Dalam isu ini, kami menolak kes sumber terbuka yang memenangi anugerah DWIN Developer Forum - Multi-function Weigher. Jurutera menggunakan skrin pintar COF 4-inci, dan melalui interaksi data antara teras T5L OS dan modul HX711 dan set sensor tekanan 5kg, pengguna boleh dengan mudah menyedari fungsi paparan pengiraan seperti berat, harga unit, jumlah harga, lalang, dll. ., serta fungsi mengira, menjejak lengkung perubahan berat, dan membetulkan ketepatan penimbang, dsb., supaya mudah untuk bertukar antara senario aplikasi yang berbeza untuk menikmati pengalaman penimbangan yang mudah dan cekap.
