Prototyping Area

The provides blocks for connecting the address and data lines, GPIO ports, 3.3VDC and ground. It also provides an area (located under the LCD display board) for adding prototype circuits and components.

The components used to configure the on-chip op-amps are accessible in the op-amp configuration block. R29 adjusts the gain of the LNA. The regulated 3V3 and A3V3 voltages are independently adjustable via R7 and R49.

Note

• All microcontroller signals are brought out to pins and are driven directly by the microcontroller. Exercise caution to avoid overloading these signal lines.
