Dear DIY enthusiasts,
I am proud to present the SRGBmods LED Controller v1 to you, a reworked/enhanced version of the famous Pico LED Controller that has been around for a year now!
The SRGBmods LED Controller v1 is an entry level / low budget DIY (do it yourself) ARGB controller exclusively designed to be used with SignalRGB!
-
Its base is an affordable (MSRP around $4.00) Raspberry Pi Pico micro-controller that makes it possible to drive up to 800 leds at mid to mid-high frame rates.
-
Adafruit Feather RP2040 SCORPIO, a micro controller unit based on the Pi Pico’s RP2040 chip that features 8 dedicated pins for driving led strips with 5v logic, so no additional level shifter is required is supported as well. (recommended for beginners!)
-
8 GPIO pins within a subsequent row can be used to connect your devices to it!
-
Color Compression can be enabled in the device options in SignalRGB to raise the frame rate at the cost of a reduced color spectrum! Not recommended for fast effects and/or low brightness!
Further details:
Details about Hardware Lighting
Status LED and Hardware Lighting can be configured on-the-fly directly in the device options in SignalRGB!
A word of warning: EEPROM has a limited write cycle count per address, DO NOT constantly change the Hardware Lighting settings!
