, hombre si tenemos tienda, son baratos ( el ARM9 = 30€ ) y son faciles de montar seran bien venidos
Overview
The VGX is a full-featured single board computer that brings together the latest in embedded technologies. Intel's RISC-based XScale PXA255 provides the forum for a powerful but low power consuming 400MHz, <500mW processor. It includes a Silicon in Motion graphics controller for the rich graphics without the heat. Its on-board I/O is as comprehensive as you can have on such a small, 4"x6.5" platform, and it includes 7 serial ports, Ethernet 10/100bT, USB host, dual CAN 2.0b and an AC '97 stereo Codec. The platform has been specially designed for both battery and external power supply types of application scenarios.

Digi-Key= 400MHZ=47$ que al cambio son = 47€ o el de 300MHZ a 35$
Solo le veo un incombeniente, que es jodido de soldar ( BGA )
PDF de caracteristicas
Hay que hacer lo que sea para incluirla ( sobre todo que sea facil el montaje, por que el BGA ya hace tiempo que lo descartamos pero esta no tiene 666 patillitas
) , con este micro conseguimos igualar a N64 y casi alcanzar a Dreamcast , ¿ no ?. Ademas nos ahorramos historias por que esta preparado para conectarlo en un televisor ( no hara falta DAC ¿no? ), ademas de poder conectar un diplay
Importante quiero que comenteis vuestras opiniones
