1.28 inch Round Touch Screen Display for XIAO 240x240 65k Colors RTC for All XIAO Compatible, HMI, Smart Home, Wearables

Round Display for XIAO is an extension board with capacitive touch screen and is compatible with all XIAO development boards. It features a fully covered touch screen on one side, designed as a radiant disc with a radius of 39 mm.

With a 1.28-inch circular touch screen that has a resolution of 240 x 240 pixels and 65K colors, this board presents the exhibition of clear and colorful images. It can be applied to design a programmable watch, wearable indicator, etc.

The high integration and rich peripherals on the other side of the XIAO extension board are impressive, with an onboard RTC, TF card slot, battery charging chip, and JST 1.25 battery interface, all within a compact 39 x 39mm size. That is, you can have a reliable timekeeping, a way to extend memory up to 32GB FAT, a charging method by the lithium battery.

The pins for Seeed Studio XIAO are all led out and no soldering is needed, which offers a convenient development experience. With its mini size, the XIAO extension board is ideal for wearable and small-volume projects. It is a versatile and powerful extension board that can be used for a wide range of projects, from displaying sensor data to creating interactive interfaces.
