{"product_id":"tk101-pdm-microphone","title":"TinkerBlock PDM Microphone Module, MEMS (TK101)","description":"\u003cp\u003eA tiny MEMS microphone block with a PDM digital output. It needs only two signal wires, a clock in and a data line out, so it records sound on any board with a PDM or I2S input. For voice capture, sound level meters and clap switches.\u003c\/p\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital microphone.\u003c\/strong\u003e No amplifier or ADC needed: CLK in, DATA out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo signal wires.\u003c\/strong\u003e Plus 3V3 and GND on a 4-pin right-angle header.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFiltered supply.\u003c\/strong\u003e A ferrite bead and capacitors clean the microphone's power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel jumper.\u003c\/strong\u003e A solder jumper selects left or right on a shared line.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrick-compatible.\u003c\/strong\u003e Two round holes fit standard building bricks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × PDM Microphone block (TK101), 4-pin right-angle header fitted\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCables and microcontroller are not included.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrophone:\u003c\/strong\u003e LMD2718T261-OA1 MEMS, PDM output\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply:\u003c\/strong\u003e 3.3 V, never 5 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e -26 dBFS at 94 dB SPL (datasheet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSNR:\u003c\/strong\u003e 58 dB(A) (datasheet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePins:\u003c\/strong\u003e GND, 3V3, CLK, DATA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWorks with\u003c\/h3\u003e\n\u003cp\u003eESP32, Raspberry Pi Pico and other 3.3 V boards with a PDM input.
