Simple 3D-printed NRF remote - Arduino controlled

check out this unit, 5v 2A e-bike usbport, there is a compact PCB inside (if desired, I can post a picture later today :wink: ) https://nl.aliexpress.com/item/Elektrische-Bike-USB-Charger-Output-5-V-2A-Voor-Mobiele-Telefoons-Ebike-36-V-48-V/32860737409.html

Hey guys, Iā€™m just getting into all this electric skateboarding stuff and would like to know if anyone has made a video or has an instructions list containing something similar to a step by step of how to do this. I am considering making this alternatively to buying a winning v2 remote. I have a 3d printer so the case etc is no probem itā€™s just the electronics inside that are kind of scaring me out of this. Thanks!

Yep, itā€™s all buried in the thousand threads above :slight_smile: @solidgeek has a tutorial: https://solidgeek.dk/docs/firefly-remote/getting-started/ and @seethebridges has a video tutorial. The first 3 parts are out already w/ more coming: https://www.youtube.com/watch?v=N032HqxeymA

My Oleds should be rated 3-5V, and they work from 5V rail when powered by usb (real measured voltage around 4.7V). I think the logic pins cant take over 5V thats why they fry when using my shitty boost converter. Or maybe because the boost converter doesn fit properly, something is pressing wrong place on it

Thanks so much!

One more question, I was just looking at sourcing all the parts and the nrf24 module on the parts list is "no longer available. I tried to find one but was unable to. Does anyone know where I could purchase one of these?

And if you canā€™t wait 30-50 days you can get them next week for a bit more cash: https://www.ebay.com/itm/1Pcs-2-4G-NRF24L01-PA-LNA-Wireless-Module-Ceramic-Antenna-1-27mm-For-Arduino-US/162862165321?hash=item25eb576d49:g:jrgAAOSw8d5ZRXQZ

When ordering from aliexpress, I always use the aliexprees standard shipping, it costs like 2,50e and delivery time is reasonable 12-21days to Finland. And use the same shop when ordering many items so only one shipping cost is added

I was unable to locate the code for the arduino, Iā€™ve never used one before so is it just as easy as plugging it in and uploading the code? Also how does this connect to the ESC, and do I need more parts do make the connection. Thanks again for all the help Iā€™m really new to this skateboarding thing. Here is the link to the ESC if needed products/torque-esc-bldc-electronic-speed-controller

Thereā€™s the code, and youā€™ll need to get the arduino IDE and a couple more libraries

Thanks! Appreciate it. Do you know how the remote connects to the board?

both the remote and the receiver have an arduino on board with a microUSB jack on them. Just watch the videos. Itā€™s all in there

Sorry for all the questions. Are the videos on @solidgeek youtube channel as i couldnā€™t locate them :frowning: Is it possible you could link them?

Thanks again so much :slight_smile: !!!

I couldnā€™t seem to find any of this in the thread above so here it is. I was wondering if you could put a USB C female jack instead of the micro USB one in the remote to charge it. Iā€™m no electrician or anything and I know thereā€™s not a whole lot of space in that area but Iā€™m curios if one of these would work? If that doesnā€™t fit could you also use one of these? Iā€™m not sure about the pin layout but couldnā€™t you directly solder onto them as to reduce space?jpg_640x640

Yup should work fine. Only issue really is usb-c has the capability to have more than 5V supply (can go up to 20V according to Wikipedia) but so long as there is no connection to the CC pins it should default to 5V 500mA. In theory should work fine though (plus something will be able to plug directly into a MacBook pro 2017) https://en.m.wikipedia.org/wiki/USB-C

Would just check the vbus and G pins with multimeter with it plugged into the adapter(s) you plan to use to charge.

I would be attaching the wires to these ports correct?

That USBc port is waaayyyyy too big to fit in the remote because of the PCB around it
