FED3 is a homecage pellet-dispensing device for training mice on operant tasks. Mice interact with FED3 through two nose-pokes and FED3 responds with visual stimuli, auditory stimuli, and by dispensing pellets. All behavioral events are logged to an on-board microSD card. Click on the link to watch an introductory video.

FED3 is compact and wire-free so it can be placed in the homecage or mounted to the side with magnets. Its rechargeable battery lasts about a week between charges. The top lid is transparent to monitor the amount of available pellets. FED3 is open-source and fully programmable with the FED Arduino library which includes more than 10 pre-programmed feeding and stimulation paradigms.

Features:

• Two nose pokes, 8 RGBW LEDs on the front panel, 1 RGBW LED inside each poke, onboard speaker and pellet-retrieval sensor at the well.

• Hopper with capacity for 800 20 mg pellets with single-pellet dispenser and jam-clearance mechanisms.

• Built-in screen used to provide real-time feedback to the experimenter.

• Audio 3.5mm mono jack digital port programmable as input or output (3.3V logic) to synchronize with and control external equipment such as lasers or brain recording systems. You can get an audio-to-BNC adapter in our store.

What’s new in FED3.2:

• USB connector upgraded to the latest USB-C type.

• Single USB port for both charging + programming.

• Standard I2C connector for environment sensors (temperature & humidity). You can get the sensor and the cable for it in our store.

• Improved battery management and 4× faster charging.

SKU: OEPS-0430

Temperature and humidity sensor for the FED3.2 (*).

When this sensor is connected to a FED3.2 via the STEMMA QT bus, the FED3.2 can log the environment’s temperature and humidity to the SD Card.

Typical accuracy:

• Temperature: +-0.3ºC

• Humidity: +-2%

(*) It can also be used with any Arduino via a standard I2C connection.

Package includes:

• 1x Temperature and Humidity Sensor - AHT20

This peripheral requires additional components to operate. Please check the device connectivity list to purchase any cables, tethers and power supplies you might need.

New features in FED3.1, our enhanced version of the popular FED3 (yellow arrows in pictures):

• Two extra LEDs (RGBW) inside the pokes, that can be used for animal cues.

• Audio instead of BNC connector. This connector is smaller, and cables are more flexible, reducing the space taken up by the FED. You can get an audio-to-BNC adapter here.

• New, handy location of the battery connector, to make it easier to replace the rechargeable internal battery.

Package contains:

• 1x Assembled FED3.1, quality-tested and programmed to your time-zone.
