When writing your initialization firmware, program a 10ms delay after pulling the EN pin high. This allows the internal LDO voltage rail to stabilize perfectly before enabling high-power output stages.

Check VCC voltage with a multimeter and verify that the Chip Select (CS) pin is driven low during transmission. Symptom: Intermittent data corruption or erratic behavior.
Wire the GND pin directly to the host microcontroller ground plane to prevent floating signals.
