335x (ARM Cortex A8, 1GHz), supporting Linux/Android OS for complex dispensing logic.
  • Storage: 32GB eMMC (MLC) for OS and recipe storage; 4GB DDR3 SDRAM (1600MHz) for multi-tasking.
  • Open-Source Base: Hardware compatibility with Beaglebone Black/WH, enabling software reuse and community-driven development.

Connectivity & Interfaces

  • Wireless Modules:
    • WiFi: TI CC3100/CC3200 module (802.11 b/g/n), supports cloud connectivity for remote monitoring.
    • Bluetooth 2.1: TI CC2564 module, enables mobile app pairing for recipe adjustment.
  • USB Interfaces: OTG/Host USB 2.0 for peripheral connection (touchscreen, barcode scanner).
  • RTC: DS3231 precision clock with battery backup for time-stamped dispensing records.

Component & Packaging Details

  • Component Complexity: 143 unique components, including:
    • 0201 passive components: High-density resistors/capacitors for space optimization.
    • QFP/QFN ICs: Signal conditioning chips, motor drivers (e.g., TI DRV8840).
    • BGA packages: Cortex A8 processor (0.65mm pitch), DDR3 memory (0.8mm pitch).
  • Conformal Coating: 25-50μm polyurethane coating for moisture resistance (IP54 equivalent), critical for food-grade environments.
