SaraKIT is a Raspberry Pi CM4 expansion board designed to offer advanced voice control and precise motor control capabilities. It is equipped with three highly sensitive microphones that support sound localization, enabling voice recognition at a range of up to 5 meters. In addition, SaraKIT also integrates two independent BLDC motor controllers to provide silent, high-speed, and precise control of gimbal motors. This expansion board also features a CSI interface with two cameras, two accelerometers, a gyroscope, and a temperature sensor connected via a flexible cable.

SaraKIT is a versatile and robust solution suitable for individuals looking to create modern and efficient products with voice control capabilities, as well as for those interested in building robots, home automation systems, and interacting with smart home or office devices.
