pd: he estado buscando para ver si es programable por el puerto usb trasero, con alguna tool pero no encuentro ni en la web de conceptronic ni en la de via del chip,de todas formas si alguien me puede sacar de dudas, estaría bien, ya que las pics y otras placas programables compatibles escasean por no decir que no tienen existencias en las tiendas.
