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/max 9V/36V when power is routed to driver board; min. 12V for VBus 12V)
* 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
* SSRs: CPC1976: "Datasheet":https://www.tme.eu/Document/905abd07f76f05090463070be7486d83/CPC1976.pdf 2A_rms continuous -> 460W; 1,8KW; zero cross (CPC1976YX6 is non-zero-cross)
* Power measurement: INA228AIDGSR
* 12V/5V: L7987
* 5V I2C: PCA9306DCTR
* High power: SSR-2528ZD3 kann 25A; Steuerung via 5V; habe "RA2425-d06":https://www.reichelt.de/de/de/shop/produkt/solid-state-relais_ust_3-32vdc_ulast_24-280v-22691, sollte identisch sein.
* Ideal diods: MAX40200 for VDD from VBAT; LM74700 for VBUS
