Cost-optimized quad-core Cortex-A35 board with a built-in audio codec, RGB/MCU display up to 720p, Wi-Fi and 4G, made for appliance, voice-control and smart-home HMIs.
Overview
The TV-RK3308 targets products where cost, audio and connectivity matter more than graphics performance. Rockchip’s RK3308 combines four Cortex-A35 cores at 1.3 GHz with an integrated audio codec (8 ADC / 2 DAC), which makes it a natural choice for voice-controlled devices, intercom-style terminals and appliance control panels. The board drives an RGB/MCU display up to 720p and is commonly paired with an 8-inch screen and multi-touch capacitive panel. Wi-Fi and 4G are onboard for connected products.
