Figure 22. SX1230 Reference Design
The SX1230 reference design in shown above with connections for MCU mode operation. The values of all band
independent components are shown, for the appropriate RF matching please see Section 7.6. The corresponding 2-layer
PCB layout is shown in Figure 23. The example design size for the radio portion of the design (not including push button or
stand alone mode functionality) is encompassed by the green box whose largest dimensions are 19 x 10 mm.
