Temp Range: -40C to 85C
Humidity RangeRH, =-3% from 20-80%
Pressure Range: 30,000Pa to 110,000Pa, relative accuracy of 12Pa, absolute accuracy of 100Pa

ATENTIE!
Conf. datasheet tensiunea maxima de lucru este de 3.3 3.6V valabil si pe pinii de comunicatie I2C.
Daca acest modul se conecteaza la Arduino ... cat si la alte dispozitive ce tensiunea nivelului logic este mai mare de 3.3V mai precis 5V este necesar acest convertor
Am si asa ceva si costa 10 lei
Daca nu se respecta interconectarea corecta privind nivelele de tensiuni logice NU OFER GARANTIE
Un efect de exemplu, daca conectam un modul ce are comunicatie de 3.3V la Arduino UNO ce are nivelul logic de 5V, RX (I2C dupa caz) din modulul de 3.3V se va arde si devine scurt fata de GND !!!
In acest caz modulul devine inutilizabil (5en50r al3x t3rm1)

Modul cu 4 relee alimentare 24V, contact 10A
Modul 4 relee cu optocuplor:
- Semnal TTL - Trigger LOW sau HIGH, selectabil - jumper
- Semnalul logic aplicat trebuie sa fie tip OPEN COLECTOR (fara pull up din microcontroler) altfel nu functioneaza mai ales cu nivele mici de semnal (datorita modului de constructie optocuplor de pe placa releelor)
- Izolare galvanica prin optocuplor
- Putere Maxima 2.5KW pentru (250AC - 10A)
Nota releul trebuie alimentat la tensiunea de lucru specificata 24V

Description:
L293D is a monolithic integrated, high voltage, high current, 4-channel driver.Basically this means using this chip you can use DC motors and power supplies of up to 36 Volts, that's some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what s known as a type of H-Bridge. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.
- 2 interface for 5V Servo connected to the high-resolution dedicated timer - no jitter!
- Can drive 4 DC motors or 2 stepper motors or 2 Servo
- Up to 4 bi-directional DC motors with individual 8-bit speed selection
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.
- 4 H-Bridges: per bridge provides 0.6A (1.2A peak current) with thermal protection, can run motors on 4.5V to 36V DC
- Pull down resistors keep motors disabled during power-up
- reset button
- 2 external terminal power interface, for separate logic motor supplies, d51v al3x
