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.

Example of use, demonstration of the speed and power of BLDC motors

This movie showcases one of the applications of SaraKIT, an extension kit for Raspberry Pi 4 in CM4 version.

The SaraKIT kit includes most of the necessary elements:

- Two FOC gimbal motor drivers for BLDC motors
- An accelerometer with a gyroscope
- Support for motor encoders
- 3 sensitive microphones for voice control
- Two camera outputs for live streaming from a moving vehicle
- The ability to connect power from easily available Power Banks (PD2.0 PD3.0 Fast Charging and QC4 with USB-C output) with a special PD 12v cable or by connecting a USB cable via USB-C Pd Trigger Module Pd 12v.

Additionally, you will need two BLDC gimbal motors, two encoders, two motor-to-brick adapters, and some building blocks. The design of the vehicle is up to you. The brick adapters can be easily 3D-printed (the relevant stl and obj files are included on our website) or purchased for a few dollars from our site.

This robot demonstrates the power of BLDC gimbal motors; it is very difficult to overturn, quiet, and fast, and does not require heavy loads to be placed high up.
