How to: Eagle CAD to 3D Rendering Views

Today I learned how to create 3D renderings of Eagle Boards.  I’ll share with you how I got this image below.



You’e probably seen this board design, it’s from my last blog posting. It’s a split +/-15V DC/DC Converter power supply, which also accepts our FAB-1248 Plugin module (for 48V DC output).

Sample FAB Setup – Power supply and other stuff







Here are some photos showing the FAB1215 Power Supply Module powering some FAB modules via a ribbon cable.

Here’s a photo of our FAB1215 Power Supply Module, outfitted with our DC-1248 (+48V converter module).

I finally got the chance to test the 48V power supply by hooking up our FAB2010 XLR Input Module, FAB2110 Input Transformer Module, and FAB3010 XLR Output Module, using them as a pass-through before going into an API 512C preamp.   But instead of turning on Phantom Power on the API preamp, I used the 48V source on our FAB module.

FAB2010 XLR Input Module Prototype Testing

The moment of truth… powered up our FAB2010 XLR Input Module for testing. I’m happy to say it works great.  The Logic Control Inputs for the 20dB Pad and Phantom Power works as expected.

So basically, if you want to enable PAD or PHANTOM POWER, all you need to do is apply a small voltage to it’s respected logic pins on the board. See photo below.  A logic level control voltage can be anywhere from +3.3V to 5V up to your V+ level.  These can be switched from hard-wired switches (latching type push-buttons), or from a microprocessor or logic gate chips (TTL or CMOS type).

How it works

XLR Input + Input Transformer Module Combo

Here’s a photo of how the FAB2010 XLR Input Module and FAB2110 Input Transformer Module connect to each other.

I added a 2-pin header on the FAB2010 XLR Input Module. Later, I’ll show you how to connect those pins to your switches to control -20dB Pad and switching of Phantom Power.  I’ll also show you how to connect these pins to a Microprocessor, like an Arduino (AVR) and show it’s logic level capabilities.
