 # Raspberry Pi Pico SDK Examples
 
 By default, the Pico SDK targets builds for RP2040 (PICO_PLATFORM=rp2040). To build for RP2350 instead, pass
-`-DPICO_PLATFORM=rp2350` to CMake (or `-DPICO_PLATFORM=rp2350-riscv` for RISC-V).
+`-DPICO_PLATFORM=rp2350` to CMake (or `-DPICO_PLATFORM=rp2350-riscv` for RISC-V). Alternatively, in many cases, you can rely
+on the board configuration to set the platform for you. For example, passing `-DPICO_BOARD=pico2` will automatically select RP2350.
 
 Most, but not all examples, currently work on RP2350 however you should be able to do a full build with any of the above platforms (PICO_PLATFORM=host however currently fails on some examples)
