And here's me just ordering one of the 6 pin because I'm tight....Ordered 2 lots of the 6 pin and 2 lots of the 5 pin as I also want to play around with my CANBUS modules at some point (from AliExpress)

I order multiples as I am ham-fisted and likely to mess it up at least once ;-)And here's me just ordering one of the 6 pin because I'm tight....
I've not taken mine apart, but just because the comms back from the head unit to the controller in the drive is CANBUS, doesn't mean you can't use a different switch to the HMI/screen.
Does the github repo have the wiring from the switch to the display too (the purple one)? It's a six pin connector, and there are 3 buttons. So could we use any 3 button individually switched controller? It all depends on how those switches work, are they basic digital inputs or some kind of resistor based network where each combination of switches gives a different resistance?
The documentation for the CA Slim aux input has a lot of info, I've attached it to this post so you can have a look.
I certainly agree that the bafang one is very vague though. I'm using the DP160 on my E10:

It is quite tall and the clamp breaks easily (I've 3D printed a hacky replacement for it). The whole display is a rocker switch, so it's very easy to press however.
On a side note, I've got a couple of ESP32 modules with onboard CANBUS that I was toying with the idea of using to make a headless type HMI with just some switches on the bars, but not got around to it yet (too many projects!). As the CA switch seems to work on voltage threshold (not discrete digital inputs), it would easy to use without modification. I'm not totally sure how the On/Off works on the controller either unless it's the same as the BBSXX where you just short a connection.
@Hagbard and @captainhightop - thanks to both! I was thinking next step was buying a second one as backup to play with or search ES. Awesome info. About to head on a trip but following, especially as it seems like the remote really is a simple switch device.
I am curious as to your impressions of the DP160 - I didn't realize it was a rocker switch and through they were trying to be 'cute' yet way out of touch, and it was a touch screen input. Seems like less that thrilled with it? Only 5 PAS levels/can't set to 9?
If the remote is simple connections, I think I'm more inclined to try to Grin or Specialized part, but had completely discounted the DP160 - I suppose on incomplete info.
That's what I (and I think @captainhightop ) already have. I'm not a fan of that remote and the screen is really crap in sunshine, not to mention that the underbar nature of the clamp has always felt a bit weird to me. I don't hate it, but I do feel like it could be better.
@thaeber that looks neat, but I still think that the buttons are in the wrong orientation, i.e. they should be horizontally placed rather than vertically. It's a bit like underbar dropper levers vs those weird ones that sit around the bar, with the latter being ergonomically rather awkward. Do we have any idea how much that's likely to cost?
I might have to do a bit of CAD to mockup (and 3d print and try out) some possible button layouts, though I can't help but feel that accomodating a brake lever, a dropper lever and 3 buttons might be rather challenging and I'm really not sure that I'm clever enough to work out how to do it!
True, the remote is kind of chunky. The display has a nice format and safe position slightly below the handlebar, I like that. The visibility is the problem. Yesterday I played around a little with the settings. I changed brightness to 75%, and AI Senitivity to „0“. Now the display does not adopt to change of light conditions and is bright enough to be visible, even when sunny. Big improvement.That's what I (and I think @captainhightop ) already have.

Sounds promising, more so than the Shimano steps one, that looked like just 2 wires to me (DI2 I think they call it)@captainhightop Look at this:

6 pins out.....Interesting.....
If there would be anyone that could work on the connector of the giant remote to be able to connect it with the dcp240 display I would definitly pull the trigger . Maybe someone could help me out?Sounds promising, more so than the Shimano steps one, that looked like just 2 wires to me (DI2 I think they call it)
Also looks user serviceable with the screws on the side
We could do with someone who has one of those switch units, who can disconnect it and check the wiring with a DVM for continuity when switches are pushed. Also although my tests looked favourable, I'm waiting on the HIGO connectors to properly verify my theory.If there would be anyone that could work on the connector of the giant remote to be able to connect it with the dcp240 display I would definitly pull the trigger .

Let me know if you have more information. I would definitly try it out with the giant remote ✌. Would be a great improvementWe could do with someone who has one of those switch units, who can disconnect it and check the wiring with a DVM for continuity when switches are pushed. Also although my tests looked favourable, I'm waiting on the HIGO connectors to properly verify my theory.
But if everything works out we could cut off the giant connector and add a HIGO! Not sure how long those are going to take from Aliexpress, but I've got a box full of different push switches to try out too.
Looks there is also complete schematic for a HMI and display on there too using the nordic semi microcontroller:Over on ES there's quite a discussion going on re the switching of the start up and shut down of the M series motors, you may want to have a look in.
Bafang M500/M600 thread
Since this seems to be an interesting motor, why not have a separate topic for it? I'll start with three quotes I have found about the motor on this forum, feel free to add more information that you can find. Over the last couple of days I had heard that there had been reports of the M600...endless-sphere.com
Somewhere on this forum was a link to a German guy who had a 3D print of a small spacer that expanded the bar strap to account for the 35mm bar. Equally there used to be on EBay the spacer milled out of Ali.Just a quick question,
Has anyone tried this display?
If not, no worries as I've ordered one as I'm sick and tired of using the Shimano Rip-off display without running a 35mm bar and stem combo.
Not from Ebay mate. Handcrafted German Engineering!Somewhere on this forum was a link to a German guy who had a 3D print of a small spacer that expanded the bar strap to account for the 35mm bar. Equally there used to be on EBay the spacer milled out of Ali.
Bafang DPC241 on 35mm bars
Seen as there is an issue with the clamp breaking if overtightened or not fitted with care does anyone have one fitted to 35mm bars without any problems - does the clamp fit well or does it need to be bent to accommodate the extra width?www.emtbforums.com
Yes, initially my aim was to replace the button cluster with something lower profile (like the giant or specialized one), maybe design and print my own or just splice the cable into one of those.I see. So your intending on using the stock controller but adapt the connectors.
Its plausible that this could work.
Keep us posted @captainhightop
Fair enough.Yes, initially my aim was to replace the button cluster with something lower profile (like the giant or specialized one), maybe design and print my own or just splice the cable into one of those.
Long-term I'm looking at the Nordic semiconductors microcontroller to replace the whole HMI on the bars, but that's a much harder job, although people are working on the CANBUS protocol already.
As it's got ANT and I think bluetooth, I'm hoping that I can use it to add panels to my cycle computer (for battery/RPM etc.) and only have that as a display on the bars with the microprocessor out of sight inside the bike frame (still have the buttons on the bars though).
Still, it's nice to know that I'm not alone in trying to adapt older displays to run on the newer bafang motors.
Hmmm!!I don't think that's the point at all. The idea is to build our own display and buttons, with either improvement ergonomics (in the case of the buttons) or improved capabilites, such as the ability to integrate with a garmin watch, in the case of the display. Going from CANBus to UART seems a little regressive, though it does make sense if your motivation is to use UART displays.
I guess for 2 reasons:Hmmm!!
Food for thought.
Although one does ask the question, why not wait for a well known third party developer to build the display?
Eggrider comes to mind as they've pretty much covered alot of non-mainstream ebike motor brands.

I guess for 2 reasons:
1) Fun
2) It feels like the m500/600 series of motors have been superceded now so the odds of a third party undertaking any significant development on this old platform feels low.
It does still feel like there's loads of potential to still be unlocked with these motors, and as knowledge matures (which it's currently doing at a fantastic rate) we'll see some pretty interesting things.
