Driver - Ttl232r-3v3

TTL-232R-3V3 ESP32 Orange (TX) → RX (GPIO16, etc.) Yellow (RX) → TX (GPIO17) Black (GND) → GND Red (3.3V) → VIN (optional – if low power)

Offers direct DLL access for custom application development.

Red wire provides ~50-100mA max – enough for low-power chips, not motors or sensors. ttl232r-3v3 driver
