DeuceEFI sent me a Jaguar A3 two weeks ago and all the additional parts arrived from DigiKey last Friday, but the priority was on my girlfriend and her daughter (who were both in town over the weekend). I was relieved that somehow all my electronics parts and tools were spared the 4-year-old's grip of curiosity, but it turns out that she left her calling card on my "static dissipative (work) mat" just before departing today. Love that little girl.

ROFL!!! Nearly woke the mrs then! :-p epicly funny.

I began my A3 Jaguar build last night (Oct 30). Here are the more frequently used tools so far, though an eyepiece has also been useful.


Steps 1-6: DeuceEFI already took care of baking the fine-pitch ICs and SMD components, pre-shipment. All look good.


Steps 7-10: The digital and analog power supplies were soldered into place and tested at 4.99VDC.


Steps 11-12: These were mostly taken care of by DeuceEFI as well and I opted for a standard sized USB-B socket due to frustrations I have with the design of micro-USB sockets.


At the moment I want to check with Deuce about his UART jumpers before finishing up step 12 and moving on.

She has a habit of drawing anthropomorphic hearts right now. Quite the active artist for a 4 years old.

You could have taken that copy/paste/dump when it arrived without the power supplies ;-) Did you connect any freeems or loading sw to it and talk/get it to talk back? If not, do :-)

A couple of points:
1. I hand soldered the ICs, your board hasn't been through a reflow oven. I used the one pin at a time method, not the drag solder method.
2. Once you verify that the regulators are working, jumper JP9 and JP10 to connect the board to the MCU and Analog supplies and then connect a USB cable and open EMStudio, you should see it connect. It did for me when I did my testing of the boards before shipment.
3. I shipped your board with the FreeEMS-Vanilla Benchtest firmware so you should be able to use MTX to run the benchtest to see the output LEDs flash once you jumper the MCU outputs to the Injector inputs. We need to ask malcom2073 to add the benchtest feature to EMStudio.
4. It is looking good so far, keep asking questions along the way!

Nice work! :-)

Edit: No hardware additions tonight, but here are a couple snaps leading up to Step 15.
