STB2_1x1 is a board for testing purposes, used in combination with the self-tests for motherboards in the HAPS-50 series. With STB2_1x1 it’s possible to detect open circuits as well as power and ground faults in any HapsTrak II connector.

STB2_1x1 comes with dedicated designs to be downloaded into the FPGAs, and is included in the delivery of mother-boards. The board can be used for testing both the top and bottom side connectors.

For previous generations of HAPS motherboards the board STB1_1x1 should be used.
