Evaluation boardUART · SPIPDG IMUsA small adapter board that brings the signals of an Epson PDG IMU to pin headers, so you can wire the sensor straight into your own microcontroller or FPGA board.Epson lists it as the board for building the IMU into a customer system. You choose UART or SPI through the wiring, supply 3.3 V and start developing your driver on the real hardware.UARTor SPI, set by wiring3.3Vexternal supply6compatible PDG IMUsPinheader to your boardApplicationsWhere the M-G32EV031 fits bestEmbedded driver developmentBring up UART or SPI on your MCU, FPGA or single-board computer.Prototypes of robots and dronesMount the IMU in an early prototype before your own PCB exists.Gimbal and antenna controlTest the control loop with the real sensor and output rate.Test benchesIntegrate the sensor into measurement and validation setups.PerformanceKey dataParameterTypical valueTypeCustomer-board adapter for PDG IMUsCompatible IMUs (Epson)M-G370PDT, M-G370PDS, M-G370PDG, M-G370PDF, M-G366PDG, M-G330PDGSensor interfaceUART or SPI, selected by wiringConnectionPin headers to your boardSupply3.3 V from your systemNot includedIMU, jumper wires, power supplySoftwareEpson Sensing System Software, open-source drivers (C, ROS, Python)Typical values from the Epson data sheet.

Take the M-G32EV041 when you want to look at data on a Windows PC over USB first, without writing code.Which pins and voltages apply?The board runs at 3.3 V like the PDG IMUs. Pin assignment and electrical limits are in the Epson board and IMU data sheets, which we send on request.Which software do I need?Epson provides the Epson Sensing System Software free of charge after registration. It shows the sensor data as graphs and logs it to a file. For your own code, the open-source drivers for Linux, ROS/ROS 2, Python, MATLAB and Arduino are listed in our downloads.Is the sensor included?No. The evaluation boards connect a sensor you already have or order separately. We are happy to put together a matching set of board and sensor.Can I borrow a kit instead of buying it?Yes. For qualified projects we lend evaluation kits free of charge, so you can test in your own system before you decide.Test it in your own system.For qualified projects we lend evaluation kits free of charge.

Relay boardAccelerometer · VibrationM-A352M-A342The relay board takes an Epson M-A352AD accelerometer or M-A342VD vibration sensor and connects it to the USB board M-G32EV041 or directly to your own microcontroller board.Together with the M-G32EV041 it keeps the USB cable away from the sensor, so cable movement has less effect on vibration measurements. A second 20-pin connector lets you tap the sensor signals for your own electronics.2sensor families20pinsensor connector3.3Vsupply−20 … +70°Coperating rangeApplicationsWhere the relay board fits bestStructural monitoringRecord vibration and tilt with the M-A352 before you design your node.Machine conditionTest the M-A342 velocity and RMS output on a real machine.Tilt measurementEvaluate inclination resolution and stability on site.Own microcontrollerDrive the sensor from your MCU board via the breakout connector.PerformanceKey dataParameterTypical valueTypeRelay board for Epson accelerometers and vibration sensorsCompatible sensors (Epson)M-A352AD accelerometer, M-A342VD vibration sensorConnectorsCN1 20-pin to sensor, CN2 9-pin to USB board, CN3 20-pin breakout (Hirose DF20)Supply3.3 V, from the M-G32EV041 or your own boardOperating temperature−20 … +70 °CPC connectionvia USB board M-G32EV041 (sold separately)Not includedSensor, USB board, harness M-G32EV051Typical values from the Epson data sheet.
