Qiyangtech adopts present IAC-335X core board, develop QY-335X-MB baseboard, which totally conforms to the standard of State Grid, customers could directly use it to charging station billing unit control. Moreover, compared to SBC, customization cycle of core board+customed baseboard is shorter, and it will be more flexible in later designing and functional modifying.
EV mainboard Core Module is designed by 6-floor PCB; the volume is only card size; together with CPU, DDR2 RAM, NandFlash, DataFLash, network; using 5V dc power supply, low power consumption; 2 x 100 BtoB connectors lead various commonly used interfaces; The core module is compatible with all AM335x-ARM Cortex-A8 series processors, and the users can choose different types of appropriate processor chip to reduce cost(only for bulk users).
