AFE-R761 PCIE M.2 B KEY

HW Pin define：

 

 

SW Function：

SATA (model: IM2S3334 - 512GCTB4)

The M.2_B-KEY interface of the AFE-R761 supports two types of signals, and the specific type depends on the configuration you have purchased. One is the PCIE sig�nal, and the other is the SATA signal. To test the M.2_B-KEY SATA signal, can use the SATA disk (model: IM2S3334 - 512GCTB4).
