The Arduino Leonardo is a microcontroller board based on the ATmega32U4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started (USB cable and power supply are not included). This board ships with the female header pins soldered in, as shown in the product picture.

- LSM303 Arduino library
- This is a library for the Arduino that interfaces with our LSM303D, LSM303DLHC, and LSM303DLM 3D compass and accelerometer carriers as well as the compass and accelerometer ICs on the MinIMU-9 v2 and AltIMU-10 (it also works with older versions of those boards, some of which used the LSM303DLH). It makes it simple to configure the device and read the raw accelerometer and magnetometer data, and it has a function for computing the tilt-compensated heading for those looking to use the LSM303 as a tilt-compensated compass.
- L3G4200D and L3GD20 Arduino library
- This is a library for the Arduino that interfaces with our L3G4200D and L3GD20 3-axis gyro carriers as well as the gyros on the MinIMU-9, MinIMU-9 v2, and AltIMU-10. It makes it simple to configure the device and read the raw gyro data.
- MinIMU-9 + Arduino AHRS
- This Arduino program (sketch) allows an Arduino connected to a MinIMU-9, MinIMU-9 v2, or AltIMU-10 to function as an attitude and heading reference system, calculating estimated roll, pitch, and yaw angles from sensor readings that can be visualized with a 3D test program on a PC. It is based on the work of Jordi Munoz, William Premerlani, Jose Julio, and Doug Weibel.
