2.2 Breakaway Module (BM)
The Breakaway Module (BM) contains a MBN52832 module preconfigured with an onboard 2.4GHz
antenna, two LEDs, 32 KHz sleep clock and a NFC antenna. There is also an u.FL connector for RF
evaluation and header pads to access the I/O pins of the module. BM can be separated from the IM and
used as a standalone carrier board of MBN52832 for product prototyping.

2.2.1 32KHz clock
The 32KHz clock is connected to P0.00 and P0.01 on the module. If this clock is not needed, then resisters
R43 and R44 may be installed and R45 and R46 removed to free these pins for application usage.
