產品敘述
WEO012832P是一款對角線為1.71吋COG圖形OLED顯示器模組，顯示畫面由128x32像素組成。此模組電源電壓典型值為 3V (VDD)，內建採用CH1115 IC，可支援I2C、SPI介面，驅動方式1/32 duty；50%棋盤格顯示電流為20mA @ VCC 12V (白色)。
WEO012832P 這款模組型號是WEO012832G模組的IC替代解決方案，機構尺寸及FPC出PIN定義兩款均相同。此款模組是COG結構OLED顯示屏，超薄、無需背光源，模組重量輕，功耗低，節能減碳。
適用於智能家電產品、攜帶型裝置、智慧醫療產品、量測儀器等產品；模組的工作溫度是-40℃至+80℃，儲存溫度-40℃至+85℃。

| 6 | __ CS |
This pad is the chip select input. When /CS = “L”, then the chip select becomes active, and data/command I/O is enabled. | ||||||||||||
| 7 | ___ 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. | ||||||||||||
| 8 | A0 | This is the Data/Command control pad that determines whether the data bits are data or a command. In I2C interface, this pad serves as SA0 to distinguish the different address of OLED driver. |
