ESP32 Arduino CAN Wifi interface, logger, and development platform
Transmitter to multiple microDisplays and phone apps
Starting at $89 -order here-
(Read manual and confirm bus connection before order. Allow extra time--hand soldered to order.)
Safely transmit data without dangerously running CAN networks around vehicle
Feeds up to four microDisplays and their peripherals
High-speed data feed for apps like TesLax - no need for an OBD bluetooth adapter!
Logging to MicroSD card
Pass-through CAN plug and play under Tesla seat with orginal connectors
OBDII and DB9 conniptions also supported
Switched 12v and CAN output for other tools
Hardware transmit disabled2 for confidence that will not interfere with existing network
Standard Arduino-compatible ESP32 module for fast, powerful customization with wifi and bluetooth
Pre-programmed to serve microDisplays - all smarts are on the server
Custom configuration and messaging through web page interface
Code on GitHub
Can run multiple servers simultaneously (one on each CAN bus)
Three versions:
Model 3/Y Chassis Bus - plug and play under seat
OBD CAN/Powertrain bus - requires purchase of OBD Y cable to be installed behind center console.
Generic with DB9 CAN connector and external 12v supply
Popular signals and which bus they are on are documented here.
Example base configuration:
- One OBD powertrain CANserver plus one microDisplay - view one parameter on your dash - $150
My configuration: $433
OBD powertrain CANserver
Chassis CANserver
three microdisplays (battery power, motor torque, speed/blindspot)
two bargraphs (power and torque, or front vs rear power)
Blind spot LEDs
Wireless CAN lab monitor:
- One generic DB9 CANserver, one microDisplay, two AlpaNumeric LED modules - view several parameters from your equipment - $TBD coming soon
CANserver Gen 2 coming soon:
- Supports optional second CAN bus, so can read all data at once and save to logs etc
- Nicer SD card slot, some more IO to tinker with, other fixes
