People that ordered Metr Pro CAN modules without GPS should see their tracking numbers via PayPal now. EU folks hopefully receive them before Christmas.
All GPS modules will be tested now to make sure everyone receives a fully working bundle and open orders will be shipped out on Monday.
Each module has its unique pairing code. For the Metr Pro CANs with the SD Card module and 3D printed case it can be seen on the inside of the stacked module and there is also a sticker on the outside. I would advise to note down the pairing code and remove the sticker from the case afterwars to have a cleaner look. When the note is lost there is always the option to open the case and have a look at the pairing code inside.
All Metr Pro CAN modules are deliverd with three cables. One to connect to the CAN-bus and power, the second one to forward the CAN signals to another VESC and the thrid one as a spare cable.
All modules with an SD card shield have a 16GB SD card plugged in and come with an Micro SD to SD card adapter.
Because the CAN-bus is a bus system you just plug the Metr Pro CAN somewhere on the wiring harness. The second port on the module is only there for convenience, so that you don’t have to solder anything when wiring it between two VESCs. Internally the CAN-H and CAN-L lines are connected together.
So for the dual setup it would also be possible to solder together your own wiring harness and only use one of the Metr Pro CANs JST GH ports.
Metr Pro CAN orders with GPS were packed and labeled yesterday and shipped today in the morning. Because of the reported corona mutation shipping to the UK was not possible, but all other orders are shipped now.
The full bundle with the Metr Pro CAN + SD shield + GPS comes in a 3D printed housing with the SD card mounted and GPS connected. The package includes a Micro SD to SD card adapter, a double sided adhesive piece to secure the GPS module, a spare 15cm power cable (on top of the main 15cm power and CAN forward cables) and a longer 30cm spare GPS cable.
When changing for the longer GPS cable make sure that you connected it the right way, so the colors of the end match the following order. If they do not, use the other end.
Metr Can is working with Spintend
But I have a question, does the can port I choose matter ?
I have datas on my app but how can I know if both VESC communicate with the Metr ?
I only connected 1 cable on 1 can port, do I have to connect both ?
Sorry for the late reply, looks like I missed some questions.
@michondr From our testings it also works inside an enclosure but it can take longer for the first fix. It also depends on the enclosure type and where the module is placed exactly, for an example in an carbon fibre board + enclosure it probably will not work.
For best GPS signal and fastest fix it would be best to mount it on top of the trucks like a DAVEGA X.
@Xpress2016 Great that you received the module and it is working with the Spintend.
The CAN port shouldn’t matter and I guess both controllers are already connected via CAN-Bus internally, so connecting with one cable should be fine. You can check if data from both sides are logged when opening a log, tab on the little arrow so you can choose what data is displayed and then tab on the split arrow to show individual data from both ESCs.
You could also go to Settings -> Magic -> Developer Mode and enable it. Then you can see the “VESC Count” that should show “2” in your case.
@ProfoundMagician I checked tracking for a few Metr Pro CAN orders to the US and it looks like they haven’t reached the US yet. The shipping company stated that packages to the US can take longer than normal at the moment because of Covid-19 related limited transport capacities.
what’s the largest memory size the metr can can support? 128GB? 256GB? I want to throw a big enough microsd card in it and forget about it, and maybe sync it up monthly if nothing happens during my ride.
A GPS “fix” is a successful geolocation. The first time a unit is used it can take a little longer to get a geolocation, this is true across many devices.
When the note is lost there is always the option to open the case and have a look at the pairing code inside.
Thats what I thought, just wasn’t sure cos of that photo
