PCB interface assembly instructions for Bluesound Node 2/2i

Assembly

Remove the rear cover by pulling it at the indicated places.
Remove top two indicated screws.
Lift the upper part of the housing by tilting it only from the back of the device, until you hear loud "clicks". Then lift it upwards, being careful not to break the tapes and cables.
Put the upper case carefully next to it. Do not disconnect cables, the sockets are secured with adhesive.
Disconnect the small and large socket. You can use longer pliers for this.
Remove screws indicated by the arrows.
Remove screws on the back panel.
After removing factory power supply and stiffening plate, look to the retaining pin. Insert the new interface so that the pin indicated goes into the retaining hole in the module.
Screw the module on, also please install the stiffening plate as shown in the picture.
Connect the large JST connector to the socket on the motherboard. Twist the cable harness slightly, being careful not to pull them out of the plug.
Mount the back panel - screw the black screw into the indicated hole.
Close the housing by first hooking the indicated latches. If you can't do it, use a little force.
Screw the black screws back into place.
Install the rear panel cover.
After installation should remain: the factory power supply and two silver screws. If the components differ, check the correct assembly.

Additional information

Measurement and regulation

The power supply required by the module should be between 5 and 5.1V. The module has voltage measuring points - described: VCC and GND. They are used to measure voltage under load. They can facilitate fine adjustment of the power supply (if the power supply has such a possibility).

Socket polarization:

Specifications

• Supply voltage: 5V DC
• Power supply current: min 2A
• Built-in 3A fuse
• Short-circuit and overload protection: ≥ 6V
• Reverse polarity protection
• LEDs indicating module operation (upper: control voltage, lower: main voltage)

The "U2" part is a fuse. It is part of the security features and is a replaceable part (spare part attached to the manual). Blowing the fuse is deliberate to protect the device and its replacement is not covered by the warranty. It may act due to incorrect power supply voltage or connection.

If necessary, a replacement with the following parameters can be used:

• Type of operation: fast-acting fuse
• Housing SMD - 1206
• Voltage 32V, maximum allowed 63V
• Fuse current 3A
• Maximum allowed resistance: 30 mOhm (0.03 Ohm)
• Maximum allowed voltage drop: 90 mV (0.09 V) at 3A current
