About this Gig
Does your pet feeder skip meals during a power cut, jam, or dispense the wrong portion? Reliable feeding depends on the controller board more than the app.
I design pet feeder controller PCBs for smart cat, dog and fish feeders, from schematic to fabrication files.
Included:
- ESP32 Wi-Fi/BLE control with offline schedule and RTC backup
- Motor driver for auger, stepper or gear motor, with jam detection
- Load cell interface for weight-based portions
- Food-level sensor input and manual feed button
- Battery backup and low-voltage power design
- Hardware safeguard against motor runaway
- Schematic and layout in KiCad or Altium
- Gerber, BOM, pick-and-place, PDF schematic, 3D STEP
Optional: RFID pet ID, water pump driver, camera connector (Premium).
Low voltage designs only. Firmware, app, enclosure and certification are quoted separately.
Send your motor type, portion method, power source and enclosure size and I will confirm feasibility before you order.
FAQ
Which pets and feeder types do you design for?
Cat, dog and fish feeders, and small livestock feeders, using auger, stepper, gear motor or servo mechanisms.
Does the feeder keep working if Wi-Fi or power fails?
The board is designed for an offline schedule using a real-time clock. Standard and Premium add battery backup for power cuts. The behavior itself is set in firmware.
Can it measure portions by weight?
Yes, in Standard and Premium, using a load cell and 24-bit ADC. Accuracy depends heavily on the mechanical mounting of the load cell and on calibration.
Can it measure portions by weight?
Jam detection by motor current sensing and a hardware safeguard that cuts motor power if the MCU stops responding, so a firmware fault cannot keep dispensing food. The board is low voltage only.
Which software and files do you provide?
KiCad or Altium, EasyEDA on request. You receive Gerbers, drill files, BOM, pick-and-place file, PDF schematic and a 3D STEP model.
Can you redesign my existing feeder board?
Yes. Send your schematic or photos, your enclosure drawing and the problems you see. I review it and send a custom offer.
Do you provide firmware, an app or the enclosure?
No. Those are quoted separately. I design the hardware so firmware and mechanics can follow.
