S T E VA L - I D I 0 0 3 V 2 Multi-sensor RF platform sensor board Data brief Description The STEVAL-IDI003V2 is an evaluation platform for testing multiple MEMS sensors from STMicroelectronics. It is used in conjunction with the STEVAL-IDI002V2, as a daughterboard for the evaluation of the multi-sensor RF platform based on 6LowPAN. The STEVAL-IDI003V2 includes a MEMS accelerometer, pressure sensor, humidity sensor, and microphone. It also includes a photodiode. It connects to the STEVAL-IDI002V2 interface board using a 10-pin connector. Features Contains the following ST sensors: Pressure sensor LPS25HB Humidity sensor HTS221 Accelerometer LIS3DH Microphone MP34DT01 AFE for processing the MP34DT01 microphone signal based on TSV522 low power, low offset op-amp Android app available RoHS compliant May 2016 DocID028225 Rev 2 1/6 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagrams STEVAL-IDI003V2 1 Schematic diagrams Figure 1: STEVAL-IDI003V2 circuit schematic (1 of 5) 3V3 C1C1 1uF1uF 08050805 U1U1 3V3 1 13 VDD IO ADC3 110000nnFF 00440022 2 12 C2C2 NC GND R4R4 GPIO0 PA3 3 11 NC INT 1 LLIISS33DDHH 00 00440022 I2C2 SCL PB10 4 10 SCL/SPC RE SERVED 5 9 GND INT 2 I2C2 SDA PB11 R5R5 3V3 44kk77 04020402 R6R6 44kk77 04020402 ACCELERTOMETER SECTION GSPG11102015DI1050 Figure 2: STEVAL-IDI003V2 circuit schematic (2 of 5) GSPG11102015DI1055 2/6 DocID028225 Rev 2 6 SDA/SDI 16 ADC1 7 SA0/SDO 15 ADC2 8 CS 14 VDD
