Teensy 3.2 based CAN controller/vcu [SOLD]

[jon volk]

Unlike Damien, I don’t have ambitions of retiring to Lanzarote, but looking to put a small dent in the cost of having to replace my drive unit. I put together a small and simple board that can function as a minimal add on CAN VCU. Board requires a Teensy 3.2 and has a CAN transceiver, 3 analog inputs, and 3 ground switched outputs. Boards will come fully soldered along with the required mating Molex connector and terminals.

Since it runs a 3.2, one could also port Tom’s BMS code over if you were looking for something in a sealed enclosure. I don’t utilize all the same inputs and outputs so those would need to be reassigned if you were looking to go that route.

I have some basic code up on GitHub for running LDU parameters over CAN in repo LDU_CAN https://github.com/jonvolk . Some use cases for analog ins would be throttle and brake pressure in order to do some preliminary processing in the Teensy and controlling those inputs to the inverter over CAN or use the outputs for driving analog gauges, water pump or fan relays, etc.

I have 4 boards immediately available, but will probably keep 1 for my own use.

Nice work!

How do you like the Cinch enclosure?

Theyre awesome, especially for the price. I prefer the MX-ME version with the Molex connectors since the threaded connections of the other style kind of suck.

Cool! I might give Cinch a try. I only worked once building a PCB for such enclosures, and I tried the Deutsch one. It was a nice one too. It ended up costing $40-50ish for both parts (excluding the one or two connectors you have to build to connect to it).

Ive actually got two Deutsch enclosures coming for a future project. Mainly because they’re clear and looked cool....and 90% of my connectors are Deutsch

Tempting... is that including case-ing etc?

[jon volk]

Yup, complete with cinch enclosure, connector and terminals.

I’m using one of these for CAN messages to my dash cluster (tach and inverter temp), and to transmit to my DC2DC. Also using spare outputs for fuel gauge stepper motor. Works great and neat solution.

Hi Jon. Do you have any units left to sell? I need one for my Boxster Tesla conversion.
