ezBLDC is a two axis smart BLDC motor driver, powered by SimpleFOC. Implementing 2 DRV8313s this board is capable of 12V @ 2.5A / phase for control of up to 2 motors at once. With its onboard smarts, this board can accept simple UART, I2C, or step/dir commands to control complex, real-time, feedback-enabled motion, freeing up the main microcontroller to do other tasks. Implementing the hardware basics for controlling brushless DC motors can be a hassle, but it doesn't have to be. This motor driver allows anyone with an Arduino to get moving with BLDC motors, with easy IO and motor connectors onboard.

Three-Terminal Fixed Positive Voltage Regulator The LM7812T is a three-terminal fixed positive linear voltage regulator IC designed to provide a stable +12V DC output from a higher input voltage source. It belongs to the widely used 78xx series regulators, where “12” indicates the fixed output voltage of 12 volts. It is commonly used in power supply circuits, embedded systems, and electronic devices that require a simple, reliable regulated 12V rail without the complexity of external components. The device operates as a linear regulator, meaning it reduces voltage by dissipating excess energy as heat, so proper heatsinking is often required for higher current loads. Key Features of LM7812T Fixed +12V output voltage Output current up to 1A–1.5A (depending on package and cooling) Input voltage range up to ~35V max Built-in thermal shutdown protection Internal current limiting and short-circuit protection Safe-area compensation for reliable operation No external components required for basic operation Good line and load regulation Low quiescent current (~8 mA typical) Available in TO-220 / TO-3 packages (LM7812T variants) Typical Applications DC power supplies (12V regulated rail) Arduino and microcontroller systems Industrial control electronics Sensor and communication circuits Battery-powered systems requiring stable 12V Audio amplifiers and small motor control circuits #CommonPartsLibrary #IntegratedCircuit #PowerManagement
