Bmini All-in-one

The All-in-one BMini shield is an advanced expansion board designed specifically for Arduino. It lets you create an independent and intelligent unit that controls motors, reads temperature probes, dims LEDs, manages 24VDC digital inputs. Feel free to connect as many BMini shields as you want in a network of intelligent devices (but not only BMini shields) that can easily communicate through RS485 bus (modbus protocol) or Ethernet (socket converter included).

This expansion shield is compatible with the small sized Arduino Mini 05, Uno and Ethernet. If you already know how to program an Arduino, you have done. You don't need to learn new things, the syntax is the same.

This shield has been designed specifically for home and industrial applications and environments. It helps you to automate every day task and make life easier. Check our wiki for details, code examples and libraries and success stories.

How it works: Program your Arduino Mini/Uno/Ethernet, plug it in the shield and power the board. That's it.

The Arduino board is not included in the package, it is sold separately.

More details

24V DC or AC
Separated power inputs for the Arduino board and for the digital inputs. No electrical noise and current peaks will alter the Arduino board
2 fuses for the supply voltage
5V power output for external sensors
24V power supply with two different connector plug IN/OUT configuration. Connect the 24V to the first BMini (J3 connector) and use the J4 for powering the following BMini in the network

4 high quality relays (40.52): output 24VDC max 5A, 230V max 8A
4 fuses for relays
4 opto-isolated digital inputs
8 analog inputs (0-5V) (can act as digital inputs/outputs)
2 PWM outputs
I2C bus
4 LEDs for digital inputs status

Ethernet (using the socket converter included)
RS485 bus line (120-Ohm resistor included)
Maxim MAX 1487 transceiver
One LED for modbus status

Dimensions:

16.5x11 cm (6.4x4.3 in)
Easy to mount in home automation or industrial existing structures
