After delivering the first batch the customer wanted some slight changes, most notably a configurable board which could either talk to itself or either end of the communications system the Eaton Leonard benders use. So, after poking with the breadboard on Friday and documenting my findings on Saturday I set to work drawing the board. It&#8217;s the same dimensions and the power and data connectors are in the same place, but everything else is different.<\/p>\n<p>I had initially tried to use a resistor network to make soldering easier, but that was going to make connecting everything in such a small space very difficult, so I went back to discreet resistors.<\/p>\n<p>I might change the LEDs and the resistors connected to them. (This will be determined tomorrow.) There also might be a product name change, part number change, and some of the labeling is still up in the air. Other than that, I&#8217;m pretty happy with it. Hopefully I&#8217;ll order the first run of boards by the end of the week.<\/p>\n<p>I still have to finish working on the photos from the Selfridge airshow this weekend and upload them. That&#8217;ll be another night, I think.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>RS232 to Eaton Leonard Level Shifter v2.0 Draft(Click image for 600dpi version&#8230;) After finishing up the work I had to do today I began working on v2.0 of the RS232 to Eaton Leonard Level Shifter.
