WEO012864AL - Dies ist ein COG-Grafik-OLED-Module mit 2,42 Zoll in der Diagonalen, das aus 128 x 64 Punkten. Die Modulabmessung dieses Modells beträgt 60,5 × 37,0 mm bei einem 55,01 × 27,49 mm großen aktiven Bereich. Das OLED-Display ist mit dem IC SH1106 ausgestattet, der optional mit unterschiedlichen Schnittstellen bestückt werden kann; unterstützt die Schnittstellen 6800 / 8080 parallel, I2C und 4-adriges SPI.
Dieses monochrome 2,42-Zoll-128 x 64-Passivmatrix-OLED-Displaymodul zeichnet sich durch einen sehr breiten Betrachtungswinkel bis zu 160 ° aus. Die Logikversorgungsspannung liegt zwischen 1,65 V und 3,3 V, üblicher Wert bei 3 V, 1/64 Duty, ein Kontrastverhältnis von 10,000:1 (üblicher Wert). Die Betriebstemperatur dieser Modulserie liegt zwischen -40 °C und +80 °C; ihre Lagertemperatur liegt zwischen -40 °C und +85 °C.
Die organische Leuchtdiode (OLED) ist eine neuartige Technologie, die hellere und schärfere Bilder anzeigt und eine flexiblere Reaktionsgeschwindigkeit ermöglicht. Beim Modul handelt es sich um ein superflaches und leichtes COG-OLED-Display kleiner Größe mit geringem Stromverbrauch. Es eignet sich ausgezeichnet für Smart Home-Anwendungen, Medizinprodukte, in der Hand und am Körper tragbare Geräte.

| 15 | /CS | This pad is the chip select input. When /CS= “L”, then the chip select becomes active, and data/command I/O is enabled. | |||||||||||||||
| 16 | /RES | This is a reset signal input pad. When /RES is set to “L”, the settings are initialized. The reset operation is performed by the /RES signal level. | |||||||||||||||
| 17 | A0 | This is the Data/Command control pad that determines whether the data bits are data or a command. A0 = “H”: the inputs at D0 to D7 are treated as display data. A0 = “L”: the inputs at D0 to D7 are transferred to the command registers. In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. |

| 18 | /WR (R/W) |
This is a MPU interface input pad. When connected to an 8080 MPU, this is active LOW. This pad connects to the 8080 MPU/WR signal. The signals on the data bus are latched at the rising edge of the /WR signal. When connected to a 6800 Series MPU: This is the read/write control signal input terminal. When R/W= “H”: Read. When R/W= “L”: Write. |

| 19 | E/RD | This is a MPU interface input pad. When connected to an 8080 series MPU, it is active LOW. This pad is connected to the /RD signal of the 8080 series MPU, and the data bus is in an output status when this signal is “L”. When connected to a 6800 series MPU, this is active HIGH. This is used as an enable clock input of the 6800 series MPU. When /RD = “H”: Enable. When /RD = “L”: Disable. |

| 20~27 | D0~D7 | This is an 8-bit bi-directional data bus that connects to an 8-bit or 16-bit standard MPU data bus. When the serial interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SI). At this time, D2 to D7 are set to high impedance. When the I2C interface is selected, then D0 serves as the serial clock input pad (SCL) and D1 serves as the serial data input pad (SDAI). At this time, D2 to D7 are set to high impedance. |

| 28 | IREF | This is a segment current reference pad. A resistor should be connected between this pad and VSS. Set the current at 18.75uA. | |||||||||||||||
| 29 | VCOMH | This is a pad for the voltage output high level for common signals. A capacitor should be connected between this pad and VSS. |
