Dig-Next-2
Specifications
As the initial overview pay already mentioned the Dig-Next-2 is geared towards entry level to medium size LED setups. Depending on voltage this ranges from a few meters up to 30m! The specifications are carefully selected with the combined experience of thousands of LED installs over the years, adapting the hardware to what users need most, in my opinion, to build an easy to install and safe LED setup.
Hardware specifications
- ESP32 based
- Dual-Core 240Mhz microcontroller
- 8MB Flash
- 2MB PSRAM
- WiFi connected
- 2.4Ghz WiFi built-in
- External Antenna for best WiFi reception possible
- 2x 5.08mm Data output output terminals
- 2x Individual level-shifters
- Re-imagined output stages, no more resistor switcher but long cables with seperate or bundled cables!
- ESD and OverVoltage protected
- A continuous direct short to the data terminal with up to 48V will not kill the hardware
- ESD events (lightning storm, etc.) are also protected!
- 3x 5.08mm Power output terminals
- Accepts up to 14AWG with a wire ferrule
- Individual per channel “relay” On/Off control
- Turned off on the + side so when off nothing can short!
- Individually fused per output channel
- User replaceable fuses
- 2x 5A channel
- 1x 10A channel
- Various internal circuit fuses
- In the case a component fails there are various internal circuit fuses preventing a catastrophic failure
- Auto and True 5V-48V support
- Full range so compatible with newer 36V and 48V LED offerings!
- True means also allowing voltages below 5V so that when voltage drop occurs to say 4.5V the controller doesn’t crash and still provides a stable 5V data output signal to the LED ICs.
- Designed for high current
- Suggest max power is 15A but the board can easily handle the max 20A current possible with the default fuse set (it is not recommended to increase fused values). The controller has been lab tested up to 30A without any issues.
- Dual Power-In feature
- Allows for 2 power supplies to be connected to keep the board running in “standby” mode while the large LED power supply is automatically turned on and off.
- Large 6.35mm main power input terminals
- Accepts up to 12AWG with wire ferrule
- USB-C as a second power input
- Accepts USB-C 5V 1A
- Large 6.35mm main power input terminals
- Allows for 2 power supplies to be connected to keep the board running in “standby” mode while the large LED power supply is automatically turned on and off.
- Built in Microphone
- Various expansion options
- Button Terminals
- 4p 3.08mm pluggable terminal with 2x HW debounced button input (pulled-high) and 2x GND terminal
- External relay port
- JST PH
- Pluggable cable delivered with controller
- Provides (always) 5V, 5V trigger (max 500mA) and GND
- JST PH
- I2C port
- Stemma QT compatible I2C port
- 3V3, GND, 2x GPIO
- QEXP port
- 3V3, GND, 4x GPIO
- Connect various accessories, sensors, etc.
- 3V3, GND, 4x GPIO
- Button Terminals
- 100% compatible with WLED, ESPhome, FastLED, Moonlight, etc. etc.
- It’s your hardware, you can run whatever software you like and is best suited for your installation!
- Fully stress and error tested
- Designed to be safe!
- CE certified
Suggested LED handling capabilities
Although the ESP32 can handle a good amount of LEDs it’s capabilities are limited. The suggested max amount of LEDs per board are also dependent on the software you are running on the board.
- WLED
- For WLED a total of ~2000 LEDs divided over the 8 output ports is suggested
- ESPixelstick v4
- For ESPixelstick a total of ~3000 LEDs divided over the 8 output ports is suggested
- ESPixelstick is much “lighter” firmware and it handles the processing of the LED data differently allowing a bit more performance
- For ESPixelstick a total of ~3000 LEDs divided over the 8 output ports is suggested
- FastLED is as of yet unknown what is max recommended for good performance
- Moonlight is as of yet unknown what is max recommended for good performance
