    Buck converter calculation does not match with LTspice results

    Probably due to non-ideal parts đź‘Ť Check ESR, inductor DCR, diode/MOSFET drops, and CCM vs DCM.

    Max Current and Shorted Current

    Max current is what the device can safely supply under normal conditions, while short-circuit current is the much higher current that flows when the output is directly shorted (and usually only for a brief moment). Always design for protection, because short-circuit current can damage components...

    Arduino + A4988 Stepper Motor Driver Help

    Hi 🙂 Make sure wiring is correct — STEP & DIR to Arduino and common GND. Also set the current limit. Example: STEP → D3, DIR → D4 Send HIGH/LOW pulses on STEP to rotate motor. If it only vibrates, check coil wiring or use proper external power 👍

    Which MCU do you prefer — ESP32 / STM32 / RP2040 / Arduino?

    ESP32 for most projects (WiFi + Bluetooth), STM32 for performance, RP2040 for flexibility, Arduino for beginners đź‘Ť

    Looking for a remote job opportunity at Electronics Lab

    Hey! You might want to share a bit more about your skills (like PCB design, embedded systems, testing, etc.) and experience it’ll help the right people notice you. Also try checking remote roles on platforms like LinkedIn or Indeed. Good luck! 🙌

    Looking for OFF the shelf HDMI/FPGA MIPI DSI convertor with support

    Expect some configuration work, not a simple plug-and-play solution.

    Which MCU do you prefer — ESP32 / STM32 / RP2040 / Arduino?

    Depends on the project 🙂 For me, I’d go with something that has built-in connectivity and good performance it just makes things easier.
