OpenC6 BIOS project brings PC-like firmware to ESP32-C6 MCU with network boot and OTA update support

OpenC6 BIOS for ESP32 C6

OpenC6 BIOS is an open-source project by Rompass that takes a different approach to MCU development. It adds a BIOS-like system to the ESP32-C6, so the system part and application code can run separately rather than being combined into a single firmware image. In traditional development, hardware setup, networking, and application code are combined into a single firmware image. But the OpenC6 BIOS operates differently: it runs as the base system on the ESP32-C6 and handles hardware initialization and system functions. Instead of flashing a full application each time, it can load small payload programs separately. These payloads can run from RAM or flash (XIP) and use system functions through a simple Application Binary Interface (ABI), without needing the full firmware. In some ways, it operates like AkiraOS, but with a BIOS-like interface. Key features of the OpenC6 BIOS architecture: Dynamic CPU scaling – Adjusts CPU frequency based on load […]

Synaptics Astra SRW1500 Cortex-M52 Edge AI MCU features Ethos-U55 NPU, Wi-Fi 6/7, Bluetooth 6.0, 802.15.4 connectivity

Synaptics SRW1500 Series AI MCU

Synaptics has introduced the Astra SRW1500 Series of AI-native Edge AI MCUs designed for smart IoT edge devices. The family features an Arm Cortex-M52 core, an optional Arm Ethos-U55 Neural Processing Unit (NPU), and tri-band Wi-Fi 7 or Wi-Fi 6, Bluetooth 6.0 LE, and 802.15.4 connectivity, in a single package. It targets low-latency on-device AI workloads such as voice-trigger detection, sound-event classification, and AI-enhanced Wi-Fi sensing. The series currently comes in four variants offering different wireless and USB options. Since sensing, AI processing, and wireless connectivity are integrated into a single chip, this approach helps reduce system costs, simplify PCB design, and lower power consumption in devices such as smart home hubs, building automation systems, and home appliances. Synaptics SRW1500 Series specifications: CPU Arm Cortex-M52 application core up to 200 MHz with Arm Helium (MVE) vector extensions for DSP and ML Arm Cortex-R4 WiFi core with 960 KB SRAM and 1408 […]

$13 Qualcomm QCC74xM EVK offers Wi-Fi 6, Bluetooth 5.4, and 802.15.4 connectivity (Bouffalo Lab BL618 inside)

The Qualcomm QCC74xM EVK

Back in November 2024, we wrote about Qualcomm’s QCC730M and QCC74xM modules for low-power IoT devices, but at the time, there was no evaluation board EVK for those SoCs. Fast forward to today, and the official development boards for the QCC74x series have finally been released, complete with a surprisingly affordable price tag. The Qualcomm QCC74xM EVK is a tri-radio evaluation board with Wi-Fi 6, Bluetooth 5.4, and IEEE 802.15.4 (Thread/Zigbee) with a price tag of just over $13. But what is interesting is that, while it carries the Qualcomm brand, documentation from the Zephyr Project clearly shows that the QCC74x series is actually based on and mostly equivalent to the Bouffalo Lab BL61x series, specifically the BL618. Qualcomm QCC74xM EVK specifications: Wireless Module – Qualcomm QCC74xM LGA Module (QCC743M, QCC744M, or QCC748M depending on the board variant) CPU – 32-bit RISC-V processor (RV32IMAFCP) @ up to 325 MHz with FPU […]

wolfIP – An open-source, lightweight TCP/IP stack with no dynamic memory allocations for embedded systems

wolfip TCP/IP library no memory allocations

Better known for its open-source wolfSSL SSL/TLS library, wolfSSL (the company) has now released the wolfIP open-source, lightweight TCP/IP stack with no dynamic memory allocations (e.g., no malloc calls) designed for resource-constrained embedded systems.

The company highlights that wolfIP “supports both endpoint-only mode and full multi-interface support with optional IP forwarding. By default, it operates as a network endpoint, but can be configured to forward traffic between multiple network interfaces”.

Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface

M3333 Series MCU

Nuvoton’s new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A,  Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols, completely offloading the CPU to run fluid, dynamic LED effects. It comes in two variants, the M3333 series and the M3334 series, with the latter adding a high-speed USB 2.0 OTG controller with an integrated PHY. NuMicro M3331 specifications: MCU core – Arm Cortex-M33 32-bit CPU @ 180 MHz with single-precision […]
