Good day. I am ready to complete your project. I work in Altium Designer. Write to me, we will discuss the details.

Доброго дня.
Замовлення має назву: "PCB розробка платки відео сканера". Але дивлюся на опис, то чомусь здається враження що не тільки РСВ плата потрібна, але ще й схема самого сканеру.
Я нічого не переплутав? Електрична схема є у наявності?
Якщо маєте схему, то далі можлива співпраця.

немає схеми нажаль 😔 но може буде
-
Як я вже писав, буде схема - буде результативне виконання.
Чекаємо на електричну схему.
