Add four Gigabit or 2.5Gbps Ethernet ports to the Raspberry Pi 5 with this expansion board

Waveshare PCIe TO 4 Ch Gigabit for Raspberry Pi 5

Waveshare PCIE TO 4-CH Gigabit/2.5G ETH Board (B) is a 4-port Gigabit or 2.5 Gbps Ethernet board designed for the Raspberry Pi 5. This board connects four RJ45 ports to the Pi’s 16-pin PCIe interface and also includes a mounting option for the Pi5 Connector Adapter (C). The only limiting factor is the Pi’s PCIe Gen2/Gen3 x1 interface, as the 2.5GbE ports share the available bandwidth and cannot operate at full speed simultaneously. The Gigabit Ethernet variant features Realtek RTL8153 USB to Ethernet controllers, while the 2.5GbE variant relies on RTL8156 controllers, and both integrate a VL805 PCIe to USB bridge chip. The board also includes status LEDs for link and activity indication, and draws power directly from the PCIe interface without requiring an external power supply. The device is plug-and-play and supports Raspberry Pi OS out of the box with no additional drivers required. Applications include routers, firewalls, network […]

LoRa, BLE, and GNSS tracker supports open-source software, solar charging, outdoor and indoor tracking

Ruictec's TD04 Asset Tracker

Designed by Ruictec in China, the TD04 is a LoRa-based low-power tracker that also features BLE and dual-band GNSS. It supports both indoor and outdoor positioning, and is suitable for fleet management, asset tracking, and geofencing over public or private LoRaWAN networks with minimal maintenance. The device combines GNSS (L1/L5) for outdoor positioning with BLE-based indoor tracking. It automatically switches between the two to optimize accuracy and power usage, delivering around 1–2 m accuracy outdoors and 2–4 m indoors. It is LoRaWAN 1.0.3-compliant, supports OTAA and ABP, and operates across multiple regional bands (EU868, US915, IN865, AS923, and others). Other features include a built-in motion sensor (G-sensor), configurable reporting and heartbeat intervals, iBeacon support, optional Bluetooth gateway mode, BLE-based configuration, OTA updates, and batch firmware upgrades. The device is powered by a 6000 mAh rechargeable battery and support 1.3 W solar panel input, enabling up to six months of standby […]

Forlinx FET1126Bx-S low-power Rockchip RV1126BJ industrial SoM powers SBC with 40-pin GPIO header

Forlinx FET1126BJ S Industrial SoM

Forlinx has recently released the FET1126Bx-S, a low-power SoM, which is based on the Rockchip RV1126B (commercial) or RV1126BJ (industrial) SoC. Designed for edge AI applications, the module is suitable for smart cameras, AIoT gateways, and intelligent monitoring systems where local video analytics, low power consumption, and long-term stability are required. It is easy to confuse the newer RV1126B/RV1126BJ with the original Rockchip RV1126, a 32-bit Cortex-A7-based SoC announced around 2020–2021. However, the newer RV1126B/BJ comes with a significant architectural upgrade with a 64-bit quad-core Arm Cortex-A53 processor (instead of the original 32-bit quad-core Cortex-A7) and a more powerful 3.0 TOPS NPU (up from 2.0 TOPS). This updated chip has only recently started appearing in products like Luckfox Aura SBC, Boardcon MINI1126B-P SoM (based on the RV1126B-P), GL.iNet Comet PoE, and GL.iNet Comet Pro KVMs, all of which were released just this year. This makes the FET1126Bx-S SoM one of the […]
