This 30cm-long cable has a male JST-PH 4-pin connector on one end and 4 male DuPont connectors on the other.

Note: this cable can be used with older models of HyperPixel 4.0 which have a JST connector underneath for connecting I2C devices. Newer versions of HyperPixel 4.0 (from June 2019) have a standard female DuPont header and can be used with jumper jerky.
