4tronix have started building a range of Arduino compatible boards with our own brand of magic.

All 4 of the current members of this new range are fully compatible with Arduino Uno software, and the 2 larger Uno form factor boards are fully hardware compatible as well

In addition, the 4duino range features:

  • 16MHz ATMega328P-AU processors
  • 14 Digital I/O pins (5 of which can be PWM – Pulse Width Modulated)
  • 8 Analog input pins (6 of which can be Digital I/O as well)
  • Built-in 5V regulators (check individual specifications for current ratings)
  • Reset buttons
  • Full USB interface (using CH340 interface chip)
  • Micro-USB connector

The 4duino Uno full-size products also have:

  • DC Jack for powering via up to 11V
  • Coloured coded pins (Pro) or available holes for 3-pin sensors (GVS – Ground, Volts, Signal) for all 22 I/O pins

4duino Uno

IMG_1548d

This is software and hardware compatible with an Arduino Uno. You can use all the same addon Shields and get the same performance. In addition, we have made the extra 2 Analog pins available via the holes on the board into which you can solder headers if required.

These extra analog pins can be used within the Arduino IDE as A6 and A7. Note that they are analog ONLY – there is no ability to do a digital read or write on them and there is no ability to set pullup resistors.

Currently, the 4duino Uno is a depopulated 4duino Uno Pro board – so you can upgrade it to the full Pro specification with some surface mount soldering! Adding the GVS headers is much easier and a great upgrade though.

The USB interface is via the CH340 chip which has drivers available for all operating systems here.

On board 5V regulator: 1A

 

4duino Uno Pro

This is the fully populated version of the board that includes an integrated 2-channel H-bridge motor driver (the DRV8833).

The 4duino Uno Pro is fully hardware and software compatible with an Arduino Uno. You can use all the same addon Shields and get the same performance. In addition we have added colour-coded GVS headers for all the I/O pins including the additional 2 analog pins, A6 and A7. Note that these additional analog pins are analog ONLY – there is no ability to do a digital read or write on them and there is no ability to set pullup resistors.

The great news is that the Pro version also includes 2-channel full H-bridge motor driver so you can control motors without requiring any addition shields or messy wiring. In fact, with the GVS headers installed, together with the motor drivers, the 4duino Uno Pro is like combing an Uno, sensor shield and motor shield into a single board!

On board 5V regulator: 1A

Motor control Pins:

  • Motor 0:  D5, D9
  • Motor 1:  D6, D10

 

4duino Mini

IMG_1571a

The 4duino Mini is an extremely small version of the Arduino Uno with all the same I/O pins, USB interface, reset button and voltage regulator.

All 22 I/O pins are brought out to the board edge where you can connect directly to them or solder in the provided headers.

The extra 2 analog pins can be used within the Arduino IDE as A6 and A7. Note that they are analog ONLY – there is no ability to do a digital read or write on them and there is no ability to set pullup resistors.

It is intended that headers, if fitted, are fitted so that the underside of the board is visible during use. This side of the board has no components and so has more room for labelling of all the pins.

Certain pins have symbols around them:

  • Circle: this is a digital pin that is capable of PWM
  • Octagon:  These are the Ground connections
  • Square:  One of these is 5V and is either a 5V input to the board, or a 5V output if you are using the onboard 5V regulator. The other square is the VIN for the voltage regulator. This can be from 6V to 9V. So if you are using this board with 4xAA batteries you would have a 6V nominal voltage which you apply to the VIN and GND inputs. You can then use the 5V pin to power the rest of your ciruit (up to 150mA)

On board 5V voltage regulator:  150mA

  • Dimensions: 33.75 x 18.5 x 1mm
  • Weight: 2g

 

4duino Mini Pro

IMG_1678a

The 4duino Mini Pro is a slightly longer version of the 4duino Mini. The extra length is used to house the dual H-Bridge motor driver and associated components, as well as the power input and motor power outputs. The remained of the board is identical to the 4duino Mini

On board 5V voltage regulator:  500mA (peak)

  • Dimensions: 43.75 x 18.5 x 1mm
  • Weight: 2.6g

Motor control Pins:

  • Motor 2:  D5, D9 (labelled on PCB as M2, but is M0 to be consistent with 4duino Uno Pro)
  • Motor 1:  D6, D10
