Metal gears and 2.2 kg·cm of torque, 500–2500 us mapping to 0–180°. Drives page 45, where pulse width, travel and frequency are configurable. ★ Power it from its own 5V rail, sharing only ground.
⚠ Before you use it
Signal goes to GPIO16 (page 45 Servo). Power it from its own 5V rail, sharing only ground — 3V3 browns out and reboots the board. Set the pulse range for a new model first, or it may drive into a mechanical stop and strip its gears.
