Hardware Rework Guide for MIMXRT1170-EVKB and Murata

2EL M.2 Adapter

This section is a brief hardware rework guidance of the EdgeFast Bluetooth PAL on the NXP i.MX MIMXRT1170-EVKB and the Murata 2EL M.2 solution - direct M.2 connection to Embedded Artists’ Rev-A1 (2EL) M.2 modules.

The hardware rework has three parts:

• HCI UART rework

• PCM interface rework

• LE Audio Synchronization interface rework (only used on sink side)

Hardware rework

• HCI UART rework

  1. Remove resistors R183 and R1816.

  2. Solder 0 ohm resistor to R404, R1901, and R1902.

     

     

• PCM interface rework

  1. Disconnect header J79 and J80.

  2. Connect header J81 and J82.

  3. Remove resistors R1985, R1986, R1987, R1988, R1992, R1993, R1994, and R1995.

  4. Solder 0 ohm resistor to R228, R229, R232, R234, and R1903.

     

     

• LE Audio Synchronization interface rework (only used on sink side)

  1. Connect J25-15 with J97.

  2. Connect J25-13 with 2EL’s GPIO_27
