RN-52 Breakout
SparkFun Wish List
6. Status LEDs
There are two status LEDs located on the breakout board. However, if you
wish to place the board in an enclosure, these lines are broken out for
external LEDs. The LEDs are configured as open drain output, meaning
that they must be driven HIGH to activate the the LED.

Flashing
The module is connected.
Note:
Flashing refers to the LEDs flashing alternatively. If you see the
LEDs flashing in unison, then you are in DFU mode. Please check pin 3 if
you have entered DFU mode by accident.
7. SPI
External audio codecs can be sent over the SPI lines.
8. PCM
Another option for communicating with the module is the Pulse-Code
Modulation (PCM) pins. PCM is a way to digitally represent sampled analog
signals. This is done over an I S connection. External audio codecs can be
sent over these lines as well.
Hardware Setup
Before you can configure the module, some hardware needs to be
connected. This section will cover the necessary hardware needed to work
