Luckfox Lyra boards feature Rockchip RK3506G2 triple-core SoC, display interface, optional Ethernet port

Luckfox Lyra RK3506G2 RJ45 display interface

The Luckfox Lyra boards feature a Rockchip RK3506G2 triple-core Arm Cortex-A7 SoC with one Cortex-M0 real-time core, 128MB on-chip DDR3, a MIPI DSI display interface, and built on a 22nm process. Three versions are available with the Luckfox Lyra, Lyra B (with 256MB flash), and Luckfox Lyra Plus offering similar features, but the longer Plus model also adds a 10/100Mbps Ethernet RJ45 connector besides having 256MB SPI NAND flash. These are Luckfox’s first boards featuring the RK3506G2 processor, offering Ethernet connectivity and a display interface. But it’s not quite the first Arm Linux board from the company with Ethernet and a display interface, and we covered the Luckfox Pico Ultra micro development board all based on a Rockchip RV1106G3 SoC earlier this year. The company also introduced the similar-looking LuckFox Pico Pro and Pico Max boards powered by an RV1006G2 SoC in February, but instead of a display interface, they […]

Sensy32 Board is an ESP32-S3 sensor platform with up to six sensors for environmental monitoring in IoT applications

The Sensy32 Board is a compact sensor platform powered by Espressif’s flagship ESP32-S3 WiFi and Bluetooth microcontroller. The development board brings different monitoring devices together on the same PCB for easier integration into IoT ecosystems. It is a multipurpose device with several sensors bundled to measure and monitor ultraviolet light intensity, altitude, pressure, orientation, humidity, temperature, motion, and human presence. It includes a 9-degree-of-freedom inertial measurement unit (IMU) for 3D space orientation, while the built-in MEMS microphone can be used for audio input in voice detection and noise measurement applications. The onboard ESP32-S3 microcontroller powers the array of features and also offers Wi-Fi and Bluetooth Low Energy connectivity. The Sensy32 ESP32-S3 sensor platform also integrates an LCD screen for immediate feedback and real-time monitoring. We have covered other ESP32-based environment sensors such as the Qsen-07 multi-sensor board, AirGradient ONE, MoreSense MS-06, and Studio LUFF’s Air Quality Sensor. Sensy32 specifications: MCU […]

Raspberry Pi CM5 review with different cooling solutions (and camera tribulations)

Raspberry Pi CM5 IO board cooling heatsink active cooler

The day of Raspberry Pi CM5 release, I published a mini review of the Raspberry Pi Development Kit for CM5 showing how to assemble the kit and boot Raspberry Pi OS, and I also ran sbc-bench benchmark to evaluate the performance. Sadly, the Broadcom BCM2712 CPU did throttle during the test meaning cooling was not optimal when the CM5 IO board was inside the IO Case and the Compute Module 5 was only cooled by the fan. So today, I’ll repeat the same test with other cooling solutions namely the official Raspberry Pi Cooler for CM5 (that’s a heatsink only), and EDATEC’s CM5 active cooler similar to the active cooler for the Raspberry Pi 5, but designed for the CPU module. But before that, I’ll do some house cleaning so to speak since last time, I booted Raspberry Pi OS from an NVMe SSD and I noticed the camera did […]
