Cypress Semiconductor Class II Change Letter Date: 2019-09-23 To whom it may concern, Request for Class II Permissive Change Product Name: EZ-BT WICED Module with Mesh FCC ID: WAP3034 Model No.: CYBT-413034-02, CYBT-413055-02, CYBT-413061-02 Modification: 1. Add model CYBT-413055-02 and CYBT-413061-02. 2. The difference between CYBT-413034-02, CYBT-413055-02 and CYBT-413061-02 is the main IC. Module RF IC RAM Size Flash Size Package Supported （KB） （MB） Bluetooth Standard CYBT-413034-02 CYW20719B1 512 1 QFN40 BR/EDR/BLE CYBT-413055-02 CYW20719B2 512 1 QFN40 BR/EDR/BLE CYBT-413061-02 CYW20721B2 512 1 QFN40 BR/EDR/BLE 3. The difference of main ICs is: CYW20721B2 is identical to CYW20719B2 but for different marketing applications. CYW20721B2 is more intended for use in audio application while CYW20719B2 is for IOT general applications. Compared to CYW20719B1, CYW20719B2 and CYW20721B2 has the same RF parts but upgrades the firmware, just to improve PMU and memory performance. The new operation mode (BT5.0 2Mbps) is enabled by firmware upgrades. 4. The same conditions of the main ICs are: CYW20721B2 component is pin-for-pin compatible. CYW20721B2 has the same basic function as CYW20719B2. 1/2

Cypress Semiconductor No change in radio parameters has occurred. The same conditions apply when a small area (approximately the same area as the chip) of the PCB is replaced with an equivalent chip. Yedan Li / System Engineer Cypress Semiconductor 2/2
