ICM-42688-P-Module is a module of 6-axis acceleration/gyro sensor "ICM-42688-P" made by TDK.
- 4" x 5" (10.16 mm x 12.70 mm) PCB layout
- 2 x 5-pin + 1-pin 0.1" spaced PTH
- VDD : Power supply voltage
- VDDIO : IO power supply voltage
- SCL / SCLK : I2C serial clock / AP SPI serial clock
- SDA / SDI : I2C serial data / SPI serial data input (4-wire mode)
- AD0 / SDO : I2C slave address LSB / SPI serial data output (4-wire mode)
- CS : SPI Chip select (Connect to VDDIO if using I2C interface)
- INT1 / INT : Interrupt 1 / All interrupts mapped to pin 4
- INT2 / FSYNC / CLKIN : Interrupt 2 / Frame sync input / External clock input
- GND : Common Ground
- NC : Non Connection
- Input Voltage Range: 1.71V to 3.6V
- Digital-output X-, Y-, and Z-axis angular rate sensors (gyroscopes) with programmable full-scale range of ±15.625, ±31.25,±62.5, ±125, ±250, ±500, ±1000, and ±2000 degrees/sec
- Digital-output X-, Y-, and Z-axis accelerometer with programmable full-scale range of ±2g, ±4g ±8g and ±16g
- The host interface can be configured to support I3CSM slave, I2C slave, or SPI slave modes. The I3CSM interface supports speeds up to 12.5MHz (data rates up to 12.5Mbps in SDR mode, 25Mbps in DDR mode), the I2C interface supports speeds up to 1 MHz, and the SPI interface supports speeds up to 24 MHz.
- Digital-output temperature sensor

The following Arduino Library https://github.com/finani/ICM42688 was used to verify the operation.
The Arduino Board used is "Arduino Due".
Up to 3.6V is the supply voltage for VDD and VDDIO of this module.
- SPI : https://github.com/finani/ICM42688/tree/master/examples/Basic_SPI Wiring with Arudino Due is done as follows.
- I2C : https://github.com/finani/ICM42688/blob/master/examples/Basic_I2C/Basic_I2C.ino 4.7 kOhm resistors should be used as pullups on SDA and SCL, these resistors should pullup with a 3.3V source.
