Instant purchase OK. Multiple available. Please comment if you'd like one. This is a module that makes the ADXL-335, a chip-type 3-axis accelerometer sensor, easy to use by soldering it onto a board. It has an analog voltage output, so you can measure acceleration as voltage. Specifications: ・Measurement Range: ±3g ・Sensitivity: 300mV/g (when powered by 3V) ・0 (zero) g output: 1.5V (when powered by 3V) ・Power Supply Voltage: DC3V (Operating Range: DC1.8V ~ DC3.6V) Please feel free to comment if you have any questions.
