QuinLED-An-Mini Specifications

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:

Features

Based on the Espressif ESP32-C3 Micro-controller chip
- 2.4Ghz WiFi connection with External Antenna
- USB-C plug with programming capability
  - USB-C ESD protection chip
  - No lock-down, you buy it, you own it!
2x positive output channels
- Internally fused at 5Amp per channel with auto-reset fuses
5x analog 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)
Pluggable screw terminals
- All screw terminals are 5.08mm pluggable or 3.81mm pluggable style “rising clamp” terminals
- All with + (Philips head) screws
  - 1x 2p 5.08mm power input terminal (supports up to 10Amps)
  - 1x 2p 5.08mm positive power output terminal (fused at 5A per slot)
  - 1x 2p 5.08mm LED PWM output terminal (rated at 5A max each)
  - 1x 3p 3.81mm LED PWM output terminal (rated at 3A max each)
  - 1x 5p 3.81mm Button input
- 1x Stemma QT/Qwiic terminal for I2C devices
12v-48v Compatible with 10A max
- Please see dedicated Power Handling article for exact details!
High Quality modern MOSFET packages
- Including 5v MOSFET drivers (only on 2x high power output) and resistors to create smooth PWM in conjunction with the custom capacitor design circuit
Freewheeling (Flyback) Diodes
- To prevent back feed from blowing up the MOSFETs
Housed in a nice and small strong aluminium housing with clear labeling

Capabilities

High Speed PWM capable
- Recommended PWM speed 19531Hz with 13-bit Resolution (8192 steps)
  - 1kHz-4.9kHz with 14-Bit resolution (16384 steps)
  - 5kHz-9.9kHz with 13-Bit resolution (8192 steps)
  - 10kHz-19.9kHz with 12-Bit resolution (4096 steps)
  - 20kHz-39.9kHz with 11-Bit resolution (2048 steps)
  - 40kHz-79.9kHz with 10-Bit resolution (1024 steps)
  - 80kHz-159.9kHz with 9-Bit resolution (512 steps)
- Higher PWM frequencies possible with lowered bit depth (and potentially lower max power handling, please see power handling article for details)
Tuned MOSFET circuit
- Low level dimming capable
  - Depending on resolution available the QuinLED-An-Mini can dim LED strips exceptionally low through a highly tuned MOSFET circuit (recommended to use the 2x medium-power channels for best results)
- “Slowed down” PWM pulse to be more EMI compliant
  - Designed to support up to 120kHz PWM!
Power Supply friendly
- Fully custom DC-DC stage for internal power conversion (board electronics only)
  - Includes multiple built-in protection circuits
- Custom capacitor circuit layout with multiple capacitors per positive output channel to prevent current spiking for the power supply (and over the power wires) as much as possible
- “Low noise” PWM dimming
  - Design is fully optimized to prevent any “PWM noise” coming from the controller or power supply as much as possible!
High Voltage capable
- The QuinLED-An-Mini is built around being fully 48v compatible. This means new generation of LED strips can be used with less voltage drop issues over distance can be used!
Great WiFi coverage
- Using an external antenna, although small, WiFi reception is much better then with an integrated antenna!
Expandability
- No hardware lock-downs (you buy it, you own it!)
- Multiple button input, 3v3 and GND terminals
  - Button inputs with HW debounce circuit
  - Rotary encoder possible using 3x input!
- Stemma QT/Qwiic connector allows easy expansion with I2C devices such as temperature sensors, etc.
100% Native Home Assistant compatible
- Built around hardware that is natively compatible in ESPhome and WLED!
