You need to wire the gnd from the servo also with the ppm.

I will send some pictures tonight if you want

That would look like this right?

Any objections Ludwig?

You may also need to bridge the GND

I’ve not received mine yet. I ordered the day they came out. My order went to status “complete” on the 16th of June but no further updates. I’ve sent an email to openfoil to follow this up a couple of days ago but as yet haven’t had a reply. I’m hoping to hear soon. Was yours to the UK?

Together with the fabulous support of @heiguga we were able to debug an solve the issue. It is in fact in software and I will upload a new version as soon as I am back from vacation. Until then please send me a DM if you have a similar issue.

I won’t receive screws and 18650 battery before 3 weeks.
If I finalize now with old 18650 and bad screws , would it be possible to change the battery later, without damaging the PCB ? I can print all parts again.

ludwig_bre · June 30, 2025, 10:42pm

You can use different screws on the external parts like trigger and toggle and change them later
Battery can not be changed after you have filled the remote with the potting material.

hello ludwig is it possible to put the gps antenna between the esp 32 and the remote antenna, it is to be sure it will be no interference. thx

ludwig_bre · July 1, 2025, 9:15am

I think that is too close to the antenna still… You can try but maybe you will have less range or bad GPS reception
Better would be to have the GPS Antenna in the back of the remote, behind the display. You may need to change the housing a bit to make it fit.

First, thanks for great project and documentation! Unfortunately my kit would not power on. I tried first with the 18650 battery, didn’t work, then connected to my lab power supply, the remote does not draw any current, no matter the switch position. How can I troubleshoot?

ludwig_bre · July 1, 2025, 3:23pm

Hey, there are two things you can try:

Connect USB supply, as the battery protection IC sometimes needs a “boost” to enable the battery
There may not be any firmware on the remote
In that case upload the firmware like shown in this video (timestamp 39:45 min)

However take the merged file and upload to 0x0, not 0x10000 like in the video

Important Update Regarding Screw Packaging

Dear OpenFoil / BREmote Community,

We want to inform you that we have identified a packaging error in some of our BREmote V2 DIY Kits — a few kits were shipped with missing screws.

We sincerely apologise for this oversight. We have already prepared additional shipments with the missing screws, and they are on their way to you.

Thank you for your understanding, patience, and continued support. We appreciate you being part of our journey to make the best DIY eFoil solutions possible!

If you have any questions or concerns, please don’t hesitate to reach out to us at support@openfoil.com.

Thank you, I got a little bit further. With the USB cable connected, I was able to flash the firmware. I used V2_Integration_Rx.ino.merged.bin and offset 0x0 as recommended earlier in this topic. However after the flashing the remote did not show any signs of life. In the serial terminal it prints this:

ˍA#�ESP-ROM:esp32c3-api1-20210207

Any idea what could be wrong?

EDIT: I used the wrong firmware, the remote is TX! Now the display is showing something!

hello ludwig i mount everything and nothing happen, but got a mac and the flash downloader is for window need some help

ludwig_bre · July 2, 2025, 2:20pm

I am not sure if I have a solution for that… You can try to use Arduino and compile the files yourself, by opening the project with Arduino, install libraries and upload… But I think easier is to get access to a Windows PC somewhere
