The SPH0645 breakout module is specifically designed for use with Raspberry Pi (all common models), as well as Cortex-M series microcontrollers like the Feather M0 and Arduino Zero. Simply ensure your board has an I2S interface and operates at 3.3V logic.\u003c\/p\u003e\n\u003ch4\u003eQ: Can I use two of these modules together for stereo audio recording?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. To capture stereo audio, purchase two SPH0645 modules. Share the clock, WS, and data lines between them, then configure one as the left channel and one as the right channel using the Select pin. This gives you a true stereo digital audio input.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this module work with 5V Arduino boards?\u003c\/h4\u003e\n\u003cp\u003eA: No — the SPH0645 has a maximum operating voltage of 3.6V and is not compatible with 5V logic systems. It is best suited to 3.3V boards with native I2S support. Standard 5V Arduino boards typically lack I2S support anyway, so this module is best paired with 3.3V I2S-capable platforms.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is the SPH0645 I2S MEMS microphone module compatible with Raspberry Pi?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes!
