Summary

IDC747 is ideal for developers who want to quickly and cost effectively integrate high performance Audio and Data

Bluetooth functionality into their products. It is controlled through a simple UART or USB interface that also serves for

data transmissions. For the Audio, it has Analog or Digital Outputs. The module can connect to multiple devices with

multiple profiles. The power consumption is <1mAmp when connected, <1mAmp in Pairing mode and <6mAmp when

streaming music at 3.3V. It is supplied FCC, CE and Bluetooth 5.2 certified. It is also supplied with sample Android

and iOS Applications to help integrate the Bluetooth functionality with the product end Application. IDC747-1 features

can be also customised for specific complex use cases and scenarios. Please contact info@iot747.com for

customisation requests.

If power is present from the battery and/or charger, and software has placed the device in the Power OFF mode, a long button press (SYS_CTRL held high for 20 ms) boots the device. Once the module is booted, SYS_CTRL acts like a standard PIO.

This can be configured. If GPIO control is not used, these GPIOs should be left floating. The UART by default does not use RTS/CTS flow control. If the users do not expect to use it, these lines should be left floating.
