Kutentha mbale ndi Kuzirala Solutions
SBC-IOT-iMX8 imaperekedwa ndi msonkhano wosankha kutentha kwa mbale. Chipinda chotenthetsera chimapangidwa kuti chizigwira ntchito ngati chotenthetsera ndipo nthawi zambiri chimayenera kugwiritsidwa ntchito limodzi ndi choyatsira kutentha kapena njira yoziziritsira kunja. Njira yothetsera kuziziritsa iyenera kuperekedwa kuti zitsimikizire kuti pazovuta kwambiri kutentha kwa malo aliwonse amtundu wa kutentha kumasungidwa molingana ndi kutentha kwa SBC-IOT-iMX8. Njira zosiyanasiyana zoyendetsera kutentha zingagwiritsidwe ntchito, kuphatikizapo njira zochepetsera kutentha komanso zopanda pake.
