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;

Very nice board

For CAN32 - An ESP32 dev. board with CAN-Bus (V2.1)

The shipping took a while but when it arrived I was impressed and pleased.

The notes say you have to remove the SDCard when programming but in practise I found this wasn't necessary.

The expansion connector is interesting and if it exposes an I2C interface or a UART I'd suggest adding a U-Blox SAM-M8Q daughter board as this would allow the construction of a very small CAN logger with GPS. Failing that, a battery backed RTC would be useful to add a timestamp to the logs.

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

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.

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!

Nice and clean

For Teensy 3.2/4.0/LC slim micro SD card adapter

Works very well with Teensy3.2. I use it to read and write files to sd card with the SdFat library (https://github.com/greiman/SdFat).

Dual CanBus Review

Works great, but MUST set txAlt and rxAlt for FlexCAN

Very nice board
