This is a used Mettler Toledo circuit board with the board number 12122205-A printed on the PCB and a bar-code label reading 000012122200 0000 00. It carries a processor, on-board power supply circuits, a CR2032 backup cell, a piezo buzzer and several wire-to-board connectors. The instrument model it was removed from is not stated on the board.

What do the markings say?

Silkscreen: 12122205-A. Label: 000012122200 0000 00 and 0940 0935780027 CR0. The large square chip carries a sticker reading 1, 12121235B and 12121234B. The back of the board is marked FASTPCB, E300750, MDS 94V-0.

What is FASTPCB E300750?

FASTPCB is the marking of the bare-board fabricator, not the instrument maker. E300750 is printed next to it, and 94V-0 is the UL 94 flammability rating of the board material. These markings do not identify the instrument; the Mettler Toledo numbers are 12122205-A and 12122200.

What is on the board?

A quad flat package processor with a crystal next to it, Coilcraft power inductors, electrolytic capacitors, a piezo buzzer, a Maxell CR2032 3 V lithium coin cell in a holder, a 3-pin power connector and several multi-pin wire-to-board connectors.

What condition is it in?

Used, packed in an anti-static bag. The coin cell is the one shown in the photos and may need replacing.
