Electronics Box

This rainproof box protects FarmBot's electronics from rain and debris. It features an easy-to-use tool-less double latch design for quickly opening and closing the box, a rubber gasket to keep moisture out, and a custom gland for all of FarmBot's cables to be passed through. The lid, latches, and box are made of UV stabilized materials.

Now pre-assembled

As of the v1.4 release the electronics box, push-buttons, LED indicators, and all internal electronics boards and wiring comes completely pre-assembled with all kits.

Farmduino

The Farmduino is an electronics board that combines the functionality of an Arduino MEGA 2560 microcontroller and a RAMPS shield. It features a board layout and connectors that are optimized for FarmBot. It receives G-code commands from the Raspberry Pi and then moves the motors, reads sensors, activate peripherals, and more.

Farmduino is open-source

Stepper Drivers

These drivers convert step and direction signals from the microcontroller into powerful electrical pulses sent to the NEMA 17 stepper motors to allow them to move. All of the stepper drivers have been pre-mounted and tested on Farmduino.

Trade Name

A4988 Stepper Motor Driver Carrier (Header Pins Soldered)

Microstepping

full-step, half-step, 1/4-step, 1/8-step, and 1/16-step

Output Current

1.5 A per phase without a heat sink or forced air flow (rated for up to 2.0 A per coil with sufficient additional cooling)

Protections

Over-temperature thermal shutdown, crossover-current protection, and under-voltage lockout, short-to-ground, and shorted-load

Adjustable?

Current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates

Soil Sensor PCB

The Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. The more water that is in the soil means the better the conductivity between the pads will be and will result in a lower resistance, and a higher SIG out.
