PCA9685BS Frequently Asked Questions (FAQs)

  • The maximum frequency of the PWM output is 1526 Hz, but it can be adjusted using the PRESCALE register.
  • The PRESCALE value can be calculated using the formula: PRESCALE = 25000000 / (4096 * frequency) - 1, where frequency is the desired PWM frequency in Hz.
  • The minimum duty cycle is 0% (LED off) and the maximum duty cycle is 99.6% (LED almost fully on).
  • No, the PCA9685BS is designed to drive LEDs and other low-current loads. It's not suitable for driving inductive loads like relays or solenoids, which require more current and voltage protection.
  • The PCA9685BS can be reset by setting the SLEEP bit in the MODE1 register to 1, then setting the RESET bit in the MODE1 register to 1, and finally setting the SLEEP bit back to 0.
