Description Three-axis analog signal output 1. Onboard MMA7361 (replaces MMA7260) low-cost miniature capacitive acceleration sensor; 2. Support 5V/3.3V voltage input, onboard high-speed LDO, lower voltage drop, faster load response speed, very suitable for high noise power supply environment; 3. The range is selected through the IO of the single-chip microcomputer, and the resistance can also be selected; 4. Commonly used pins have been led out, and the pins are standard 100mil (2.54mm), which is convenient for dot matrix board; 5. Sleep enable can be controlled by MCU IO; 6. Volume (length, width and height) 27.9mm*16.8mm*11mm  7. The center distance of the needle rows on both sides: 24.852mm;
