Functionality
2.1 Power
The shield requires a 3V3 supply to power the PCB. This is generated with an onboard 3V3 regulator
supplied with 5V supplied by the Vinco baseboard.
An additional 1V8 supply for the VS1053b audio codec is generated from an onboard regulator.
2.2 Input/Output
Connection to the Vinco baseboard is via pin headers. The Ethernet port, the audio CODEC and the Real
Time Clock are accessed by the VNC2 via SPI interface between the boards .
An RJ45 connector with inbuilt Speed and Link LEDs is provided for connecting to external Ethernet ports.
A 3.5mm audio socket is provided for connecting headphones to the audio CODEC output.
MIC input to the audio CODEC is available on header pins.
2.3 LEDs
There are 4 LEDs available on the shield.
1. LED1: Ethernet Full Duplex indicator is driven from the W5001 IC to indicate the Ethernet port is
in full duplex mode.
2. LED2: Ethernet Collision indicator is driven from the W5001 IC to indicate the Ethernet port is
experiencing data collisions.
3. LED3: Ethernet Received Data indicator is driven from the W5001 IC to indicate the Ethernet
port is receiving data.
4. LED4: Ethernet Transmitted Data indicator is driven from the W5001 IC to indicate the Ethernet
port is transmitting data.
2.4 Switches
SW1: A momentary switch to send a reset signal to the VNC2 controller on the Vinco baseboard.
