FAQ:

1.
Q: Communication fails or has errors?

→ A: Ensure 120Ω terminal resistors are installed on CANH/CANL ends; verify baud rate ≤1 Mbps.

2.
Q: Module overheats?

→ A: Check for bus shorts (CANH/CANL to GND/VCC); ensure power voltage ≤5.25V.

3.
Q: Sleep mode won't wake?

→ A: Toggle S pin (low→high) or activate bus communication.

4.
Q: Unstable long-distance communication?

→ A: Reduce baud rate (e.g., ≤500 kbps); use shielded twisted-pair cables.

5.
Q: Compatible with 3.3V microcontrollers?

→ A: Yes, TXD/RXD logic levels support 3.3V/5V inputs.
