Board Dimensions
On board sensors
Configuration | VOXL (M0006) | VOXL Legacy aka Qualcomm Flight Pro (HA942) | Interface |
---|---|---|---|
IMU0 | ICM20948 | MPU9250 | SPI10 |
IMU1 (recommended) | ICM20948 | MPU9250 | SPI1 |
Barometer | Bosch BMP280 | Bosch BMP280 | i2c3 |
GNSS | Internal Snapdragon | Internal Snapdragon | TBD |
IMU Notes
Note: IMU1 consistently performs better than IMU0. IMU1 is strongly recommended for flight and VIO use. SNAV 1.3 and greater, which is found at developer.modalai.com, uses IMU1 by default.
Recommended Operating Conditions
- Operating Temperature: -10°C to +70°C
