Functions & design specifications

Independent development

The design covers scheduled dry-food dispensing and a tag-controlled bowl lid, using independent tags, App and cloud services. Public function reference: PETLIBRO One / PLAF301, ASIN B0FP2LV1KJ.

US version design specifications

Design inputs: 3 L hopper, 2–15 mm dry food, up to 10 daily meals, dual-band Wi-Fi, one bound tag and three D backup cells. Procurement documents cover a US version and 1,000 units; batteries are supplied separately.

The visualization package includes component model mappings, dimensions, model sources and editable KiCad files.

Board architecture & editable CAD

Main controller and peripherals

ESP32-C5-WROOM-1-N8R2 provides dual-band wireless control. TCA9535 expands I/O, ADS1015 reads analog signals, PCF85063 provides the RTC interface, and MAX98357A drives an 8-ohm BTL speaker. The OLED interface uses 3.3 V I2C.

Editable circuit and board files

Main-board v0.3 and reader v0.2 packages include schematics, PCB layout, local libraries, net maps and native CAD reports. Download the source files to inspect the electrical connections and board geometry.

Power, backup & cable budget

Protected power path

TPS259470 protects the USB input. TPS2116 selects USB or three series D cells; TPS63021 generates the 3.3 V buck-boost rail and TPS610333 supplies the RF rail. The circuit includes reverse-battery protection and battery-voltage sensing. Backup cells are not charged by the board.

Adapter and cable specifications

The selection documents specify Phihong PSAA05A-050QL6W-R, 5 V/1 A, for the US version. The 1 m cable specification limits the complete VBUS/GND loop including contacts to 0.20 ohm at 0/25/45 C and defines a 20 AWG alternative.

Dispensing, lid drive & protection

Two geared motors and Hall feedback

DRV8833 provides two motor channels. The selected NFP-GM12-N20R specification uses a 6 V A12 winding, 100:1 dispensing gearing and 210:1 lid gearing. The circuit motor supply follows VSYS at approximately 3–5.25 V. DRV5033 Hall pulses provide rotor feedback for portion calibration.

Independent hardware permission

Directional AND gates use endpoint CLEAR signals to limit MCU motion requests. Pinch and wiring-health signals remove hardware permission; the pinch path latches motion off. Endpoint gating operates independently of firmware polarity settings.

Four sensor states & corrected polarity

Two-wire resistance coding

The remote circuit uses 5.6 kohm in series with 10 kohm shunted by a normally open reed, with a 10 kohm host pull-up. At nominal 3.3 V, RAW_A/B ideal voltages are 1.185/2.011 V. Short and disconnected states remove global wiring-health permission.

RAW_B triggers endpoints and abnormal states

OPEN/CLOSED endpoints, PINCH and low-food events use RAW_B: open reed, 15.6 kohm and CLEAR low. Normal/non-endpoint state uses RAW_A: closed reed, 5.6 kohm and CLEAR high. Sensor placement and magnetic bias follow this action polarity.

State	Contact / remote resistance	Ideal V @3.3V	WIRING_HEALTH_N	CLEAR	Meaning
RAW_A	Closed / 5.6 kohm	1.185	1	1	Normal / not endpoint
RAW_B	Open / 15.6 kohm	2.011	1	0	Endpoint / pinch / low food
SHORT	0 ohm	0	0	1	Global motion permission removed
OPEN_CIRCUIT	Disconnected	3.3	0	0	Global motion permission removed

Tag identity, RF tuning & access

Own authenticated credential

The reader uses ST25R100-CMET, a 27.12 MHz crystal and a PCB coil. The tag selection is Identiv LA1PADNX9025 / NTAG224 DNA. The credential design defines personalized keys, binding, revocation and replacement for independent tags.

Reader placement and RF tuning

Reader documents define coil and matching values, reset control, logic/RF supply rails and SPI signals. The sample plan covers the metal bowl, enclosure, collar orientation, adjacent tags and adjacent feeders.

Firmware, persistence & recovery

Runtime source v0.5

Source includes the control core, BSP, runtime and a two-zone Flash journal. Checkpoints and unacknowledged events are copied to an inactive zone and read back before commit. Reclamation is restricted to stopped USB-idle windows and cancels on requests or faults. The download includes diagnostic build settings.

Persistence and build resources

The firmware package includes persistence code, control contracts, build instructions, diagnostic images and model execution records. Version-specific Flash format and migration behavior are documented with the source.

App, cloud & offline behavior

Local and remote function design

The application design specifies local schedules, authenticated requests, operation IDs, duplicate protection and event acknowledgments. Offline and reconnection contracts define local operation and event upload without repeating a feed.

Own App and services

The App/cloud scope covers provisioning, pet and tag binding, accounts, meals and portions, logs, notifications, credential replacement and signed OTA. Interface contracts and software development notes are included in the resource downloads.

Connectors & harnesses

Eleven controlled harnesses

Battery, reader, two motors, speaker, Hall feedback, four sensors and OLED use 11 harnesses and 33 main-board pins. The harness documents list 54 JST PH contacts per unit, wire lengths, gauges, crimp requirements, strain relief and retention.

Wire by signal labels

Ten-pin SPI separates 3.3 V logic, 5 V RF and ground returns. OLED SDA/SCL order differs from the host connector and follows the pin map. Both BTL speaker terminals remain isolated from ground.
