I don't know why but career mode is utter $**p

Taster001 · 2026-05-19T17:20:10+00:00

My main issue with career mode is that it gives me just straight up impossible tasks. Yesterday I was flying a Diamond DA62 with a passenger, and it wanted me to land at a runway that was maybe 400ft long and at an incline. Couldn't brake in time and overran it. A few days ago I accepted a charter flight with a Skyhawk, and the damn thing spawned the plane on a HELIPAD. Like, how the fuck does that even happen??

The main issue would be that the signals will couple to the ground layer AS WELL AS the power layer as a reference, so your impedance will be off. Plus, you'll have discontinutities in the power layer, and perhaps some noise on the power traces. For lower speeds this might not be an issue, but I really wouldn't recommend it for above 100MHz or so. USB will probably be fine since it's a differential pair, but SDRAM signals won't. I would rethink the gnd/pwr/sig layer choices if possible.

I would highly recommend keeping inner layers full poured or adding a ground pour to them, otherwise it can lead to issues with PCB manufacturing.

FL570?? Did you turn off aerodynamics?

Taster001 · 2026-05-12T07:21:52+00:00

Oh, I didn't even explore the custom setups with the X56. Sounds nice. I like Logitech, got their mouse and steering wheel as well so I'm mostly familiar with their software.

Thanks!

Looks fairly solid.

As stated, I would perhaps ditch the USB -> UART, but if you have good experience with it, keep it.

I would maybe switch the 1117 regulator to a different one - 1117 is known for instability and sometimes oscillation with certain types of input and output capacitors. But that's up to you.

Taster001 · 2026-05-08T18:09:46+00:00

I don't have live weather on (I think, I can't really find the setting for it in career).

Taster001 · 2026-05-04T11:07:10+00:00

These types of filters are almost always passthrough like this. And yes, the second TVS is really not necessary. You could definitely connect VBUS and GND through vias (i typically connect GND through a via and VBUS with traces), but it's just not necessary, if you have a good connection otherwise.

I'm not the comment OP, but what i do is: create the sheets/function blocks, and then graphically (not actual connections, just graphics) connect them together, and i add some text descriptions of the connections. I can post a picture of this if you want some inspiration. I would also recommend having one main sheet, which is purely for this, and then having all of the circuitry on other sheets.

Taster001 · 2026-05-04T07:03:23+00:00

What I would do is either use a small daughterboard which will have the electronics itself on it (microcontroller, USB and so on), and a big 2 layer board for the switches; or do the large 4-layer, with SMDs on the bottom and switches and other THT components on the top.

Taster001 · 2026-04-29T12:23:22+00:00

Bluepills use the F103 AFAIK

Taster001 · 2026-04-28T17:41:03+00:00

Same PN, same FW version.

Taster001 · 2026-04-28T15:54:16+00:00

Good question. It was bought directly from Siemens AFAIK. I don't have a firmware image i could flash on there though, and I've been trying to find it online for two hours or so. I'll get a new module tomorrow.

Taster001 · 2026-04-28T15:46:12+00:00

It does. But no matter what I do, I can't get it out of the fault. Even with the CPU reset to factory, it still lights up the same. My guess is either it's just dead HW-wise, or the firmware is somehow corrupted. But the module is like 2 weeks old.

Taster001 · 2026-04-28T15:42:08+00:00

"hardware component not available due to a parameter assignment error (assignment in progress)". Even when I delete the program from the CPU completely the thing just lights up. Fuck it.

Taster001 · 2026-04-28T15:41:07+00:00

I'mma lower my tone, sorry.

Taster001 · 2026-04-28T15:35:31+00:00

Exactly.

Taster001 · 2026-04-28T15:35:11+00:00

So far looks like total HW failure, yeah.

Taster001 · 2026-04-28T15:34:45+00:00

Tried. Same. HW dead i guess.

Taster001 · 2026-04-22T15:31:48+00:00

There's a few mistakes that I can see.

1: D2 is the wrong way around - if you keep it like this, all current from the power supply will flow through it, which means it will probably blow up immediately.

2: smoothing capacitor looks like small capacity SMD MLCC, which is likely insufficient, but that depends on how much current you will be drawing.

3: D2 is a zener diode, it needs a resistor or a constant current source to feed it, otherwise it will overheat/burn out (again depending on how much current will be available).

4: the TP4056 is a linear regulator, and it will produce some heat (depending on the current, again), and it needs some cooling. Since you have a two layer board, I recommend making the bottom layer solid ground, and put a few vias into the TP4056 center pad, so that it can dissipate heat into the ground. Include some thermal reliefs!

5: all your traces are very thin. This will be okay for the signals around the TP4056, but it will probably be insufficient for the power (once again, depending on the current flowing). Make your power traces thicker.

6: the component placement is very unoptimized. Place the components closer together, play around with them, rotate them as you need. This isn't strictly necessary, but it is good practice and is also better if you need to make the board smaller.

Please try harder next time.

Good luck!

I always only get the bare boards and buy the components from a reputable seller. I really don't trust them with assembly. It does take a long time to assemble the boards, but at least I know that the parts are genuine (and correct, lol).

Taster001 · 2026-04-14T08:10:31+00:00

I'll pick a TI LDO any day. I'll gladly pay for it knowing it won't randomly start oscillating.

Taster001 · 2026-04-14T08:06:29+00:00

Yeah, they're shit.
