![]() ![]() The term "mount" can refer to several things: how the connector is mounted in use (panel mount, free-hanging, board mount), what the angle of the connector is relative to its attachment (straight or right-angle), or how it is mechanically attached (solder tab, surface mount, through hole). Mount - This one has the potential for being confusing. It's important that you select a connector with a suitable life for the application. A USB connector may have a lifetime in the thousands or tens of thousands of cycles, while a board-to-board connector designed for use inside of consumer electronics may be limited to tens of cycles. Datasheets usually present that information in terms of mating cycles, and it varies widely from one technology to another. Mating cycles - Connectors have a finite life, and connecting and disconnecting them is what wears them out. It's also much easier to browse his selection to find the most appropriate parts.The pitch of the pins on the headers on a standard Arduino is. His prices are comparable (and sometimes lower) than Digikey and Mouser. ![]() Great Plains Electronics primarily supports pinball hobbyists.Molex connectors/pins/housings: Great Plains Electronics*, Digikey, Mouser You can always cut them down if you ever need smaller ones. Buy a few extra housings with the largest number of pins you foresee needing.Using keying plugs in your connector housings will help you avoid accidentally plugging housings onto the wrong headers. The board connector's use different key patterns to differentiate the various types of connections (ie. Not only do they hold the header in place, but they also make it obvious which way to plug on the header. Crimping a lot of pins with a hard to use tool isn't fun! Note: Not all connectors are used on all boards.These boards use the following molex connectors: Note: If using this board to drive a lamp/led matrix, connect J11 to the cathode side of your LED matrix (or the return side of your lamp matrix).Note: If using this board to drive a lamp/led matrix, leave J4 unconnected.Note: If using this board to drive a lamp/led matrix, connect J7 to the anode side of your LED matrix (or the input power side of your lamp matrix).Note: If using this board to drive a lamp/led matrix, leave J3 unconnected.Connect your voltage source (5V-20V) to the Bank A Power Input connector (J5).Ensure F2 has a properly rated fuse for your application. ![]() J11 connects to the Bank B transistors, which complete the path to ground when activated. Connect each of your devices to the desired pin in J11.Use the Bank B Power Output connector (J4) to supply power to the devices you want to control with this board/bank.Connect your voltage source (5V-80V) to the Bank B Power Input connector (J6).Ensure F1 has a properly rated fuse for your application.J7 connects to the Bank A transistors, which complete the path to ground when activated. ![]() Connect each of your devices to the desired pin in J7.Use the Bank A Power Output connector (J3) to supply power to the devices you want to control with this board/bank.Connect your voltage source (5V-80V) to the Bank A Power Input connector (J5).Refer to the P-ROC FPGA specs for more details on the command format. When using a P-ROC, boards with addresses greater than 7 must be accessed directly by software by writing the appropriate data to Module 3, Address 0xC00. Note, P-ROC drivers can be configured into driver groups for the first 8 board addresses (0-7).Dipswitches 4:1 map to board address 3:0. Set the address (dipswitches 4 through 1) to a unique address.Connect the the Serial Output connector (J10) to next board's Serial Input connector (J9).Connect the the Serial Input connector (J9) to previous board's Serial Ouptut connector (J10) (unless this is a master-combo board).Note - These instructions also apply to the master portion of master-combo boards. Connect the Master board's Serial Output connector (J10) to next board's Serial Input connector (J9).Simply using a current limiting resistor is NOT sufficient. If you are using a 5V controller, be sure to level translate the signal before it reaches the Master board. Note, the Master board's data input pin (pin 1 on the ribbon cable header) is a 3.3V input.If you're not using a P-ROC, connect your controller's serial data pin to pin 1 on the Master board's ribbon cable header and at least one ground pin from your controller to an even numbered pin on ribbon cable header.Master board J8 connects to P-ROC J34 header via the 16-pin ribbon cable that came with the board.Install the Master near the P-ROC (or other controller). ![]()
