h2. Driver board
* One board has 51,24W with the warm LEDs. With LDB350 in general max. 52,8 Watt.
* Supply voltage: 12V-36V
* PWM: 100 ~ 1KHz; 2~10VDC or open circuit
h2. Controller board
* Supply voltage: 5V-60V (min. 12V for VBus 12V; max 36V when power is routed to driver board)
* Provides VBus 5V or 12V (optional, can be powered externally)
* Switch 4 power lines
** [VBus, Plant lamp, Media, illumination] or [VBus, Plant lamp, 2 x Illumination]; VBus can be on of the illumination supplies
* Can start via RTC or Button
* Measure power consumption
* 4 PWM signals for regulator board(s)
* External I2C bus for regulator board(s)
* USB port for configuration
* 3 CAN connectors to have it somwhere in the middle of the bus + Display or to have 5V+12V bus
h2. Parts
* MCU: STM32F072C8T6
