ATECC608: usoro nchekwa maka Raspberry Pi

na Ọrụ IoT Ha na-ewu ewu n'etiti ndị na-eme egwuregwu na ndị ọkachamara dabere na bọọdụ mmepe dị ka Arduino ma ọ bụ nke ha SBC Utu Pi. Nchebe na oru ndị a bụ isi, ebe enwere ike ibuso ha agha ma ọ bụ gbanwee ọrụ ha ma ọ bụrụ na enwere nsogbu. Nke ahụ bụ nchegbu ATECC608 na-abịa iji dozie.

Ruo ugbu a, e nwere ọtụtụ modul na ihe dị iche iche iji mepụta ọrụ nke ụdị ọ bụla, mana ole na ole gbadoro ụkwụ iji mee ka nchebe ruo mgbe mmewere nke a ụlọ ọrụ Microchip, onye ama ama ama ama nke ngwaahịa dika PIC microcontrollers ya.
