Add CAN-Bus capability to your project with this transceiver addon

The Teensy 3.6 is the first Teensy board to offer dual CAN-bus. This tiny backpack includes two SN65HVD230D transceivers, one for each CAN line. Also included are 120Ohm termination resistors. The un…

Excellent product, love the small size!

The only Teensy CAN adapter there is -- and the best! These little boards solder right on and give you dual (or single) CAN busses. Installation is easy and they work great. Integrated termination resistors make everything neat.

Remapping CAN0 is a bit of a pain, an example of setting it up with the FlexCAN library would be great to have on the page here.
Also note that leaving Rs floating will cause slightly strange behaviour. If it's pulled to positive, it is effectively in 'normal' mode where there is no speed limitation on the drive transistors; grounding it shuts off the drive transistors altogether but leaves the receiving hardware powered up; but doing neither of those allows the resistance between the pin and 3.3v to control the slope (effectively the output power) of the output drivers.
So basically just pull it to 3.3 unless you're doing something special.

Thank you for your review, Isaac!

Works great, but MUST set txAlt and rxAlt for FlexCAN

The Teensy 3.6 has two pairs of pins that can be used for CAN0: 3 & 4 or 29 & 30. The default is 3 & 4, but this adapter connects to the alternate pins 29 and 30. If you use the collin80/FlexCAN library, you have to set the alternate pins when you initialize the bus.

Can0.begin(250000, defaultMask, 1, 1);
Can1.begin();

The 1 and 1 above tell the library to use the alternate pins. 500000 is the baud rate. Can1 doesn't have alternate pins. It will start with the default baud rate and mask unless otherwise specified.

You will also have to define defaultMask at the top of the sketch:

static struct CAN_filter_t defaultMask;

Shipping time 5 weeks, no response on emails

For professional company's buying here won't be a good choice.
First order had to wait 5 weeks so we already had to buy alternative product.

Second time before ordering contacted seller, asked how many on stock, seller promised to to send immediately after payment.
After payment no reply to emails anymore. No tracking nr or whatsoever.
No idea if and when we will receive goods.
Shipping cost are high (€24,-) so you would assume it's quick right, but after 9 days still nothing.

complete lack of basic communication

Asked a very short question which would need a quick answer, and nothing. No documentation on how to install, just unclear images.

Davide | Jan. 23, 2019

No support is given, lack of communication

Beside having quickly answered to the request for an additional item (that by inadvertence was not delivered and required a Paypal claim to do so), the seller is not answering requests for information about the product (i.e. Will any Teensy 3.6 GND and 3,3V able to provide sufficient current to the module?) and to provide a correct invoice.

is there a diagram how to connect it ?

I have got the dual can-bus on teensy and everything is soldiered, i have been trying to make it work using the recommended library but still no luck!!,
is there a way to show how to connect it ? i Tried using CAN0 and CAN1 and the alternativeCAN0.

is there way that shows how to get it done and how to make it work please that will be so helpful.

Thanks in advance

Hi Mohammed,

Please contact me via the “Ask a question button” on the product page.
Also one of the pictures on that page shows a connection diagram. Please make sure to connect CAN-H, CAN-L and ground as well.

Cheers,
Paul

Amazing piece of kit. Very good support.

Very good implementation and design. Fits perfectly on top of Teensy 3.6. Perfect for race car dash and works perfectly with LinkG4+ ECU

Review for Dual CAN-Bus adapter for Teensy 3.5, 3.6

I have not yet tested it functionally but here are a few comments nonetheless:

A pdf detailing header soldering, etc would be helpful.

A jumpered or removable 120 ohm termination resistor would be nice.

Response from Fusion Tech | Feb. 13, 2018

Hi!
Header soldering is fairly simple, just line up with the bottom of the Teensy and solder in place (illustrations available on product page.
I have considered a jumper for the resistor, but space is very confined and most customers prefer to have the 120Ohm resistors soldered in place.

I appreciate your comment!

Best dual-CAN adapter out there.

Bought this for sniffing traffic on industrial CAN networks and some car hacking on the side. Can't get any smaller, and is a perfect fit on the Teensy 3.6.
The seller is in the Czech Republic, so if you are a US buyer like me, be patient. He shipped my order off very quickly, but our wonderful USPS made sure to add the delays in. Nothing at all to do with the seller.
Arrived, soldered up, and worked perfectly on the first try using an example sketch from the recommend library. The dual CAN is already proving very useful - I was logging frames from two buses running at two different baud rates, simultaneously.
My only regret at this point is not buying several of these. The Teensy plus CAN is a great combination, especially if you plan to get creative with your vehicle bus.
