We now look at the moustache logic board to see what chips make this MacBook a Pro:

Intel Core i5-6267U processor with Intel Iris Graphics 550

Intel JHL6540 Thunderbolt 3 controller

SanDisk SDRQKBDC4 064G 64 GB NAND flash memory (x2 for a total of 128 GB)

Samsung K4E6E304EB-EGCE DDR3 DRAM (4 x 2 GB for 8 GB total)

Texas Instruments SN650839 66AL7XWGI, and TI/Stellaris LM4FS1EH SMC Controller (Replacement codename for TM4EA231)

Murata/Apple 339S00056 Wi-Fi Module

Likely Apple SSD controller underneath (also likely) Micron R4432ACPE-GD-F 512 Mb memory, probably similar to this one.
