Amazing! Thanks for releasing the code and files for this - amazing contribution. I was about to build the Firefly nano but really wanted the ESTOP feature so I will build this one if I can figure everything out. I never did this kind of software development but I work in tech and I know C. Hopefully I can contribute in the future.
With the files you provided am I able to get a PCB made for the transmitter and receiver? If not, is it possible to build this without any custom PCBs like Firefly Nano?
So yeah it’s definitely possible to make it work without the PCB. It’s just more difficult and not as reliable (arguably). Stefan’s included the PCB files so you should just be able to use something like jlcpcb and get them made
Do you think you’ll make another production run before… say April or May? Won’t really be riding reason here for a few more months so I don’t mind waiting…
If anybody’s looking to build this remote, keep in mind like @Arek said to keep the soldered pins as flush to the pcb as possible. Otherwise you the pin will puncture the battery and glitch everything mid ride…
Also I first trimmed them (with a flush wire cutter) and THEN soldered it, as a result sharp pins are covered with rounded solder.
As a another layer of protection I will add a layer of that fish paper that is intended for battery isolation use.
Those mounting holes on the bottom seem kinda broken, way too close to the PCB, manufacturer may complain.
Did you add a low pass filter for the RF module?
Pls put there USB type-c, it’s time to switch from micro
Have you used a bit bigger holes for the connectors?
I see all tracks the same width, power lines should be a bit thicker.
Also would be nice to have a SMD antenna.
That USB connector has two big pads, slap 4 tiny vias on each so it will be stronger.
You decided to keep THT hall sensor?
Thought you going for SMD one…
You added 3rd mounting hole, thanks!
