• Manufacturer: WIZnet

Specifications of EVB-B1+

• Rohs: yes
• Product: Evaluation Boards
• Interface Type: RS-232, SPI
• Operating Supply Voltage: 3.3 V, 5 V
• Data Bus Width: 8 bit
• Dimensions: 50 mm x 40 mm
• Processor Series: ATmega128

MOSI, /SS and SCK respectively.
② Active CPU Reset Select : JP11
Make CPU_RESET and /RESET go short using header shunt as shown in the picture.
When pressing the SW3(RESET SWITCH), active low signal is supplied to PM-A1
③ SPI Enable : JP18
For interfacing W3150A
case that SPI mode is not used, the pin of 2 and 3 should be shorted. The pin 2 of JP18 should be
connected to pin 33, SPI_EN signal of W3150A
④ Power Consumption Checking Point : JP15, JP16, JP17
To measure power consumption of EVB B/D, there is checking point for each power supply. The
soldered part should be removed and measurement is performed by Current Meter.
