What is it?

This main control board is the master of the Grove Zero series of electronic modules, like the human brain which is the core controller of our actions and thoughts. You can use a connection cable or bluetooth to write programs to the bluetooth enabled main board. The main board receives data from input modules, processes logic and sends instructions to the output modules and communicates with other bluetooth devices. For example in a environmental noise alarm application, the main board receives data from the sound sensor (input module) and passes a judgement on whether the sound levels are above the maximum tolerated threshold and flashes an LED light (output module).

How this module works?

The Main Board BLE has a pre-loaded ‘snap-and-play Program’ to help you play and learn all the modules quickly and easily. Plug a 5v micro usb cable into the main board and it will also provide 5 volts of electricity to the other grove zero modules in the circuit (except for the motor). The micro USB cable is also used for uploading code and updating firmware.

Bluetooth Low Energy(BLE)allows you to upload your code or control your projects wirelessly.

You can program the Main Board BLE very easily with Codecraft to achieve more creative and challenging projects.
