OP-1 Hardware

NOTE: This document is incomplete.

Overview

The OP-1 is made up of the following parts:

  • Aluminium Chassis
  • Speaker
  • UI Board
  • Display
  • DSP Board
  • Battery
  • IO Board
  • Keyboard
  • Ribbon cable (connects all PCB:s together)

Display

The display size is listed as 320x160 pixels. In reality it's a lot bigger vertically as part of it is hidden under the keyboard. The actual size is 320x240. In addition to this mismatch the actual visible portion of the display is actually closer to 150px high.

  • Part Number: 74-X000045
  • Width: 68mm
  • Height: 49mm
  • Resolution: 320x240 px
  • Usable resolution: ~ 320x150 px

Battery

The OP-1 battery is a 3.7V li-polymer battery rated at 1800 mAh.

The model number is 055070 and the connector type is probably a JST ACH. Source: operator-1.com The connector on the PCB looks like BM02B-ACHSS-GAN-TF(LF)(SN) and the connector on the battery looks like ACHR-02V-S.

TODO: Verify connector type and exact part number.

DSP Board

  • Main processor: ADSP-BF524C2
