Designed breakout PCB for generic 16-SOP IC (in this case, for the CH32V003A4M6 MCU). As a test, embedded some crosses and text in the copper layer to attempt that. This is for testing of the IC to be used for the stepper motor controller.
Created logic-level-shift PCB design with built-in LED indicators and ordered on OSHPark. 
Created 03007-003 PCB design for a single H-bridge stepper driver using SMD components. Submitted board for fabrication at OSHPark, though this could technically be fabbed in house. 
Reversed the diodes on the first soldered board and retested, which still showed a short. Realized I had some of the P and N channel MOSFETs installed in the wrong spots. Would have been good to label them on the silkscreen. I just soldered 4 other boards with the correct components and they seem to work, though I have not fully tested them all with coil loads. I did not have enough P-channel MOSFETs so I reused some old (potentially shot) ones. I have marked them to help identify them if an issue arises in the future. I updated the schematic and PCB design to reflect these revisions, rolling the part rev to 03007-001-A. It counts as a revision, not a new part number because the board has the same form, fit, & function as the sibling -001. 
Printed a set of 4 PCB holders and began to electrically test the first board. After some debugging, realized that the schematic and front silkscreen have the diodes going the wrong way, which I installed the diodes to match. These 6 components need to be desoldered and reversed and the board silkscreen design technically revised. 
Modeled and submitted for print a holder for the 03007-001 stepper driver PCB. 
Filed off burrs and soldered components to one of the stepper motor driver PCBs. I oriented the screw terminals in a consistent way for easy wire installation, but that does technically deviate from the schematic. 
Received 6 of 6 (no extras) 03007-001 stepper coil-driver PCBs from OSH Park. They arrived in 15 days. The communication from the company was far better than DKRed. The board quality is decent, and the price is comparable. Boards (purple cheapest and default option) do come with jagged edges where they are broken from a larger PCB platter. I do prefer them to DKRed. 
Designed and ordered 6x stepper motor driver PCBs from OSHPark to compare against DKRed. See CAD files. Submission was seamless, and they give better visibility into the order timeline. Pricing is comparable to DKRed. I decided not to expedite.
