Evaluation Boards

Upbeat Tech offers two evaluation boards built on its ultra-low-power RISC-V platform, helping customers accelerate development from always-on sensing to feature-rich AIoT products.

Each board is optimized for a different development focus:

Trina-Pi is designed for ultra-low-power and always-on operation. It is well suited for battery-powered devices that need to monitor sound or sensor data continuously for long periods.
Penta-Pi is a more advanced platform for wearables and AIoT development, with broader interface support for display, camera, audio, and external storage in more complex edge AI systems.

Penta-Pi (UP301 evaluation board)

Key Advantages

Low-power edge intelligence: Trina-Pi delivers excellent energy efficiency at 16.88 uW/MHz/DMIPS, making it a strong platform for always-on sensing and long battery life designs.
Rich multimedia and expansion: Penta-Pi supports MIPI DSI-2, camera connectivity, built-in DAC and phone jack output, plus SDIO 3.0 / eMMC 4.5.1 for data-intensive applications.
Built-in security foundation: Both boards support Secure Boot, PUF (Physically Unclonable Function), TRNG, and hardware-accelerated AES-256, SHA-256, and SM4.
Unified development workflow: Both platforms support Windows, Linux, and macOS with GCC, OpenOCD, JTAG debugging, VS Code, and a command-line toolchain, reducing effort when scaling across projects.
AI-ready software support: Developers can quickly start with CMSIS-NN, CMSIS-DSP, and LiteRT (TensorFlow Lite for Microcontrollers).
