To reduce the size of the VBCore embedded module, a JST GH series programming and debugging connector with a 1.25 mm pitch is installed. Additionally, the programming pins are exposed on the module's contact pads.

For user convenience, we developed a custom miniature programmer board compatible with ST-Link V2.1 rev 1.1 and its interface connector. Our programmer also supports serial communication (Virtual Com Port) routed through the programming connector.

Additionally, a small adapter board is available for standard ST-Link programmers, but without VCP (Virtual Com Port) support.
