OnBoard VGA Enabled 4:3/1:1LCD Screen Machine Development Board

Unlike HDMI, which transmits digitalsignals directly from the CPU, VGA requires no licensing fees, offering significant cost advantages. Even singlechip microcontrollers can drive VGA,let alone Android development boards. Currently, many factories still use monitors with VGA interfaces in large quantities.   

Why Some Development Boards Still Adopt OnBoard VGA (Dingchang’s Analysis):   

1. Legacy Display Compatibility   

4:3 and 1:1 screens with VGA interfacesremain in market circulation. Some industries specifically require LCD screensin 4:3/1:1 aspect ratios for development, prompting Dingchang to retain VGA equippeddevelopment board models.  

2. Superior AntiInterference Capability   

As an analog signal, VGA outperforms HDMI in antiinterference. Additionally, VGA cabling can extend up to 30 meters, farexceeding 1:1 HDMI cables (815 meters) while costing less.  

3. Industrial Cabling Advantages   

For large machine chassis wiring, HDMI requires shielding, whereas VGA’s inherent antiinterference makes it simplerand more practical for deployment.  

4. Tendering Requirements in Government Projects   

Some government project specification sexplicitly mandate VGA to enhance bid control rates.
