The LILYGO T-2CAN board is criticized for potentially requiring separate firmware libraries for its two CAN controllers and lacking CAN-FD support, which is becoming standard. A power-related concern is the absence of an ADC for measuring incoming voltage, crucial for automotive applications to mana

Pros
  • • Affordable price at $32.98
  • • Dual isolated CAN bus interfaces
  • • Qwiic connectors for expansion
  • • Software support for Arduino IDE and PlatformIO
  • • Upgraded with more powerful ESP32-S3 MCU
Cons
  • • Does not support CAN-FD
  • • Lacks ADC for measuring incoming voltage (critical for automotive sleep mode)
  • • Lacks ADC for measuring incoming voltage for automotive applications
  • • Requires separate firmware libraries for different CAN controllers
  • • Requires separate libraries for different CAN controllers
  • • Uses older CAN V2.0B protocol, not CAN-FD

The initial design of the case is a good starting point for users of the LilyGo T-2CAN, but it could benefit from improved thermal design to ensure proper cooling of the ESP chip.

Cons
  • • Lacks adequate ventilation for the ESP chip
