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 5 m away, two independent BLDC motor controllers providing quiet, fast and precise control for gimbal motors, a CSI interface with two cameras on a flexible cable, two accelerometers, a gyroscope, and a temperature sensor.

SaraKIT is a versatile and powerful solution for those who want to build modern and efficient voice-controlled products, robots, home automation, and interact with smart home or office devices.
