⚡ LILYGO T-Display K230 RISC-V AI dev kit

LILYGO has released the T-Display K230, a handheld development kit centered on Canaan’s Kendryte K230 dual-core 64-bit RISC-V processor. The device targets embedded applications requiring local AI inference and wireless connectivity, featuring a 4.1-inch AMOLED touchscreen as its primary interface. Optional accessories include a detachable keyboard with battery and nRF9151 cellular connectivity for LTE-M/NB-IoT and GNSS support.

The core specifications include 1GB of LPDDR4 RAM, a 2MP camera, HDMI output, Ethernet, and WiFi 4. Wireless communication options extend to LoRa, with the kit offering either an SX1262 or LR2021 transceiver. This combination makes the hardware suitable for remote monitoring and wireless communication projects where power efficiency and AI capabilities are required.

The Kendryte K230 SoC integrates a 64-bit RISC-V CPU running at 1.6GHz with RISC-V Vector Extension 1.0 and a 64-bit FPU. A secondary 800MHz RISC-V processor supports the RV64GCB instruction set. An AI accelerator (KPU) handles INT8 and INT16 operations, compatible with TVM, TensorFlow, PyTorch, and ONNX frameworks. Performance benchmarks indicate Resnet 50 at over 85fps and Mobilenet_v2 at over 670fps at INT8 precision.
