I found this STM reasonably low cost device with CAN capability. It still needs the CAN physical interface
https://www.bananarobotics.com/shop/Robotis-OpenCM-9.04-A-Microcontroller-(Bare-Bones)
Physical CAN interface found below for under $8. That's the same chip used on Frankenso.
http://www.ebay.com/itm/SN65HVD230-CAN-Network-Transceiver-Evaluation-Development-Module-Kit-TJA1050-/171538514567
Between both of these that's STM to CAN for under $20, and basically no soldering. Hmmm from the manual posted here http://www.robotis.com/download/doc/controller/OpenCM9.04_en/OpenCM9.04_manual_en.zip it appears the CAN board doesn't have a matching pin out, so it would need some little jumpers to change the pin out.
Are there any other low cost STM CAN capable boards out there?

Re: STM low cost CAN
No soldering and includes CAN with Automotive friendly power supply https://www.olimex.com/Products/Duino/STM32/OLIMEXINO-STM32/open-source-hardware No need for programmer, just a USB cable if you need to update the firmware. Costs about $25usd.

Re: STM low cost CAN
The board has arrived. The bare bones ChibiOS F1 project is https://svn.code.sf.net/p/rusefi/code/branches/rusefi_f1/ and got it flashed into the board using SWD from stm32f4discoveryrussian wrote:STM32F103C8T6 ARM STM32 Minimum System Development Board Module $4.74

Re: STM low cost CAN
this chip could be used for a thermocouple project, i guess.

Re: STM low cost CAN
i'd prefer ads1118 rather than max chips. probably the board will require power supply ic as well (lm7805 should be enough)
