The Raspberry Pi runs a custom operating system named FarmBot OS, allowing FarmBot to:
- Communicate with the web application over WiFi or ethernet so that it can synchronize (download) sequences, regimens, farm designs, events, and more; upload logs and sensor data; and accept real-time commands.
- Communicate with the Farmduino to send G and F commands and receive sensor and encoder data.
- Take photos with a USB or Raspberry Pi camera, and upload the photos to the web application.
- Get configured over WiFi, mitigating the need to plug in a mouse, keyboard, or screen.
Using a desktop computer or laptop, go to os.farm.bot to download the latest FarmBot OS
.img file according to your FarmBot kit and it’s internal computer.
To write FarmBot OS onto the microSD card, you must use a special
.img writing tool. We recommend downloading and installing Raspberry Pi Imager for this purpose.
Drag and drop will not work
Using your computer’s default file browser to drag and drop or copy and paste the FarmBot OS
.img file onto the microSD card will not work. You must use a special writing tool as described above.
Once you have Raspberry Pi Imager installed, connect the microSD card to your computer using a card reader. You may need to use the microSD card to SD card adapter included with your kit.
Open up the Raspberry Pi Imager program and click
CHOOSE OS. Then scroll to the bottom of the popup and select Use custom Select a custom .img file from your computer. Then select the FarmBot OS
.img file you downloaded in Step 1.
CHOOSE STORAGE button and then select the microSD card (it should show up as a
7.9 GB option).
Do not use large capacity microSD cards
FarmBot OS will not work with microSD cards larger than 32GB in capacity. Please use the microSD card provided with your FarmBot kit.
WRITE. Your computer may ask you for permision to perform this action. Once permission is granted, Raspberry Pi Imager will write FarmBot OS to the microSD card and then verify the installation. The process will take approximately 1 minute.
After completing, you may remove the microSD card from your computer and close Raspberry Pi Imager.
Insert the microSD card into the Raspberry Pi. The card slot location will differ depending on the FarmBot kit you have.
For Genesis kits, the card slot is located on the back side of the Raspberry Pi, on the right-hand edge. You do not need to remove the Raspberry Pi from the electronics box to insert the card; we have left enough access room.
For Express kits, the card slot is located on the front side of the Raspberry Pi, on the left-hand edge.
Plug your FarmBot’s power supply into a wall outlet. You should now see a solid red LED and a steadily flashing green LED on the Raspberry Pi, indicating that the Pi has adequate power and is busy booting up. Refer to the status LEDs page for more information, especially if your LEDs are not lit up as described above.
