CYBT-243053-02, EZ-BT Module
General Description
The CYBT-243053-02 is a dual-mode Bluetooth BR/EDR and Low Energy wireless module solution. The CYBT-243053-02 includes
an onboard crystal oscillator, passive components, and the Cypress CYW20820 silicon device.
The CYBT-243053-02 supports a number of peripheral functions (ADC, PWM), as well as multiple serial communication protocols
(UART, SPI, I2C, I2S/PCM). The CYBT-243053-02 includes a royalty-free stack compatible with Bluetooth 5.0 in a 12.0 × 16.61 ×
1.70 mm module form-factor.
The CYBT-243053-02 includes 256 KB of on-chip flash memory and is designed for standalone operation. The CYBT-243053-02 uses
an integrated power amplifier to achieve Class I or Class II output power capability.
The CYBT-243053-02 includes an integrated PCB trace antenna, is qualified by Bluetooth SIG, and includes regulatory certification
approval for FCC, ISED, MIC, and CE.
