SaraKIT for Raspberry Pi CM4

SaraKIT is a Raspberry Pi CM4 expansion board that enables advanced voice control and precise motor control. It features three sensitive microphones with sound localization for voice recognition up to 5m away, two independent BLDC motor controllers providing quiet, fast and precise control for gimbal motors, CSI interface with two cameras on a flexible cable, two accelerometers, a gyroscope, and a temperature sensor. In short, SaraKIT is a versatile solution for those who want to build modern and efficient voice-controlled products, robots, home automation, and interact with smart home or office devices.

SaraKIT Mainboard

SaraKIT with thre microphones and ZL38063 enables to analyse sound direction location. ZL38063 beamformer reports the angle of the most significant sound source for linear/triangular microphone configuration. The axis between Mics 1 and 2 defines the main axis, with 0 degrees to the right and +180 degrees to the left, with +90 degrees defined as being at the top of the array (opposite side of main axis from Mic 3)
