This is a 3 Axis Low-g Micro machined Accelerometer module from Rhydolabz with sensitivity selection using MMA7260QT accelerometer Sensor from Freescale. This Module is Suitable for Robotic application and other Tilt Measurements. Board Form factor is very small for robotic design and is easily fixable. MMA7260QT BOARD FEATURES Compact and Ready to use Professional EMI/RFI Complaint PCB Layout Design for Noise Reduction On board MMA7260QT Accelerometer Sensor Two Jumpers for selecting sensitivity (±1.5g/±3g/±4.5g/±6g) Power supply ranges from 5V to 10V On board 3.3V regulator Separate On board pins for analog voltage out for each tilt angles (X,Y,Z) On Board input pin for Sleep mode On board power indication led On board Power Supply De coupling Capacitor Three On Board RC filter for minimizing clock noise of each angle Easy to interface Host Controller Two centrally arranged Screw Holes for Correct mounting Low Cost
MMA7260QT CHIP FEATURES Low cost capacitive micro-machined accelerometer A 1-pole low pass filter Temperature compensation G-Select which allows for the selection among 4 sensitivities. Zero-g offset full scale span and filter cut-off (factory set) Require no external devices. Includes a Sleep Mode that makes it ideal for handheld battery powered electronics. Selectable Sensitivity (1.5g/2g/4g/6g) Low Current Consumption: 500 µa Sleep Mode: 3 µa Low Voltage Operation: 2.2 V to 3.6 V 6mm x 6mm x 1.45mm QFN High Sensitivity (800 mv/g @1.5 g) Fast Turn on Time High Sensitivity (1.5 g) Integral Signal Conditioning with Low Pass Filter Robust Design, High Shocks Survivability Pb-Free Terminations Environmentally Preferred Package
