Iotiny LED Blinking Issue

I have an IoTiny that begins with a fast, continuous blue blinking LED and does not display the initial aqua blue color. Additionally, there is no startup sound, and the reset button seems unresponsive. The power supply has been verified as stable, and I also connected another IoTiny with the same power supply, which functioned normally. Therefore,...

DSSERVO 3225 Servo Compatibility Inquiry

Hi @Athena, I am curious about the compatibility of a 25 kg DSSERVO 3225 digital servo, which operates at 4.8 to 6.8 volts DC, with my EZBv4. Additionally, I'm considering placing a 10F capacitor between the positive and negative wires. Would this assist or interfere with the servo's operation when using the EZBv4? Thank you, Jack
