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

With three sensitive microphones, it is possible to recognize speech from a distance of up to 5 meters, which makes it easy to integrate the device with Amazon Alexa, ChatGPT, Google Home, and other voice control systems.

In the version with the pan-tilt camera, facial detection and tracking allow for activation with just a glance (without the need to speak wake words like "Alexa" or "OK Google"). An example of this can be seen in the demonstration video:
