Speeduino Open Source ECU: Arduino-based engine management

The Speeduino project is a flexible, fully-featured engine management system (EMS aka ECU) based on the low-cost open-source Arduino platform. It provides the hardware, firmware, and software components that make up an engine management system, all under an open license. With over 1,000 installations, Speeduino has evolved into a product that meets the needs of the hobbyist and enthusiast community without the price tag of a traditional aftermarket ECU.

60W Brushless DC (BLDC) Automotive Motor Driver Design BOM, PCB Files and Gerber Files

The reference design is a BLDC motor controller designed to be powered by a single 12V (nominal voltage) supply with a wide voltage range found in typical automotive applications. The board is designed to drive motors in the 60W range, which requires a current of 5 amps. The size and layout of the board facilitates evaluation of the drive electronics and firmware, with easy access to key signals on various test points. A wide variety of motors can be connected by using a 3-contact connector or soldering the motor phase wires to the plated through holes in the board. The 12VDC supply is fused to prevent damage to the board or bench power supply in the event of a motor failure during testing. Commands and the status of the motor can be transmitted through a standard JTAG connector or through PWM input and output signals. The user can also reprogram the microcontroller through the JTAG connector, allowing customization for various applications. This design forms the solution by incorporating the DRV8301-HC-C2-KIT board.

Mornsun Electric Vehicle Power Supply Design Reference

The difference between electric vehicles and traditional fuel vehicles lies in the power part, which is also the core part of electric vehicles. Pure electric vehicle systems usually include three systems, namely the electric drive subsystem, the main energy subsystem and the auxiliary control subsystem. Among them, the electric drive subsystem consists of an electronic controller, a power converter, an electric motor, a mechanical transmission device and drive wheels; the main energy subsystem consists of a main power supply, an energy management system and a charging system; the auxiliary control subsystem has functions such as power steering, temperature control and auxiliary power supply.
