The CYBLE-212019-SHIELD is a Bluetooth low energy (BLE) host shield expansion board for the CY8CKIT-042-BLE development kit. This shield designed for Bluetooth 4.2 enables developers to quickly add a Bluetooth connection to existing projects or design their own Bluetooth connected device. Many applications are possible with this shield, ranging from data transceiving through Bluetooth or using it as a beacon device.

The CYBLE-212019-SHIELD consists of two major components, the main board and the antenna board. The main board provides all the necessary hardware for establishing a Bluetooth link including the BLE chipset, a 32-bit ARM Cortex-M4 host processor, 64KB of flash memory, and 8KB of SRAM. It also includes a USB connector, which can be used for programming and communication. The onboard battery and power supply regulator allow the board to operate on a single 3.3V battery, or an external 3.3V power supply. A large prototyping area is included for adding additional components or circuitry.

The antenna board is a high-gain, antenna booster PCB optimized for the CYBLE-212019-SHIELD. This board provides additional transmit/receive gain of up to 6dB from a small form factor SMT antenna. The antenna board includes a u.FL connector and it can be configured to operate over a variety of bands including the 2.4GHz ISM band.

CYBLE-212019-SHIELD applications include, but are not limited to, data transceiving, beacons, sensors, proximity detection, and so on. For data transceiving ,a host (a computer or a mobile device) and a peripheral (the CYBLE-212019-SHIELD) are necessary. Firstly, the host establishes a connection using the BLE protocol. Once the connection is established, data can be sent over the connection. On the peripheral side, the CYBLE-212019-SHIELD processes the data and stores it. This data can then be used to trigger certain actions, such as actuating a motor, turning on an LED, or triggering an alert.

Beacons, on the other hand, are typically used to detect proximity. An emitting device (the CYBLE-212019-SHIELD) sends out a special signal over a certain frequency. When a device is in close proximity to the signal, it triggers an action. This can be useful for navigation, indoor positioning, and so on.

Other applications include using the CYBLE-212019-SHIELD to detect motion, temperature, humidity, and other environmental factors. This board can be used to detect these parameters with high precision due to its onboard sensors and the large prototyping area.

The working principle of the CYBLE-212019-SHIELD is quite simple. It uses the BLE protocol to send and receive data via the antenna board. On the peripheral side, the board is equipped with all the necessary components required for operating a BLE module, such as the ARM Cortex-M4 processor, flash memory, and SRAM. It also includes a USB connector for programming and communication. On the receiving side, the board is responsible for processing the incoming data and storing it. This data can then be used to trigger certain actions.

In conclusion, the CYBLE-212019-SHIELD is an excellent expansion board for the CY8CKIT-042-BLE development kit. It is equipped with all the necessary hardware for establishing a Bluetooth connection and contains a large prototyping area for adding additional circuitry. The board’s applications range from data transceiving to beacon detection and environmental sensing. Its working principle is quite simple, using the BLE protocol to send and receive data. This board increases the possibilities for developers and enables them to quickly add a Bluetooth connection to their projects.
