#Sense HAT

The Sense HAT is an add-on board for Raspberry Pi comprising of a 8×8 RGB LED matrix, a five-button joystick and the following sensors:

Gyroscope, Accelerometer, Magnetometer, Temperature, Barometric pressure and Humidity.

The shift register driving the LED Matrix is a LED2472G connected via an ATTINY88 to the SPI bus of the Pi. The Multi-Directional SKRHABE010 Switch/Joystick is similarly connected to the SPI bus.

The sensors themselves operate (mostly) over the i2c bus:

The IMU (Gyroscope, Accelerometer, Magnetometer) through a LSM9DS1 found at i2c address 0x1c(0x1e),0x6a(0x6b), with Interrupts on the ATTINY88.

Environemental sensors are represented by a LPS25H Pressure+Temperature sensor at address 0x5c and by a HTS221 Humidity+Temp sensor at 0x5f on the i2c bus.
