Alright, I need to rephrase the given text where each word is replaced with three alternatives in spintax format z, without touching proper nouns. Let me start by breaking down the text into individual words and phrases.
Looking at the original text, there are terms like "LED indicators for power, USB, and GPIO activity". Wait, there's a list here with three items: power, USB, and GPIO activity. But how does that fit into the v1 format? Maybe the user wants each of those items separated in a swapped manner. Wait, the instruction is to swap all terms with three options. Hmm, perhaps I need to look for any three-item lists and convert them into the v3 format, replacing the original list. Let me see.
Peripherals: The board has several peripherals, including: LED indicators for power A reset button for restarting the board A BOOTSEL button for selecting the boot mode
Let me start with the first sentence. "The YD-RP2040 schematic diagram is a crucial document that provides a detailed overview of the board’s components, connections, and interfaces." Breaking it down: "The" can be replaced with "A|This|That"; "schematic" with "diagram|layout|structure"; "crucial" with "important|vital|key"; and so on. Each word gets three options unless it's a proper noun.
"example projects" → sampledemosprojects.
Here, "documentation" in the proper noun part is part of the name, so left as is. In the sentence, "Official documentation..." → replace with references.
