QuinLED An-Penta-Mini Capabilities

Back to QuinLED An-Penta-Mini Index

The QuinLED-An-Mini was designed with keeping cost and a small form factor in mind dictating it’s design and features. Please see a list of it’s hardware features and capabilities below.

Capabilities

PWM and bit depth resolution

For the An-Penta-Mini the PWM bit depth available is a little bit more complicated then for the bigger ESP32’s! In short, if you are using the Arduino IDF you are locked to using a 40Mhz clock source by default. Using the ESP-IDF you can however use the 80Mhz clock source giving you a higher bit depth available.

Big thnx to Paolo for figuring all this out!

What this boils down to is the following:

  • ESPhome    (Which IDF is used can be configured!)
    • Arduino IDF – 40Mhz
    • ESP-IDF – 80Mhz
  • WLED
    • Arduino IDF – 40Mhz
      • For WLED to use a high bit depth then 8 Bit depth you require WLED v0.15-b3 or higher!

Recommended frequency for running the An-Penta-Mini (power figures have been determined for this PWM frequency) is 19.569Hz. With the 40Mhz crystal you will get a 11 Bit depth and with the 80Mhz crystal you will have a 12 Bit depth!

Bit Depth Capabilities depending on crystal frequency:
(a . denotes a thousand!)

  • 80Mhz
    • 1Hz-4.892Hz with 14-Bit resolution (16384 steps)
    • 1Hz-9.784Hz with 13-Bit resolution (8192 steps)
    • 1Hz-19.569Hz with 12-Bit resolution (4096 steps)
    • 1Hz-39.138Hz with 11-Bit resolution (2048 steps)
    • 1Hz-78.266Hz with 10-Bit resolution (1024 steps)
    • 2Hz-156.555kHz with 9-Bit resolution (512 steps)
      • Higher PWM frequencies are possible with lowered bit depth (and potentially lower max power handling, please see power handling article for details)
  • 40Mhz
    • 3Hz-2.446kHz with 14-Bit resolution (16384 steps)
    • 5Hz-4.892Hz with 13-Bit resolution (8192 steps)
    • 10Hz-9.784Hz with 12-Bit resolution (4096 steps)
    • 20Hz-19.569Hz with 11-Bit resolution (2048 steps)
    • 39Hz-39.138Hz with 10-Bit resolution (1024 steps)
    • 77Hz-78.277Hz with 9-Bit resolution (512 steps)
      • Higher PWM frequencies are possible with lowered bit depth (and potentially lower max power handling, please see power handling article for details)

Voltage capabilities

  • 12v-48v Compatible with 10A max
    • Internally fused at 5Amp per channel with swappable fuses
      • Please see dedicated Power Handling article for exact details!

Flexibility and Current capabilities

  • 5x analog PWM output channels
    • 2x “medium-power” channels up 5A  (generally for white LED strips)
    • 3x “low-power” channels up to 3A  (generally for RGB LED strips)
    • Because of programmability of the controller these can be used “as seen fit” such as:
      • 5x white individually controllable
      • 1x RGB + 2x white individually controllable
      • 1x RGB+CCT (so a strip with Red, Green, Blue, Warm White and Cold White LEDs)
