Pin-Tabelle6
| Pin | Signal / Name | Typ | Alternative Funktionen |
|---|---|---|---|
| 1 | GND | Ground | Ground Reference (0V) |
| 2 | ~OE | Digital | Output Enable (Active Low) — HIGH disables all PWM outputs; tie to GND for always-enabled |
| 3 | SCL | Digital | I2C Serial Clock (up to 1 MHz Fast-Mode Plus) |
| 4 | SDA | Digital | I2C Serial Data |
| 5 | VCC | Power | Logic Supply Voltage (3.0V to 5.5V DC) |
| 6 | V+ | Power | Servo / High-Power Rail (+5V to +6V DC, max 10A via terminal block) — powers servo motors; independent from VCC logic supply |
