- 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.
- 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 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.
