LCD Keypad Shield LCD1602 Compatible Arduino con pantalla y botones integrados

El shield està construït amb PCB de fibra de vidre (FR4), components electrònics estàndard i un mòdul LCD amb controlador compatible HD44780. Les dimensions típiques són 80 mm x 58 mm x 23 mm, i el pes ronda els 42 g. El paquet generalment només inclou el shield muntat, sense cables ni documentació física; es recomana verificar si el venedor afegeix manual o accessoris addicionals.

El LCD i el shield estan dissenyats per funcionar a 5 V±0,25 V, amb un consum típic inferior a 50 mA amb el backlight encès. Operen de manera fiable entre 0 °C i 50 °C i RH < 80% (sense condensació). Tensions per sobre de 5,5 V poden danyar irreversiblement el controlador o el backlight LED, per la qual cosa es recomana fer servir sempre fonts d’alimentació regulades.

L’ajust del contrast es fa mitjançant un potenciòmetre present al mateix shield, cosa que permet adaptar-lo a diferents angles de visió o condicions de llum. La retroil·luminació es pot activar/desactivar programàticament o amb un jumper segons la versió. No requereix manteniment periòdic; tanmateix, es recomana evitar ambients humits o amb excés de pols i netejar suaument la pantalla si cal.

The shield is built with FR4 fibreglass PCB, standard electronic components and an LCD module with a compatible HD44780 controller. Typical dimensions are 80 mm x 58 mm x 23 mm, and the weight is around 42 g. The package generally includes only the assembled shield, without cables or printed documentation; please check whether the seller adds a manual or extra accessories.

The LCD and shield are designed to operate at 5 V±0.25 V, with typical consumption of less than 50 mA with the backlight on. They operate reliably between 0 °C and 50 °C and RH < 80% (non-condensing). Voltages above 5.5 V can irreversibly damage the controller or the LED backlight, so regulated power supplies should always be used.

Contrast is adjusted using a potentiometer on the shield itself, allowing it to be adapted to different viewing angles or lighting conditions. The backlight can be switched on/off programmatically or via a jumper, depending on the version. No periodic maintenance is required; however, it is recommended to avoid damp or excessively dusty environments and to clean the screen gently if needed.
