EasyEDA开源硬件项目——Replacement PCB For OP-320A HMI which gives partial Arduino compatability 拥有Arduino 部分功能的OP-320A人机界面的替代PCB板子。 The PCB attaches to the back of the OP-320A unit (picture), which is a cheap operator console panel you can get off aliexpress or ebay for about $50, you remove the PCB with the unit and attach this, Wiring mostly copied from teensy++ and uno so something of a mix here, you will definitely need to adjust your sketches.Note in my system I did not use the back plastic cover as it was going into another panel and the original back cover wont we deep enough to accommodate the unit. I dont recommend making one yourself until I have tested it fully :-) Weighbridge HMI PLC 地秤人机接口界面可编程逻辑控制器 Weighbridge HMI PCB 地秤人机接口界面PCB EasyEDA: https://easyeda.com/ EasyEDA链接: https://easyeda.com/rodyne/Repla ... atability-jgM4mEyQ8 |
