$6.5 RAK11160 LoRaWAN, WiFi, and BLE module pairs ESP32-C2 with STM32WLE5 for low-power, long-range IoT

RAK11160 ESP32-C2 STM32WL LoRaWAN module

RAKwireless RAK11160 is a new low-cost, low-power LoRaWAN, WiFi 4, and Bluetooth LE module based on ESP32-C2 (ESP8684) wireless microcontroller and STM32WLE5 LoRa SoC for LPWAN IoT applications. The company noticed that many people would combine their STMicro STM32WL-based RAK3172 WisDuo LoRaWAN module with an ESP32 module to add WiFi and/or Bluetooth connectivity to their projects besides LoRaWAN. So RAKwireless decided to offer a module combining both STM32WL and ESP32-C2 to offer a cheap and much more compact solution to their customers. RAK1160 was born. RAwireless RAK11160 specifications: LPWAN SoC/SiP – STMicro STM32WLE5 Core – Arm Cortex-M4 MCU @ 48 MHz Memory – 64 KB RAM Storage – 256 KB flash memory with ECC Wireless – Sub-GHz radio based on Semtech SX126x LoRaWAN 1.0.4 specification compliant Supported bands – EU433, CN470, IN865, EU868, AU915, US915, KR920, RU864, and AS923 LoRaWAN Activation by OTAA/ABP LoRa Point-to-Point (P2P) communication Tx Power Output – […]

ZimaBoard 2 Review – Part 2: An Intel N150 micro server and mini PC tested with ZimaOS, Ubuntu 24.04

We’ve already checked out the hardware of the ZimaBoard 2 micro server in the first part of the review with an unboxing and a teardown of the Intel N150 mini PC, followed by a first boot to ZimaOS and a walk-through of the web dashboard to see what features it had to offer. I’ve now connected two SATA drives to the ZimaBoard 2 and done further testing with ZimaOS, notably checking system information and testing storage and networking performance. I also installed Ubuntu 24.04 on the ZimaBoard 2 for further testing for people preferring to use the system as a mini PC with SATA storage. ZimaOS v1.4.1 update When I connected to the web dashboard again, there was a new update for ZimaOS v1.4.1. Before and after the update is completed, I was shown the change log with new features like a scheduled shutdown function and a list of bug […]

Seeed Studio XIAO-2CH-EM Review: 2-Channel Wi-Fi AC Energy Meter with two CT clamps, ESPHome preloaded

XIAO 2-channel Wi-Fi AC Energy Meter Review

We have received a review sample of an energy metering device from SeeedStudio called the XIAO 2-Channel Wi-Fi AC Energy Meter (XIAO-2CH-EM). This device uses a clamp-on CT (Current Transformer) method on the live wire that you want to measure, without needing to modify the existing electrical wiring. XIAO-2CH-EM comes with several key features such as dual CT sensors (CT1 and CT2), native ESPHome & Home Assistant Integration, precise measurement with factory calibration, and bi-directional power flow monitoring. While the XIAO-2CH-EM has 2 CT input ports, it will only ship with one CT clamp by default, but users can purchase an additional CT clamp if needed. The two CT channels operate independently, and each one can measure bidirectional power and supports devices using up to 100A of current. That should be enough for an ordinary home. The XIAO-2CH-EM comes pre-flashed with ESPHome firmware from the factory, meaning it can be […]

Intel Celeron N4020 dual-core mini PC sells for $45 with 4GB RAM, 128GB eMMC flash

We’ve seen x86 mini PCs for under $100 a few times, but I don’t think I’ve ever seen one going for under $50, and that’s exactly what the Wo-we HU-MNPC05-L mini PC has to offer as the system is sold for $44.99 on Amazon with an old Intel Celeron N4020 dual-core Gemini Lake Refresh processor first introduced in 2019. What’s even more surprising is that it’s not a barebone model like cheaper mini PCs usually are, but it ships with 4GB of RAM and a 128GB eMMC flash. No sane person would likely attempt to use the thing as a Windows Desktop, but it may be an option for Linux distributions for workloads similar to what you would typically run on a Raspberry Pi 4/5, or for older Windows applications, or as a basic HTPC. Wo-we HU-MNPC05-L specifications: SoC – Intel Celeron N4020 dual-core Gemini Lake Refresh processor @ 1.1 […]
