UK-based embedded device manufacturer, SB Components, has launched a crowdfunding campaign for a 1.28-inch touch LCD HAT with a goal of £3,000. The Kickstarter product page gives us more details on the 1.28-inch display, which has been over-subscribed to reach £3,522 (as of writing). This shows the community’s support to send the hardware into mass production, and the pledging options start at £38 to get the round-touch LCD HAT for your Raspberry Pi computer. The early bird £35 has been sold out, and interested people had to pledge to buy the expensive options.

At the heart of the SB Components 1.28-inch round LCD HAT is a capacitive touch control ICU with a high-performance self-capacitance touch clip. The LCD HAT has three main components as part of the hardware– a full-touch LCD display, a touch panel, and a joystick to move around for various actions. The full HD display has a resolution of 240×240 pixels and the 1.28-inch colour IPS TFT display panel has a GC9101A controller and panorama view angle. The touch panel is a capacitive screen with support for up to 13 sensing channels, and >100Hz refresh rate. The single-point gesture and two-point options are key highlights of the onboard touch panel.
