SpacemiT K3 16-core RISC-V SoC system information and (early) benchmarks

SpacemiT K3 is an upcoming RVA23-compliant 64-bit RISC-V processor based on X100 cores clocked at up to 2.5 GHz. So far, we had limited information, but SpacemiT gave remote access to one SpacemiT K3-powered server to Sander, and he was kind enough to share some system information and early benchmarks.

Let’s start with system information reported by inxi utility:

Geehy G32R430 Arm Cortex-M52 Encoder MCU features Arctangent accelerator, dual 16-bit ADC for industrial motion control systems

Last year, Geehy introduced the industry’s first dual-core Cortex-M52 real-time MCU, and has now followed up with the G32R430, an Arm Cortex-M52 Encoder MCU with two 16-bit ADCs and a hardware ATAN (arctangent) accelerator for sub-1 µs electrical angle computation in high-precision encoder and motion control systems. The MCU is clocked at 128 MHz and uses ITCM/DTCM tightly coupled memory for deterministic, zero-wait-state execution, alongside a 4KB cache for low-latency control loops. It integrates two 16-bit high-precision ADCs with support for synchronous sampling, along with an extra 12-bit ADC, multiple analog comparators, DACs, and an on-chip temperature sensor, allowing encoder designs to be built with very few external analog components. It also supports various encoder protocols, including BiSS-C, SSI, Tamagawa, and SPI, and includes generic interfaces like USART, SPI, and I²C. With a –40°C to +105°C industrial operating range, this MCU is suitable for servo motors, industrial robots, absolute and incremental […]

ESPHome 2026.1.0 optimizes memory usage on ESP32/ESP8266, adds Zigbee support on nRF52, WiFi roaming, and more

ESPHome 2026.1.0 open-source firmware has just been released with new features like automatic WiFi roaming and Zigbee support for Nordic Semi nRF52 targets, as well as memory optimization for ESP32/ESP8266 hardware, among many other changes. Other notable changes include security updates with the project replacing API password authentication with API encryption and requiring SHA256 authentication for OTA updates, better support for non-ASCII configuration, and updates to LibreTiny platforms (BK72xx, RTL87xx, LN882x), which received thread-safe WiFi, atomics, and deep sleep support. ESPHome developers used to advise users not to use ESP8266, not because it was not suitable for the task, but because the runtime heap on ESP8266 routinely dropped below 10k, and devices were unreliable. Since millions of ESP8266 devices were already deployed in homes, they decided to do something about it. The project was greatly helped thanks to increased support from the Open Home Foundation, which allows the project to […]
