定昌小编认为工控环境的核心板B2B板对板的连接器是比较牢固的，发热功耗低，不用风扇散热也能保持低温运行，防呆设计也做得比较好，不会接错，pin脚高密度小间距仅0.5mm，由160pin引脚提供全部核心板硬件资源。维修更换连接器的成本也低，适合工控设备同时对成本以及维护方面均有要求的客户首选。
其它功能介绍如下所示：
定昌全新DC_C133全志4核A133的1.6ghz核心板，由B2B板对板接口提供核心板资源连接，接口牢固，抗振动性能强，尺寸小巧，PCBA尺寸仅：50*30*4.8mm，6层PCB设计做工，提供最高2GB LPDDR4，32GB EMMC内存储存硬件资源，已适配安卓10系统，已大批量量产，欢迎测样。
