Hi, I am an assistant professor at Dept. of EE. I tough embedded system courses with Nucleo-64 F401 board. I want to use the newer evaluation board for the course which has a CAN controller. Is there a recommendation for it? Thanks

[Javier1]

do you need the builtin canbus transceiver also?

[JPARK.42]

If possible, it's the best option. However, I can use the external transceiver.

More important one is the budget which is less than 200$ / EA.

[Javier1]

200$is more than enough i believe.

I dont know any stm32 official board with builtin canbus transceiver. Maybe some ST employee should answer your question.

If i were the one choosing i would pick the latest version of their nucleo-64 f401 board and two of those cheap canbus transceivers.

The entire setup shoulnd cost more than 30$ per student (cheaper if you do big orders)

[JPARK.42]

Thanks for the quick response.​

One problem is that there is no built-in CAN controller in STM32F401xE (MCU of Nucleo-64 F401 board). That's why I am looking for the different evaluation board.

Try to have a look at https://www.st.com/en/evaluation-tools/b-g431b-esc1.html#documentation

1. Get some CAN analyzers.

• Seeed works and low cost (on Digikey): https://www.seeedstudio.com/USB-CAN-Analyzer-p-2888.html
• None of the CAN Analyzers I've used had a very nice UI, so...
• Recommend that first thing you do is program your Demo board to be a CAN Analyzer, outputting deciphered packets on UART and USB VCP, and allowing single char typing to trigger different CAN Tx packets (This is a useful project students can keep in their own toolkit, my EE work term students have done it).

2. We used NUCLEO-L476RG(STM32L476RG) for CAN experiments.

• We now have custom PCB with CAN using STM32L496, upgrade from L476
• We switched from STM32F4 to L4 series because the older F4 didn't have DE for RS-485
• The STM32L476RG-Discovery has lots more, but costs more.
• Check latest available demo boards (Digikey, Mouser...).

3. FYI

• I find it very useful to pair a breadboard with a Nucleo, and have students (and myself) wire & test circuits like CAN, USB VCP, etc. before ordering PCBs, even new EE's should still learn to breadboard, and pairing with a demo board means breadboard freedom, less flakey wiring, while still getting latest tech/MCU.
• Add some buttons and LEDs on breadboard just so they get a clue of real life circuits (Debounce, MCU pin current limits, etc.)
• And this set of ancient ref material is great for simple getting started (Engineer's Notebooks):

This is a very interesting board, i migth buy some

[JPARK.42]

Thanks for the information! This is a cheap and an interesting board! I will check it out.

[JPARK.42]

Good information! Prototyping is important technique to the engineer. I will check those boards also. I appreciate your help.
