1.0 DEVICE OVERVIEW
Roving Network’s RN52 Bluetooth audio module pro-
vides a highly integrated solution for delivering high-
quality stereo audio in a small form factor. It combines
a class 2 Bluetooth radio with an embedded DSP pro-
cessor. The module is programmed and controlled with
a simple ASCII command language.
The RN52 module complies with Bluetooth specifica-
tion version 3.0. It integrates RF, a baseband controller,
etc., making it a complete Bluetooth subsystem. The
RN52 supports a variety of profiles including HSP/HFP,
A2DP, AVRCP, SPP, and iAP. It provides a UART inter-
face, several user programmable I/O pins, stereo
speaker outputs, microphone inputs, and a USB port.
Table 1-1 provides the general specifications for the
module. Tab l e 1- 2 and Table 1-3 provide the module’s
weight, dimensions, and electrical characteristics.
Figure 1-1 shows the module’s dimensions and
Figure 1-2 shows recommended landing pattern and
