SENSORS

POLPO 2This demonstration board is the first memberof the POLPO 2 module family, developed byFuture Electronics’ System Design Center (SDC).It combines a temperature sensor, a pressuresensor, a gyroscope, a magnetometer and anaccelerometer. These MEMS sensors will providea 3-axis sensing of linear, angular and magneticmotion, complemented with temperature andbarometric/altitude readings.This inertial demonstration board represents acomplete hardware platform which can be usedin numerous applications such as virtual reality,augmented reality, image stabilization, humanmachine interfaces and robotics.A complete set of communication interfaceswith various power supply options in a uniqueform factor make POLPO 2 a flexible and opendemonstration platform.To aid in user development, the demonstrationkit includes a complete source code library tofacilitate the use of the demonstration boardfeatures.KEY FEATURESn Three power supply options: USB connector,Batteries Boost or Batteriesn STM32L152VBT6: Ultra-Low-Power ARM Cortex-M3 basedMicrocontrollers, 128K flashn STTS75D: temperature sensor with –55 to +125°C range and I 2 Cdigital interfacen LPS331AP / LPS001WP: pressure sensor 300-1100 mbarabsolute full scale with I 2 C digital output and barometern L3GD20 / L3G4200D: ultra-stable 3-axis gyroscope fullscale of ±250/±500/±2000 dps, I 2 C digital outputn LSM303DLHC / LSM303DLH: 6-axis geomagnetic module: ±2 g /±4 g / ±8 g linear acceleration full scale, magnetic field configurablefull scale ±1.3 to ± 8.1 gauss (max), I 2 C digital outputSTTS75DDigital temperature sensor& thermal watchdogn Extended connector for communication and GPIOn USB 2.0 full speed connectionn Reset buttonn User LEDs and buttonsn LCD 8 Digits x 14 Segmentsn Touch PadsMini-USBTEMPERATUREST: STTS75DBUTTONSPRESSUREST: LPS001WPLPS331AP/LPS001WPMEMS pressure sensorPOWER MANAGEMENTUSB or BATTERIESST: L6920ST: LDS3985M33RST: LDS3985M18RSEGMENT LCDMICROCONTROLLERST: STM32L152VBT6LEDsGYROSCOPEST: L3G4200DL3GD20/L3G4200DLow-power three-axisangular rate sensorTOUCHPADSEXPANSIONACCELEROMETERMAGNETOMETERST: LSM303DLHLSM303DLHC/LSM303DLH6-axis module:Accelerometer andmagnetometerTo qualify for a FREE demo board,go go to www.FutureElectronics.com/STMicroto
