[[RTC-Test]]
Helios is "Mainswitch" and "CANSwitch" combined with some features added:
* RTC
* 12V VBUS (optional)
* 4 PWM channels
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
* Usage of LDB-350/LDB-300: Output 2 ~ 40VDC
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

* Power measurement: INA228AIDGSR; 3.63EUro
* 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 with seperate diode
* LDB-350L: 6.60 Euro
* LDB-300L: 6.54 Euro
* SK57750AL; Ø50mm; H:50mm; 5,61Euro
h2. Errata
* There is only one global 'Enable' line. Not a big deal, the power supplies can be switched off anyways. None would also work.
