3.2.1

CY8CMOD-062S3-4343W (MOD1)

CY8CMOD-062S3-4343W is a castellated PCB module which consists mainly of PSoC 6 MCU and
CYW4343W devices. The module also houses a 2.45GHz/5GHz dual band chip antenna, RF switch
for antenna diversity, Low Power Oscillator (LPO) for CYW4343W and PSoC 6 MCU, modulation
capacitor to support CapSense and other passive components required for the proper working of
PSoC 6 MCU and CYW4343W. A Pre-certified Type 1DX module with CYW4343W from Murata,
LBEE5KL1DX, is used for ease of development. CYW4343W supports only 2.45GHz band, but the
antenna used is 2450AD14A5500 Dual Band 2.45GHz/5GHz Mini Chip Antenna from Johanson, to
use the same antenna across different designs. The castellated PCB module has 137 castellated
pads, which are used for different voltage rails and I/O signals of PSoC 6 MCU and CYW4343W.
