Corona is an LED-driver board to control two independet chains of 13 LEDs each from a supply of 6.5V to around 14V. Corona is intended as a controller for ringlight for macro photography, but can be used for other lighting tasks as well.
Features:
- Two independent LED-drivers for rows of 13 LEDs (43 V) at about 25 mA
- Atmel Mega 88 Microcontroller, to add more features in software
- USB connector, to control corona via a PC
- Switches and infrared receiver to control corona without a PC
- some GPIO to add further devices, such as photoelectric sensors
Kits and boards are available shortly via the Lochraster.org-webshop.
