MicroHAPS HT3x2-HT4x2 Adapter (SH100008643) — the Synopsys-provided "Generic HT3x2-HT4x2" adapter board that mounts on the microHAPS (KU5p tester) and bridges it to the DUT's HT4 connectors. Part of the HT3 test stack alongside microHAPS (ETT00000008) and Snowball (ETT00000010), used to test the B12-N HT3 Panel Board (ETT00000009).

• E-Sharp does test-development with this board; the board design is Synopsys (SNPS) — E-Sharp does not own/design it.
• Primary domain: test; secondary: electronics.
• Why it matters: the adapter defines the microHAPS ↔ DUT-HT4 pin/signal mapping (which FPGA IO drives each CONx_IO / CLK / I²C, and where the HT4-side 12 V and I²C originate) — the missing link needed to complete the B12-N production-test pin map (see B12-N test spec Open Items O-10/O-11).
• ⚠️ Schematic/ODB for SH100008643 not yet on hand — to be provided by Synopsys (HAPS hardware per the Phase-A SOW), then ingested into Probe.
• Naming: "x2" = 2 channels per adapter → ~3 adapters for the B12-N's 5 channels.
