    Hi everyone, I’m using a JK flip-flop for a simple state control circuit. Pressing the push button should toggle once, but sometimes the output changes twice or returns to the previous state. The button has only a resistor and capacitor debounce network. Questions: Is the issue likely...

    UART Communication Becomes Unstable Near Motor Driver Section

    Hi all, I’m building a robotic platform where an STM32 communicates with another controller over UART. Communication is clean until the BLDC driver starts switching under load. Then I get framing errors and occasional packet loss. The UART traces pass near the gate driver area on a 2-layer...

When I turn on more than 10 LEDs at same time, sometimes ESP32...
