Push Board
From Livid Wiki
Push comes in two sizes and configurations, small and medium. We have two size button pads that correspond with these boards.

Push Medium (4x1)
This board comes in a grid that is vscored so that each individual button board can be separated or the user can break apart a series of buttons into any size section desired. This board is 1"X1" and designed to work with the medium Livid Button pads. When left connected to one another, these button boards will give a 1" center to center spacing. The boards are designed on a 0.1" pin spacing layout so that the pin holes will work with common 0.1" pin headers, terminal blocks, and perf boards. By soldering a pin header on 2 sides, the boards will plug right into common breadboards so that the user can build a project. Button boards include a button contact pad and connections and an indicator LED pad and connections. Each board has a set of four connections labeled BR,BC,LR,LC. BR and BC are for button rows and button columns when building a matrix.
A. Connections
- Push boards have four connections labeledB R,BC,LR,LC. There are matching connections on all four sides and they are all connected together. For direct connect buttons, BR and BC are each leg of the button. For button matrix connections BR and BC are for button rows and button columns. LR and LC are for LED rows and LED columns when building a LED matrix. To connect a series of boards the user will need to solder jumpers between at least one matching connection on a side. For a button matrix, button boards are daisy chained together and then the beginning board of each row is connected to a row pin hole of the Breakout board and the beginning board of each column is connected to each column pin hole of the Breakout Board.
B. LED Connections
- The indicator LED circuit uses either a 3mm through-hole LED or optionally a 0603 surface mount LED. Looking at the picture, you'll see a semi-circle around the through-hole LED, with the left edge flat. This flat edge is the negative connection (cathode) for the LED, so the the short leg of a thru-hole LED goes in this hole.
C. Surface Mount Diode
- A button matrix situation will require a diode. D1 is for a surface mound diode (SOD-323 size) These diodes are commonly found on http://www.mouser.com or http://www.digikey.com. The line of the diode (indicating the cathode) should be in the same direction as the line on the board. Alternatively, you also use a through-hole diode on D2.
D. Thru Hole Diode
- For use as a direct connect button, the user will need to solder a jumper wire between both pin holes of the D2 through-hole diode connection. The line of the diode (indicating the cathode) should be in the same direction as the line on the board.

Push Small (4x4)
This board comes in a grid that is vscored so that each individual button board can be separated or the user can break apart a series of buttons into any size section desired. This board is .8125" X .8125" and designed to work with the small Livid Button pads. When left connected to one another, these button boards will give a .8125" center to center spacing. The boards are designed on a 0.1" pin spacing layout so that the pin holes will work with common 0.1" pin headers, terminal blocks, and perf boards. For direct connect buttons, BR and BC are each leg of the button. For button matrix connections BR and BC are for button rows and button columns.

Indicator LED Circuit
Indicator LED's are LED's that can be turned on and off by the Brain by sending MIDI or sysex messages. The onboard indicator LED circuit the includes a set of pads for a single LED and a set of contacts labeled LR and LC. Indicator LED's are driven by USB power and do not need an external power supply. Indicator LED's are driven from the Brain and can also be found on the Push boards. Do not confuse the backlight LEDs with the Indicator LEDs. The backlight LED's are not part of the Brain, only the BYOB boards and only provide 12v dc backlighting.
