Up2Stream Mini is WiFi and Bluetooth audio receiver board that can be easily integrated to your existing audio hardware devices to enable
them with network and bluetooth streaming capability. With Up2Stream installed and using app 4STREAM, it allow you to stream music from
cloud, phone, NAS, and famous streaming services, such as spotify, deezer, qobuz, tidal..etc. It also support multiroom and multizone control
and music playback with multiple units connected .

B
PH2.0-7P:BT_LED,WIFI_LED,GPIO2,GPIO1,ADC_KEY,
GND,VCC_3V3 (top to bottom)
GPIO2 and GPIO1 is used to connect a coding key, should be
used for volume control. KEY is a ADC key port, reference the
diagram below for key definitions. BT_LED, WIFI_LED are used
to extend the LED, and are common-anode connected. You
should connect 3.3V to a current limit resister and then to LED
and then to the pin. (reference the diagram below)
C
PH2.0-7P: SPDIF, MCLK, IIS_DATA, BCLK, LRCK, GND,
VCC_3V3:
This is the digital audio output extension. For the IIS, BCLK is
2.8MHz, the LRCK is 44.1KHz, the MCLK is 11.288MHz, the
DOUT following the standard IIS data format and have 16 bits
depth. The system is running in master mode, you should make
sure the IIS port of connected device is running in slave mode.
J
PH2.0-4P: ROUT, GND, LOUT, GND
: For analog output to
amplifier board, it has same signal with the 3.5mm Aux jack.
