This high-voltage buck converter is specifically designed for e-scooter and e-bike control power supply applications, but its versatility also makes it suitable for use in solar energy systems, automotive systems, and industrial power supplies. This converter utilizes the MPS9486...

A buck converter board has been developed utilizing the BD9G341AEFJ, a non-synchronous DC/DC converter. This board accepts a wide input voltage range of 12V to 76V DC and generates a regulated 5V DC output. The BD9G341AEFJ features an integrated 150mΩ N-channel MOSFET and a...

The project presented here features an 8-channel digital and 2-channel analog isolator. The board is equipped with 6 forward digital isolators and 2 reverse digital isolators, in addition to 2 analog isolators. The digital isolators boast an impressive 5000 VRMS isolation rating,...

This 48V, 200mA dimmable linear LED driver is a highly reliable solution for various LED applications. The project features the BCR602 chip, which supports LED engines, LED modules, and LED strips. The driver utilizes a MOSFET (Q1) and the BCR602 chip to provide constant current...

The project presented here is a high-current adjustable PWM (Pulse Width Modulation) source, designed to drive various loads such as PTC (Positive Temperature Coefficient) devices, DC motors, solenoids, high-power LEDs, and valves. The project consists of three main components: an...

Do you know how to use external (hardware) and timer interrupts in microPython?. There is a way of guaranteeing that some code will be executed upon an external event (button press, etc) or a time passing. In today's post, we will explore how the external and timer interrupts work....

This article implements a laser distance sensor with OLED display and RP2040, using the VL53L0x laser distance sensor. We will use a really small 0.49-inch OLED display that communicates with RP2040 via I2C. By distance, I mean we will be able to measure how far in millimeters an...
