6. SMD Jumpers
Jumpers J0, J1 and J2 connect MCP2120
controller BAUD0, BAUD1 and BAUD2 pins
to VCC or GND. You can change baud rate
settings by soldering J0, J1 and J2 in the
appropriate position (Table 1). These jumpers
are soldered in logic 1 position by default
(9600 bps, software selection enabled). SMD
jumper J3 is used to select 5V or 3.3V power
supply (default position is 3.3V).
