Lilygo designs T-Display K230 development board with AMOLED touchscreen

Lilygo has introduced the T-Display K230 development board, designed with a compact form factor ideal for IoT and embedded systems applications. True to its name, the board features a 4.1-inch AMOLED touchscreen display with a resolution of 1232×568 pixels, offering a smartphone-like experience. Its dimensions are 104x51x15.5mm, and as of March 2025, it is available for purchase at $98.79.

The hardware is powered by the Kendryte K230 system-on-chip, which consists of two 64-bit RISC-V CPU cores—one running at 1.6 GHz with RISC-V vector extensions 1.0, while the other operates at 800 MHz without vector extensions. Additionally, it includes a Kendryte Processing Unit neural coprocessor, designed to enhance on-device machine learning and AI capabilities.

The T-Display module provides a range of wireless connectivity options, featuring a Realtek Wi-Fi module that supports 2.4 GHz Wi-Fi (802.11b/g/n) and a Semtech LoRa transceiver designed for long-range, low-power wireless communication. Additionally, it includes a 2-megapixel Galaxycore CMOS image sensor, capable of capturing 1080p video at 30 frames per second. Connectors are also available for up to two additional cameras.
