Caution: handle with care. This is a bare LCD so corners have very thin glass that can crack under pressure. Handle LED units very lightly during installation. Once installed and encased, the main LED panel is not as sensitive as the internal corners.

RAK1921 is a WisBlock OLED display based I2C SSD1306.
 A ready-to-use SW library and tutorial makes it easy to visualize data of your WisBlock solution.

RAK1921 can be used for both text and graphic display in your application.

RAK1921 combined with the RAK4631 WisBlock Core gives your solution an user interface that is even in bright environments easy to read.

RAK1921 is ideal for battery-powered applications because of its low power consumption. In addition, the WisBlock system allows to power down the module completely to reduce the power consumption of the system even more.

Bulk/High Value Order Returns

Due to the labor required to package and ship bulk orders, as well as cost and stock issues involved in replenishing items, bulk orders of 5 pieces or more are not returnable unless the equipment is defective or mis-advertised, or a return period is prenegotiated. For non-defective returns over $500, a restocking fee may be deducted from the refund to cover bank or card processing fees.


Items on backorder or preorder will ship as estimated on the item page. You can cancel an order any time up until shipment. Orders with expedited shipping will arrive in the advertised time after the order ships, not after the order is placed.


If you want to cancel an order, please email or call us at (352) 372-9902. If your item has not been shipped, we will cancel the order and provide a full refund.
