Designed with [KiCAD](https://www.kicad.org/). This controller has version V0.1, which means it is still under development. **The source files can be changed.**\n\n![SimpleBLDC PCB in real life](https://raw.githubusercontent.com/techn0man1ac/SimpleBLDC/refs/heads/main/PCB/IMGs/Real_BLDC_Face.jpg)\n\nSimple BLDC 3-Phase BLDC motor driver specs:\n- Battery: 8S \n- VCC: 24.0V to 33.6V\n- I(max): 20A \n- Сurrent measurements per phase\n\n![SimpleBLDC PCB in real life_back](https://raw.githubusercontent.com/techn0man1ac/SimpleBLDC/refs/heads/main/PCB/IMGs/Real_BLDC_back.jpg)\n\nThe device has the following features:\n- XT60 power connector;\n- Arduino Nano V3.0 main controller;\n- Overcurrent protection (fuse);\n- Reverse polarity protection;\n- The ability to work with non-collector motors via Hall sensors (electric scooter or electric bicycle);\n- Monitoring and control of the current of each phase (current is measured in both positive and negative directions);\n- Current control by PWM, operating frequency 16/32 kHz;\n- Has a connector for connecting a traction control potentiometer and a reverse button.\n- Publication of the project under the [MIT license](https://github.com/techn0man1ac/SimpleBLDC/blob/main/LICENSE).\n\n# Schematic\n\n![BLDC motor driver schematic](https://raw.githubusercontent.com/techn0man1ac/SimpleBLDC/refs/heads/main/PCB/IMGs/Schematic.jpg)\n\nThe device has 3 drivers for mosfet transistors, as well as 3 current sensors based on the Hall effect, which measure both in the positive and negative directions. The use of 3 sensors is the reason for the development of the device for regenerative braking.\n\n# PCB\n\nThe board consists of two layers: top and bottom. All the main parts are located on the top layer.\n\n![Face PCB side](https://raw.githubusercontent.com/techn0man1ac/SimpleBLDC/refs/heads/main/PCB/IMGs/PCB_face.png)\n\nThe bottom layer contains mainly earth and power tracks.\n\n![The PCB bottom laye](https://raw.githubusercontent.com/techn0man1ac/SimpleBLDC/refs/heads/main/PCB/IMGs/PCB_back.png)\n\nBoard sizes is 72 x 99 mm:\n\n![BLDC motor driver schematic](https://raw.githubusercontent.com/techn0man1ac/SimpleBLDC/refs/heads/main/PCB/IMGs/PCB_sizes.png)\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftechn0man1ac%2Fsimplebldc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftechn0man1ac%2Fsimplebldc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftechn0man1ac%2Fsimplebldc/lists"}
