== Summary ==<br />
The 2-DOF Pan-Tilt HAT by Waveshare is a Raspberry Pi add-on board that controls two servos over I2C. It is suited for basic camera panning and tilting applications and ships with examples for both Raspberry Pi and Jetson Nano.<br />

== Notes and version constraints ==<br />
* Version-sensitive: the light sensor change from TSL2581FN to TSL25911FN (Rev2.1) may require software updates.<br />
* Test each servo's full rotation range separately before assembly to avoid jamming or overheating.<br />
* Jitter occurs when the target angle is below the servo's minimum physical step angle.<br />
* Seeing three I2C addresses during scan is expected: 0x40 (PCA9685), 0x70 (ALLCALLADR register), and 0x39 (light sensor).<br />
* Precise angular control is not achievable on this entry-level product.<br />
* bcm2835 demos are no longer recommended; prefer WiringPi and Python examples.<br />
* Bottle-based remote control supports Python 2 only.<br />
