Based on this work:

which is used to create a CAN bus interface between gas boilers, heat pumps etc., I have constructed a housing in which the ESP32 and the MCP2515 can be housed.
I have used an ESP32 with USB-C for this. The wiring is as follows.
INT > --
SCK > IO18 (CLK)
MOSI > I023 (MISO)
MISO > IO19 (MOSI)
CS > IO5 (CS)
GND > GND
VCC > VCC (5V)
To prevent the ESP32 from slipping back when the USB connector is plugged in, I inserted a 1.75mm piece of filament into the two holes. Should fit exactly.
There is also a reset opening and the two CAN-BUS terminals are labeled L (Low) and H (High).
The components can be found here:
