Description
DFRobot BLE4.1 Module is a Bluetooth 4.1 module with a DA14681 processor with a 3.3 V power supply. It is characterized by low energy consumption. The module integrates an advanced energy management system, supplied with the Li-on battery charging circuit with a maximum current of 400mA. It can be powered directly from the USB port. The module offers numerous I / O ports and communication interfaces: SPI, I2C, UART as well as PWM signal generation. The processor can communicate directly via the USB port (USB1.1 standard). In addition, the module offers the possibility of handling up to 4 connections at the same time, thanks to which it can be combined with other modules in a star or tree network. It is easy to use thanks to the Arduino library support. The module will be a comprehensive solution for IoT devices, devices requiring low power consumption or a network of distributed sensors. It can be used, for example, in the cooperation of several mobile robots.
