The Titan Mini is a smaller and considerably cheaper model of the RA8P1 Titan board launched in 2025 for AIoT purposes and RT-Thread RTOS improvement.
It nonetheless incorporates a Renesas R7KA8P1 Cortex-M85/M33 microcontroller with an Arm Ethos-U55 NPU, however comes with lower-capacity reminiscence and storage chips (32MB SDRAM and 8MB QSPI flash), drops the RJ45 Ethernet ports with a single FPC Ethernet connector, amongst different cost-saving measures. The one profit I see apart from the smaller dimension and barely lower cost is the presence of a microphone and a speaker connector for audio purposes.
Titan Mini specs:

You’ll want to make use of an non-compulsory FPC to RJ45 cable if you wish to use Ethernet, and a 5MP OV5640 digicam module can also be provided as an choice. You possibly can carry out debugging by way of an non-compulsory “HSLink Debug Package” linked to the JTAG header.
RT-Thread offers an SDK/BSP for the board on GitHub with libraries and numerous code samples, together with a blinking LED, a show and digicam demo, an Ethernet pattern, an NPU-accelerated AI face detection demo, and a WAV audio participant. The docs listing contains some documentation, together with some misnamed “Titan_Mini_datasheet.pdf” and “Titan_Mini_user_manual.pdf” information which are generic RA8P1 datasheet and consumer’s handbook as a substitute. No less than the PDF schematics look actual…
RT-Thread sells the Titan Mini board for $44.23 on AliExpress, however that doesn’t embrace the Ethernet cable, including $7.66, during which case the overall value could be $51.89, or greater than the $50 requested when the Titan board was launched in 2025, though it’s now $62.41. The costs are earlier than delivery and eventual taxes. As a aspect notice, the corporate advised us they don’t ship to the European Union resulting from “regulatory necessities”. That’s most likely as a result of the board lacks some certifications, and I requested what these have been, however the firm couldn’t reply in time for this text.
