Open Source SCPI Programmable Precision Resistor Meter

A programmable resistor is an electronic device whose resistance can be adjusted, usually through a digital signal. Programmable resistors come in the form of integrated circuits (often called digital potentiometers) as well as stand-alone devices/expansion cards. There are many different applications, each with its own set of requirements.

​Range 1Ω - 999.999KΩ.

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.
