BLE Shield
The BLE (Dual Model) part of Seeed Studio BLE Shield is an integrated Bluetooth Low Energy (BLE) chip and dual-mode Bluetooth 4.0 that allows connection and transfer of data from other BLE-enabled devices. It provides communication between devices over short distances and enables low-power, resource-constrained devices to be connected with SPDT relays and external sensors. The shield offers various interfaces such as PWM, I2C, SPI, UART, and analog inputs for controlling, monitoring and recording data from different devices. Its integrated characteristics enable it to be used in applications such as the Internet of Things (IoT), home and industrial automation, and many more. It also features a 4-layer PCB, optimized design, and secured data encryption in order to ensure a reliable connection and data transmission.
