We’re clearing out the black SparkX version of this board so pick one up while they’re cheap! Other than color there is no difference between this board and its red cousin.
Pong on a coffee mug! Why not? This is a small flexible, grayscale OLED display. That’s right, we said flexible. We’ve been hearing about flexible displays for years, it’s finally here! You can’t fold it like paper but this OLED from Wisechip can be bent to a 40mm radius without damage. The display is than 0.5mm thick, less than 0.5 grams, and can display some impressive graphics with great contrast.
The OLED display is 1.81" long with 160x32 4-bit grayscale pixels. The interface is 3-wire SPI and each pixel requires 4 bits. This means you will need a processor capable of storing a local array of 80*32 = 2,560 bytes in order to truly flex (pun intended) the power of the grayscale display. Basic 8-bit Arduinos can communicate with the display and do things like text but graphics will be tricky.
The carrier board generates the 12V required to drive the OLED display. The carrier board also has a signal buffer so that you can drive the display from any 3.3V or 5V microcontroller. However, because of the nature of the TXB0104 you must power the board with 3.5V or more. Your microcontroller can be 3.3V or 5V but we recommend you power the carrier board with 5V.
We’ve ported the MicroOLED library so you can do things like print text (two sizes) and the neat 7-segment number font. The library is complete and can be downloaded from the Arduino library manager (search “flexible oled”). We’ve provided a pile of examples to get you started. You can even help us make the library better!
We do not plan to regularly produce SparkX products so get them while they’re hot!

這是一個小巧靈活的灰階OLED顯示器。沒錯,我們說靈活。我們已經聽說了多年的柔性顯示器,終於來了!你不能像紙一樣折疊它,但是Wisechip公司的這種OLED可以彎曲到半徑40mm而不會損壞。顯示器厚度大於0.5毫米,小於0.5克,可以顯示一些令人印象深刻的圖形,而且對比度很強。
OLED顯示屏為1.81英寸長,160x32 4位灰度像素,接口為3線SPI,每個像素需要4位,這意味著您將需要一個能夠存儲80 * 32 = 2560字節本地數組的處理器為了真正地展現灰度顯示的能力,基本的8位Arduinos可以與顯示器進行通信,並且可以像文本一樣進行操作,但是圖形會變得非常棘手。
載板產生驅動OLED顯示器所需的12V。載板還有一個信號緩衝器,以便您可以從任何3.3V或5V微控制器驅動顯示器。但是,由於TXB0104的性質,您必須使用3.5V或更高的電源為電路板供電 。您的微控制器可以是3.3V或5V,但我們建議您用5V電源給載板供電。
我們已經移植了MicroOLED庫,所以你可以做像打印文本(兩種尺寸)和整齊的7段數字字體。該庫是完整的,可以從Arduino庫管理器下載(搜索“flexible oled”)。我們提供了一堆例子來幫助您入門。你甚至可以幫助我們使圖書館更好!
