Home Assistant-compatible Makerfabs ESP32-S3-based energy meter features BL0942 energy metering IC

The Energy Meter for Home Assistant is an ESP32-S3-based single-phase energy monitoring and control module designed to work with Home Assistant via ESPHome. It measures real-time power and energy consumption and also has a remote on/off control. The device is built around the BL0942 calibration-free energy metering IC, which supports voltage, current, power, and energy measurements with less than 1% error. It operates directly from AC 100–240V, includes an onboard 15A relay for switching loads, and provides electrical isolation for safety. Connectivity is done through USB and Wi-Fi using ESPHome for easy firmware flashing, API encryption, and automatic discovery in Home Assistant. These features make it suitable for smart homes, DIY energy monitoring, smart sockets, home energy dashboards, and automation projects. Energy Meter for Home Assistant specifications: Core module – Espressif Systems ESP32-S3-WROOM-1 SoC – ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads […]

Quectel SRG091X and SRG093X NXP i.MX 9 industrial AIoT modules integrates Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

Quectel SRG091X and SRG093X NXP i.MX Smart AIoT module

After releasing the very powerful P895BD-AP AIoT module at CES 2026, Quectel now released two new low-power industrial AIoT modules based on NXP’s i.MX 9 series SoCs. The module integrates Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios through the IW610G chipset, so it can simply be dropped into a PCB to create a fully compliant Matter Border Router without any RF design or coexistence concerns. While both modules share the same 46 x 41.5 mm form factor and wireless capabilities, they are different in terms of CPU power as the SRG091X is an entry-level solution built around a single-core NXP i.MX 91 processor, while the SRG093X features dual-core NXP i.MX 93 SoC, which includes a Cortex-M33 real-time core and a neural processing unit (NPU) for edge AI workloads. The module supports LPDDR4/LPDDR4X memory, eMMC storage, and various I/O options, including dual Gigabit Ethernet, USB 2.0, CAN-FD, SPI, UART, I²C/I³C, ADC, […]

STM32MP21 Arm Cortex-A35/M33 MPU targets cost-effective applications in smart factories, homes, and cities

STMicroelectronics’ STM32MP21 microprocessor family combines a 1.5 GHz 64-bit Arm Cortex-A35 application core with a 300 MHz 32-bit Arm Cortex-M33 core for real-time processing. It is designed for “cost-aware” edge applications in smart factories, smart homes, and smart cities. The new STM32MP21 is a cost-optimized version of the earlier STM32MP23 and STM32MP25 that does without an AI accelerator (yes, those still exist!), GPU, H.264 decoder and encoder, or PCIe Gen2 / USB 3.0 interfaces. It still offers a MIPI CSI-2 camera interface, two Gigabit Ethernet interfaces with Time-Sensitive Networking (TSN), and strong security targeting SESIP Level 3 and PCI pre-certification. STM32MP21 specifications: CPU – Arm Cortex-A35 core running at up to 1.2 or 1.5 GHz with 128KB L2 cache Real-time MCU – Arm Cortex-M33 core with FPU/MPU running at up to 300 MHz GPU – None VPU – None AI accelerator – None Memory 456 KB SRAM 256KB AXI SYSRAM […]

M5Stack NanoH2 – An ultra-compact ESP32-H2 IoT development kit with Zigbee, Thread, and Matter connectivity

M5Stack NanoH2 is an ultra-compact, standalone IoT development kit powered by an Espressif Systems’ ESP32-H2 wireless SoC with support for Zigbee, Thread, and Matter, and designed for smart home and low-power wireless applications. It also features a built-in LED, an RGB LED, an infrared transmitter, a Grove port for expansion, a user button, and a USB-C port for power and programming. On the surface, it looks very similar to the Unit Gateway H2 introduced last March, with an ESP32-H2 SoC and a Grove connector. But while the earlier model is designed as an add-on board to other M5Stack products, the NanoH2 is a standalone development kit that you can use directly without another board from M5Stack.
