Boost converter 12V to 24V
A boost converter board is based on the classic “step up” schematics, features a 555 IC and has a power indicator. It is powered by 12V5A line and can provide up to 24V1A. 24V1A is being output to two connectors. It can be used to power up solenoids in "Spike and Hold" mode or in conjunction with any other device that needs 24V. The board can be powered by the central hub or the 12V5A breakout board.
As mentioned in the schematics, boost converter can be assembled with different components accounting for what you have at your disposal. If you are building the boost converter as a discrete module without solenoid control board, you are highly likely to find yourself with a lot of 100nF capacitors and 47 Ohm resistors as they are used heavily in BeeHive. If you are building the booster and you are going to build a solenoid control board, you may want to order more 10nF capacitors and 330 Ohm resistors. The values of capacitors and resistors are interrelated and they act as a reference for a frequency that 555 generates. It should be about 100kHz. The reason why this frequency was chosen is that 555 is still stable working with this frequency and components such as inductors and capacitors are much smaller than on lower frequencies.

Do not connect or disconnect connectors while power is ON. All adjustments must be done ONLY when power is OFF.
The LED next to the 12V5A connectors indicates whether the board is powered or not.
