Debashis Das writes about the D-Robotics RDK S100P, a robotics single-board computer featuring a 6-core Cortex-A78AE CPU, a 4-core Cortex-R52+ real-time MCU domain, and a Nash BPU rated at 128 TOPS INT8, positioned against the NVIDIA Jetson Orin NX 16GB. The kit ships with 24 GB LPDDR5, runs an Ubuntu 22.04-based RDK OS with ROS 2 Humble, and includes expansion boards for additional MIPI/GMSL camera inputs and CAN FD ports.
- The R52+ cores support lockstep (safety) and split-lock modes, potentially eliminating a separate real-time controller
- Priced at $899 (DFRobot) or $999.99 (Waveshare); a $625.99 Amazon listing is the older RDK S100 with only 80 TOPS
- TOPS figures are not directly comparable to NVIDIA's since the two vendors measure inference performance differently
- The MCU expansion board adds 5× CAN FD at 8 Mbps, but its BMI088 IMU was unsupported in the V4.0.3 SDK
- Board supports up to 150 W max power draw in a 121 × 120 × 51 mm enclosure
