CY8CKIT-042-BLE 蓝牙低功耗Pioneer开发套件
The CY8CKIT-042-BLE Bluetooth Low Energy (BLE) Pioneer Kit is intended for use as a development platform for hardware or software in a laboratory environment. The board is an open system design, which does not include a shielded enclosure. For this reason, the board may cause interference with other electrical or electronic devices in close proximity. In a domestic environment, this product may cause radio interference. In such cases, the user may be required to take adequate preventive measures. Also, this board should not be used near any medical equipment or RF devices.
The CY8CKIT-042-BLE Bluetooth Low Energy (BLE) Pioneer Kit is intended for use as a development, demonstration and evaluation platform for hardware or software in a laboratory environment. The kit is not intended for general consumer use. It generates, uses and can radiate radio frequency energy. It has not been tested for compliance with the limits applicable under any standard. Operation of the equipment may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. Cypress recommends that the kit only be used in a shielded room.
Thank you for your interest in the CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit. This kit is designed to showcase the functionality and ease of use of PSoC® 4 BLE and PRoC™ BLE devices while developing Bluetooth Low Energy (Bluetooth Smart) applications. Cypress’s BLE solution provides an easy-to-use, intuitive GUI to configure the BLE protocol stack using a BLE component available in the Cypress standard integrated development environment (IDE), PSoC Creator.
The CySmart PC tool allows emulation of a central device and quick access to peripheral connections and debugging. The solution provides a true single-chip solution with an integrated balun, Cypress’s industry-leading capacitive sensing technology, an analog front end (AFE) for biometric sensors, and digital peripherals suited to a wide variety of applications. Designed for flexibility, this kit offers footprint compatibility with several third-party Arduino™ shields. The kit includes a provision to populate an extra header to support Digilent® Pmod™ peripheral modules. In addition, the board features a CapSense® slider, an RGB LED, a push-button switch, an integrated USB programmer, a program and debug header, an F-RAM, and USB-UART/I2C bridges.
