Infarm Gateway User Manual

1.Introduction

The Infarm Gateway acts as the bridge between the internet and the onboard control systems of

the Acre and Instore farms.

The Infarm Gateway runs and maintains the following services:

● Link between Infarm BE and Farm

● Controls internet connectivity directly (cellular)

● Facilitates and manages local communications

● Runs business logic services (growing schedules, recipes, etc..)

● Provides local access to the Farm (over BLE)

● System updates (gateway services and controllers firmware)

● Logging services

22 PRG Programming port 23 power in micro-USB connector that allows flashing of the eMMC from a host computer using balenaEtcher (balena.io/etcher) or usbboot. If the device is powered via a cable connected to this port, it will enter a programming mode exposing its eMMC as mass-storage to a host computer (via balenaEtcher or usbboot). balenaFin can only be booted into flash mode via this port polarity is denoted on PCB silkscreen Barrel Jack power in 2.1 / 5.
