QuinLED An-Penta-Mini Specifications
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.
Features
Micro-Controller and Connectivity
- 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
- Expandability and no lock down!
- No hardware lock-downs (you buy it, you own it!)
- No problem installing updates to firmware
- Program whatever you want to it!
- Great WiFi coverage
- Using an external antenna, although small, WiFi reception is strong and allows for easier placement in your house or project location.
- Internal ESP32-C3 Temperature Sensor
Power and Dimming/PWM
- High Voltage capable
- The QuinLED An-Mini is 12v-48v compatible
- This enables new generation LED strips with less voltage drop issues over long distances!
- Please see the power handling article for more details surrounding that subject
- The QuinLED An-Mini is 12v-48v compatible
- 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!
- Fully custom DC-DC stage for internal power conversion (board electronics only)
- Built-in Fuses
- Internally fused positive output channels
- 2x replaceable fused positive output channels
- Onboard electronics have their own auto-reset fuses
- Internally fused positive output channels
- High Quality modern MOSFET packages
- Including 5v MOSFET drivers (only on 2x medium power outputs) and resistors to create smooth PWM in conjunction with the custom capacitor circuit
- Allows better dimming granularity, for the An-Penta-Mini this is related mostly to the 2x medium-power channels.
- Other boards in the An-Penta line-up use an even higher gate voltage allowing even more granular control over the LEDs, especially at lower levels.
- Allows better dimming granularity, for the An-Penta-Mini this is related mostly to the 2x medium-power channels.
- Tuned MOSFET circuit
- Decent Low level dimming capable
- Especially the 2x medium-power channels have a decent granularity available of dimming levels
- “Slowed down” PWM pulse to be more EMI compliant
- Designed to run ~20kHz PWM without a problem
- Freewheeling (Flyback) Diodes
- To prevent back feed from blowing up the MOSFETs
- Decent Low level dimming capable
- Including 5v MOSFET drivers (only on 2x medium power outputs) and resistors to create smooth PWM in conjunction with the custom capacitor circuit
Expandability
- Stemma QT/Qwiic connector allows easy expansion with I²C devices
- Hooks into existing eco system providing easy to buy and hook up sensors such as:
- Temperature sensors
- Humidity sensors
- Light sensors
- extra input pins, etc.
- Can also be used as 2x GPIO, 3v3 and GND connector for custom accessories
- Hooks into existing eco system providing easy to buy and hook up sensors such as:
- Multiple button input, 3v3 and GND terminals
- Button inputs with HW debounce circuit
- Rotary encoder possible using 3x input!
- Onboard QuinLED I²C temperature sensor socket
Housing
- Housed in a nice and small, strong aluminium housing with clear labeling
- Color coded terminals to easily identify plugs!
Software and integration
- 100% Native WLED and ESPhome compatible
- Built around hardware that is natively compatible in ESPhome and WLED
- Multiple ways to natively integrate board into Home Assistant
