CYW94343WWCD1_EVB Evaluation Kit

The Infineon CYW94343WWCD1_EVB kit includes a CYW94343WWCD1 SIP module mounted on a full-featured USB-based evaluation and development board. The onboard SIP module leverages the CYW4343W, featuring an 802.11b/g/n Wi-Fi MAC/baseband/radio and Bluetooth 4.2. In addition, the module integrates a power amplifier (PA) that meets the output power requirements of most handheld systems, a low-noise amplifier (LNA) for best-in-class receiver sensitivity, and an internal transmit/receive (iTR) RF switch, reducing the overall solution cost and printed circuit board area. The CYW94343WWCD1_EVB also includes an on-board STM32F411 32-bit Arm microcontroller.
