| Pin / wire | Position | Role | Notes |
|---|---|---|---|
| Vin | power in | this is the power pin. Since the sensor chip uses 3 VDC, we have included a voltage regulator on board that will take 3-5VDC and safely convert it down. | |
| 3Vo | power out | this is the 3.3V output from the voltage regulator, you can grab up to 100mA from this if you like | |
| GND | ground | common ground for power and logic I2C Logic Pins | |
| SCL | i2c scl | I2C clock pin, connect to your microcontroller's I2C clock line. This pin is level shifted, so you can use 3-5V logic, and there's a 10K pullup on this pin. | |
| SDA | i2c sda | I2C data pin, connect to your microcontroller's I2C data line. This pin is level shifted, so you can use 3-5V logic, and there's a 10K pullup on this pin. | |
| AD0 | address | I2C Address pin and jumper. Pulling this pin high or bridging the solder jumper on the back will change the I2C address from 0x68 to 0x69 SPI Logic pins: | |
| CS | spi cs | this is the Chip Select pin, drop it low to start an SPI transaction. Its an input to the chip If you want to connect multiple ICM20649's to one microcontroller, have them share the SDA, SDO and SCL pins. Then assign each one a unique CS pin. | |
| INT1 | interrupt | The first interrupt pin. You can setup the ICM20649 to pull this low when certain conditions are met such as a value exceeding a threshold. Consult the datasheet (https://adafru.it/JnC) for usage | |
| INT2 | interrupt | The second interrupt pin. You can setup the ICM20649 to pull this low when certain conditions are met such as a value exceeding a threshold. Consult the datasheet (https://adafru.it/JnC) for usage | |
| FSYNC_IN | other | Used to sync the sensor with an external source. Consult the datasheet (https://adafru.it/JnC) for usage. Connected to GND by default. Cut the jumper on the bottom of the breakout to use the external pin |
| Connector | Type |
|---|---|
| stemma_qt | STEMMA QT / Qwiic I2C (JST SH 4-pin), two connectors |
Ranges are the largest selectable full-scale setting; noise densities are typical datasheet values.
Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
