IDC737-1 Qualcomm-Based aptX Bluetooth® Audio Module

IOT747's IDC737 is a fully integrated dual-mode Bluetooth, Bluetooth low energy (BLE) data, and audio module. The device is based on the Bluetooth 5.2 Qualcomm audio chip, features a long life, and is easy to supply at volumes. The small form factor is 11.8 mm x 18 mm and is Bluetooth, FCC, and CE-certified. The IDC737 is similar to the iDC747 with the addition of an external antenna.

The IDC737 offers a high-level UART command interface making it very easy to integrate into an existing product and provides full control of the profiles including SPP, AGHFP, HFP, A2DP (sink and source), AVRCP, and connects to Android and iOS apps using BLE (concurrent primary and secondary). The module can act as a receiver of music and a transmitter.

The IDC737 integrates Qualcomm SnapDragon sound (aptX, aptX-HD, and aptX-adaptive) for better audio performance with many devices. The user can configure the module to transmit the audio that is received via a high-quality integrated analog codec (100 dBA SNR) or directly to a digital interface. This module offers extremely low power consumption (<6 mA streaming music <0.1 mA connected or paired) with a range of up to 25 m.
