It packs a 6-core Cortex-A78AE cluster, a 4-core Cortex-R52+ MCU domain (with lockstep and split-lock safety modes), a Nash BPU rated at 128 TOPS INT8, a Mali-G78AE GPU, and 24GB of LPDDR5 memory. It runs RDK OS (Ubuntu 22.04, Linux 6.1) and supports ROS 2 Humble via TogetherROS.Bot, with AI models run through the OpenExplorer toolchain and INT8 quantization. Two optional expansion boards add camera/GMSL inputs and CAN FD/real-time control interfaces. Compared to the Jetson Orin NX 16GB, the S100P trades CUDA/TensorRT/Isaac ecosystem support for a dedicated real-time MCU domain absent on Jetson. Pricing is $899 on DFRobot, with a cheaper previous-gen RDK S100 (12GB RAM, 80 TOPS) at $999.99 on Waveshare and $625.99 on Amazon. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How does the D-Robotics RDK S100P compare to the NVIDIA Jetson Orin NX 16GB for robotics? Both use Cortex-A78AE CPUs and LPDDR5 memory with MIPI camera support for ROS 2 robotics, but the RDK S100P has 6 A78AE cores at 2.0 GHz, a Nash BPU rated at 128 INT8 TOPS, and 24GB of LPDDR5 on a 96-bit bus, versus the Orin NX's 8 A78AE cores, 1024-core Ampere GPU, 32 Tensor Cores, 16GB LPDDR5, and up to 100 sparse INT8 TOPS at 25W. The S100P adds a 4-core Cortex-R52+ MCU with lockstep/split-lock real-time control, which Jetson lacks, while Jetson keeps its CUDA, TensorRT, and Isaac ecosystem. _Comparing edge AI boards for a robotics build gets easier when specs like these are tracked on daily.dev._ ### What is the price of the D-Robotics RDK S100P development kit? The RDK S100P development kit is sold for $899 on DFRobot. A previous-generation board, the RDK S100 without the P suffix, offers only 12GB of RAM and up to 80 TOPS instead of 128 TOPS, and is priced at $999.99 on Waveshare or $625.99 on Amazon, so buyers need to check which generation they are purchasing. _Track pricing and spec changes across edge AI hardware releases like this one on daily.dev._ ### Does the D-Robotics RDK S100P have a real-time control processor separate from its main CPU? Yes, the RDK S100P includes a 4-core Arm Cortex-R52+ MCU domain running at 1.2 GHz, separate from its 6-core Cortex-A78AE application cluster. One pair of R52+ cores runs in lockstep for safety while the other two support split-lock operation, allowing the MCU to handle time-critical tasks like motor and sensor I/O while the A78AE cores and BPU handle Linux and vision processing. _Engineers weighing dedicated real-time MCU domains for robot control follow hardware breakdowns like this on daily.dev._ ## Similar posts on daily.dev -
