BitNetMCU project enables Machine Learning on CH32V003 RISC-V MCU

Neural networks on the CH32V003

Neural networks and other machine learning processes are often associated with powerful processors and GPUs. However, as we’ve seen on the page, AI is also moving to the very edge, and the BitNetMCU open-source project further showcases that it is possible to train and run inference low-bit quantized neural networks using low-end RISC-V microcontrollers such as the inexpensive CH32V003. As a reminder, the CH32V003 is based on the QingKe 32-bit RISC-V2A processor, which supports two levels of interrupt nesting. It is a compact, low-power, general-purpose 48MHz microcontroller that has 2KB SRAM with 16KB flash. The chip comes in a TSSOP20, QFN20, SOP16, or SOP8 package. To run machine learning on the CH32V003 microcontroller, the BitNetMCU project does Quantization Aware Training (QAT) and fine-tunes the inference code and model structure, which makes it possible to surpass 99% test accuracy on a 16×16 MNIST dataset without using any multiplication instructions. This performance […]

Arduino Pro Opta D1608E/D1608S expansions feature electromechanical or solid-state relays, 16 I/Os

Arduino Pro Opta Ext D1608S and D1608E

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that the D1608E features 8 electromechanical relays (EMRs) whereas the D1608S features solid-state relays (SSRs). Other than that both expansion modules have 16x programmable I/Os (0-24 V digital / 0-24 V analog) which doubles the number of I/Os we have seen on the Opta micro PLC. Both are compatible with the Arduino IDE and the PLC IDE and are easy to install on a DIN rail. These features make it suitable for control, monitoring, and predictive maintenance applications. Previously we have seen Arduino launch a PLC Starter Kit for those who want to get started with PLCs. Additionally, we have written about ESP32-powered PLCs, Raspberry Pi-powered PLCs, and more. Feel free to check those out if you […]

NanoCell V2.1 battery-powered ESP32-C3 IoT board runs ESPHome for Home Assistant integration

nanocell v2 stack

The NanoCell V2.1 is a development board built around the Espressif ESP32-C3 SoC (system-on-a-chip) preloaded with ESPHome firmware for low-power applications and improved Lithium battery management. The development board is a white printed circuit board with gold-plated contacts and a battery fuel-gauge IC, designed by Frapais’ lab in Greece. As the name suggests, the NanoCell V2.1 is the latest in a series of iterations of ESP32-C3-based devices targeted at low-power applications. Compared to earlier versions, it offers a better user experience and improved power efficiency. It features a buck-boost converter that reduces standby current consumption to 66uA (excluding the current consumed by the ESP32 module). The battery management system (BMS) integrated circuit supports accurate capacity measurement and protects connected Lithium batteries from overcharging and other harmful scenarios. Also, two LEDs on the board serve as power and charging indicators to relay the board’s status. It is based on the same […]

AMD Ryzen 5 5500U mini PC goes for $177 with 8GB RAM, 128GB SSD

Inexpensive AMD Ryzen 5 5500U mini PC

Among all the inexpensive Intel Alder Lake-N mini PCs, ZXIPC is selling a no-name AMD Ryzen 5 5500 mini PC for $177 with 8GB of RAM and a 128GB SSD, or $143.03 as a barebone system. This weekend, I compared the benchmarks of various Intel Alder Lake-N processors using results from our mini PC reviews, and one user asked me whether I could do the same for AMD systems: It would be interesting to compare the performance on these to similarly priced AMD offerings. I’m specifically thinking here of Mini PCs based on the Ryzen 5560U and the Ryzen 5800U/H Since we haven’t reviewed this type of mini PC, I won’t be able to do such a comparison, but I was still intrigued, as most AMD mini PCs I had seen sold for at least $300. So I went to Aliexpress and found a few AMD Ryzen 5/7 mini PCs […]
