Buying guide
Robot-eye electronics buying notes
This electronics add-on supports robot-eye control, wiring, or camera integration. It should be chosen together with the eye type, servo count, power plan, and available space inside the head.
- Match electronics to the motion plan before final assembly.
- Servo signal control and servo power should be planned separately.
- Camera modules need cable routing and rear cavity clearance.
Choose the right build path
| Build path | Best for | Choose when |
|---|---|---|
| Controller board | Servo-eye movement and coordinated robot-eye tests | You need ESP32-S3 and PCA9685-style servo control hardware. |
| Camera module | Camera-ready pupil builds and robot vision tests | The eye has a centered pupil opening and rear module clearance. |
| Wiring add-ons | Prototype assembly and clean routing | You need jumper wires or cable planning for servos and camera modules. |
Product questions
Does the controller board power all servos by itself?
Servo signal control and servo power should be planned separately. Size the power supply for the number of servos and the expected movement load.
Can electronics be added to a no-camera-hole eye?
Servo motion can be used with no-camera-hole eyes, but a hidden camera requires a camera-ready pupil opening planned before production.
Should I choose electronics before choosing the eye size?
Choose eye size and mechanical clearance first, then confirm controller, servo, camera, and wiring needs.
