Carrier module

The baseboard design of the CYW920829B0M2P4XXI100-EVK board is a modular so that various carrier modules
can be used with the same baseboard. In this kit, the CYW920829B0M2P4XXI100 carrier M.2 radio card module,
which employs the CYW20829 device, is connected to the baseboard through M.2 interface. The carrier module
interface is a generic interface used across many devices. See
interface description. The Bluetooth® antenna is etched on the carrier module PCB. UART signals and GPIOs are
brought out from module pins to interface with the baseboard.

CYW20829 Module M.2 Board Details

The CYW920829B0M2P4XXI100-EVK board employs the CYW20829 device which is a 56-pin QFN package. This
board uses all 26 GPIOs provided by the 56-pin QFN package.
3.1.2

Antenna

A PCB antenna is etched on the carrier module. This antenna is matched to 50 Ω when the
CYW920829B0M2P4XXI100-EVK board is placed on a table.

Crystal

The CYW20829 carrier module has two crystals onboard. A 24-MHz crystal (XTAL) is the main crystal. This XTAL
must have an accuracy of +/-20 ppm as defined by the Bluetooth® specification. A 32.768-kHz crystal provides
accurate timing during low-power operation. See the
3.2

Base board

CYW9BTM2BASE3 is a baseboard on which the CYW20829 carrier module is connected. This baseboard provides
various sensors to interface with the CYW20829 device.
