ARIEC61850 understands IEC 61850. ARStack61850 measures and executes IEC 61850 in real time.

The portable C++20 stack remains rooted in the ARIEC61850 behavioral model, but the project north star is now broader: build an open, deterministic IEC 61850 instrumentation platform for hardware-timestamped Sampled Values/GOOSE/PTP injection, analysis, commissioning and real-time closed-loop testing.

Waveshare has put together a devkit built around the ESP32-C5-WROOM-1U module and a 3.5-inch capacitive touch IPS display. It is the largest ESP32-C5 board with a touch display seen so far, and it is meant for building voice and visual interfaces that talk to large online AI models. The 32-bit RISC-V processor runs at up to 240 MHz, with 384 KB of SRAM, 320 KB of ROM, 8 MB of PSRAM and 32 MB of Flash. The low-power RISC-V core, meanwhile, runs at 40 MHz.

The radio covers dual-band Wi-Fi at 2.4 GHz and 5 GHz, Bluetooth 5 LE and IEEE 802.15.4 for Zigbee 3.0 and Thread. So the board is not limited to classic connectivity: it can join a Matter or Thread home automation network without extra modules. Anyone who wants to start from a simpler base can still find an ESP32 development board with Wi-Fi and Bluetooth for their first experiments.
