7. Backlight LED wutar lantarki kewaye: SOT23-6LED direba guntu samfurin.Wutar wutar lantarki ta DC/DC zuwa LED da kanta tana samar da madauki, kuma an haɗa ƙasan DC/DC zuwa ƙasan 3.3V LOD.Tun da tashar tashar tashar PWM2 ta kasance ta musamman, tana fitar da siginar PWM na 600K, kuma an ƙara RC don amfani da fitowar PWM azaman sarrafa ON/KASHE.
8. Ƙimar shigar da wutar lantarki: an tsara matakan saukar da DC / DC guda biyu.Lura cewa masu adawa da R13 da R17 a cikin da'irar DC/DC ba za a iya tsallake su ba.Kwayoyin DC/DC guda biyu suna goyan bayan shigarwar 18V, wanda ya dace da samar da wutar lantarki na waje.
9. USB TYPE C debug port: TYPE C za a iya toshe shi kuma a cire shi gaba da baya.Saka gaba yana sadarwa tare da guntu WIFI ESP32-C don tsara guntun WIFI;juyawa baya yana sadarwa tare da XR21V1410IL16 don tsara T5L.TYPE C yana goyan bayan samar da wutar lantarki 5V.
10. Parallel port Communication: T5L OS core yana da tashar jiragen ruwa na IO masu yawa kyauta, kuma ana iya tsara sadarwa ta parallel port 16bit.Haɗe da ka'idar tashar tashar jiragen ruwa ta ST ARM FMC, tana goyan bayan karantawa da rubutu tare.
11. LCM RGB high-gudun dubawa zane: T5L RGB fitarwa an haɗa kai tsaye zuwa LCM RGB, kuma buffer juriya da aka kara a tsakiyar don rage LCM ruwa ripple tsangwama.Lokacin yin wayoyi, rage tsayin haɗin haɗin haɗin RGB, musamman siginar PCLK, kuma ƙara abubuwan gwajin RGB PCLK, HS, VS, DE;an haɗa tashar tashar SPI na allon zuwa tashar P2.4 ~ P2.7 na T5L, wanda ya dace da zayyana direban allo.Fitar da wuraren gwajin RST, nCS, SDA, SCI don sauƙaƙe haɓakar software mai tushe.
