Re: UTComp or Display failure after 12V to ACC +5V OUT(B6)

It looks fine. R17 is not placed from factory. This small cap between pads is also mod from factory.
You can send unit and display for checking, we will see

Re: Pamięć EEPROM 25LC640 różne odczyty

Często pamięć w układzie jest zalakierowana, po wylutowaniu zostaje cienka warstwa lakieru czy nawet kalafonii która działa jak izolator i albo oporność pinów rośnie (niestabilny odczyt) albo w ogóle nie czyta (brak komunikacji). Oczyść dokładnie piny pamięci izopropanolem lub rozpuszczalnikiem nitr...

Re: UTComp or Display failure after 12V to ACC +5V OUT(B6)

Seems like module is fine and I worry that oled panel may be damaged or DC/DC converter on display board. The easiest way to find out is to connect second display to module. You can send to us module (without disassembling oled screen until we will know what is damaged) and we can check it with othe...

Re: UTComp or Display failure after 12V to ACC +5V OUT(B6)

4,8V for oil pressure sensor is fine (4.5V and above is fine). Connecting +12V to +5V output may damage module and display. When you connected +12V to +5V rail, you had also +12V on all +5V outputs on UTCOMP. From +5V outputs are powered sensors, buzzer, keyboard and display. Which display do you ha...

Re: Nissan Patrol Y60

Można, ale musi to być jeden sygnał (jeden przepływomierz różnicowy: zasilanie paliwa minus powrót do baku)

Re: Nissan Patrol Y60

Cześć, zużycie paliwa nie będzie działać, ale to co wymieniłeś + sygnał prędkości czy rpm zawsze można podłączyć (jak nie będzie sygnału w aucie to również na dodatkowych czujnikach). Odezwij się do Jacka z Motoorion (https://www.facebook.com/motoorion4x4/) z tego co wiem już kilka patroli przerobił...

Re: Trying to read 25WP080 not working

Changing fw does not have influence on programming FLASH, but when it's in external circuit and is communicating with uC everything is possible (changed firmware may change communication with flash). Do you have possibility to desolder the chip and try in adapter? You can also try to increase voltag...
