vakВот такое чудо мне вчера принесли поиграться.
Процессор Ralink RT3050 (MIPS 24KEc) с частотой 320 МГц и памятью 32 Мб. Два порта Ethernet, один порт USB и консоль RS-232. Внутри Linux 3.3.8 (OpenWRT). В файловой системе 15 Мбайт свободного места. Есть драйверы и примеры работы с сигналами GPIO, SPI, I2C.
Сделано в Литве фирмой 8devices. Процессорный модуль предлагается за 22.00€, вместе с отладочной платой и корпусом - 49.00€. На сайте есть исходные тексты и подробные инструкции по сборке.
Обнаружился обзор на английском, откуда я немедленно попер фотки.
Вот протокол загрузки системы, со всеми техническими подробностями.
