The Xadow Audio integrates a speaker box and a microphone on one single board. The speaker unit is rated at 0.7Watt with an impedance of 8 ohm. Unlike the common cone type speakers、the loudspeaker driver used on the Xadow Audio has a flat surface and is m

Features：One of the most frequently used parts in Makeblock platform、Compatible with most makeblock motion and Structure components.。Made from 6061 aluminum extrusion、anodized surface. Excellent strength and twist resistance.。With holes on 16mm increments、can be drilled for 4mm hardware.。Threaded slot enables easy and flexible connection.。Cross-sectional area 8x8mm.。Total number of beams is 10.。Note：。We changed the version of Beam0808、the new version Beams are 8mm shorter than the old version Beams.。Part List：2x Beam 0808-80。2x Beam 0808-128。2x Beam 0808-144。2x Beam 0808-160。2x Beam 0808-192

。A big sister to our EL tape、the EL panel is a similar item that comes in a 10 cm square format. You'll notice when working with it that it shares some of the same features as the EL tape：flexibility、portability、and a beautiful soft glow. It can be used as backlight for an illuminated device、or a platform for paper-cutting artwork. Post it on a flat surface or wrap it around a curved surface. Use it in a project as a lighting element or attach it to a shirt. The options are amazing.。You need an inverter to drive the EL light、to control it、please pick up an EL Shield.。Features。No heat loss。Great backlight material。High efficiency(97%)。Does not emit UV light。Soft light that is not harsh on the eyes。Waterproof、except the connecter。The higher voltage EL USB inverter is recommended because it produces a stronger light。Able to be cut into other shape。Specifications。Dimension：10 cm×10 cm。Thickness：0.4 mm - 1.0 mm。Operating Voltage：100 V～ 220 V Optimum：120 V。Operating Frequency：50 Hz～ 5000 Hz Optimum：1500 Hz - 2000 Hz。Static Capacitance：6 nf/m(20 ° C、the RH <80%)。Brightness：30 cd/m2 ～ 126 cd/m2(at 120 V、200 Hz ～ 2000 Hz)。Power：108 mw m ～ 1032 mw/m(at 120 V、200 Hz ～ 2000 Hz)。Life：approximately 8000 hours。Operating Temperature/Humidity：-10 ℃ ～ + 60 ℃/RH < 90%。Storage Temperature/Humidity：-10 ℃ ～ + 60 ℃/RH < 65%
