Waveshare RP2350-GEEK USB development board doubles as a debugger for Raspberry Pi and other Arm boards

Waveshare has recently launched the RP2350-GEEK USB development board which can also be used as a debugger for Raspberry Pi boards and other Arm-based targets. Built around the Raspberry Pi RP2350 MCU this development board/debugger features a 1.14-inch 65K color IPS LCD, a USB Type-A interface, a microSD card slot supporting SDIO and SPI communication, 16MB NOR-Flash, and multiple interfaces, including 3-pin SWD, USB to UART, and I2C ports. The board is compatible with standard CMSIS-DAP debugging tools like OpenOCD, which attaches to Raspberry Pi’s 3-pin debug connector for debugging. It also features open-source firmware for easy upgrades. Housed in a plastic case, the development board looks like a USB drive and is suitable for debugging, testing, and firmware development in IoT, embedded systems, and educational projects.

A first look at the Raspberry Pi Development Kit for CM5

Raspberry Pi Development Kit for CM5 Raspberry Pi OS

Raspberry Pi has just launched the Compute Module 5 (CM5) and the company sent me a “Raspberry Pi Development Kit for CM5” for review and to play around with the new Broadcom BCM2712 system-on-module succeeding the Raspberry Pi Compute Module 4 (CM4) introduced in 2020. Today, I’ll have a first look at the development kit checking out the hardware, connecting accessories, booting it up to Raspberry Pi OS, and collecting some basic system information. I’ll do a more in-depth review in a few weeks. Unboxing of the Raspberry Pi Development Kit for CM5 I received the kit in a package reading “Raspberry Pi Development Kit” and “For Raspberry Pi CM5”. That’s a good start… The bottom side lists the package’s content which I will check out shortly, and a link to the documentation. Let’s see what we have with the Raspberry Pi Development Kit: a Raspberry Pi IO Case, a […]

Raspberry Pi CM5 launched with Broadcom BCM2712 SoC, up to 16GB LPDDR4 ECC memory

The Raspberry Pi Compute Module 5, or Raspberry Pi CM5 for shorts, is now available with up to 16GB LPPDR4 ECC memory, up to 64GB eMMC flash, and an optional WiFi 5 and Bluetooth 5.0 LE wireless module. It has the same form factor as the Raspberry Pi CM4 and CM4 Lite launched in 2020 but delivers a significant performance boost. The Raspberry Pi CM5 is basically a tiny version of the Raspberry Pi 5 SBC designed for embedded applications with a Broadcom BCM2712 quad-core Cortex-A76 SoC, and offered with 2GB to 16GB RAM, optional 16GB to 64GB eMMC flash, and optional WiFi 5 and Bluetooth 5.0 module. As usual, there are also Raspberry Pi CM5 Lite versions without any eMMC flash meant to be booted from a microSD card or an SSD on the carrier board. Raspberry Pi Compute Module 5 Raspberry Pi CM5 specifications: SoC – Broadcom BCM2712 […]

GEEKOM Mini Air12 Lite Review – Part 3: Ubuntu 24.04 on a low-cost mini PC

GEEKOM Mini Air12 Lite Ubuntu 24.04 review

We have already checked the hardware of the GEEKOM Mini Air12 Lite mini PC in the first part of the review, before testing the low-cost Intel Processor N100 mini PC with its 8GB RAM and 256GB SATA SSD running Windows 11 Pro in detail in the second part. We’ve now had time to test the GEEKOM Mini Air12 Lite with Ubuntu 24.04 in the third and final part of the review. We’ll test the features in Linux, run some benchmarks, evaluate storage and network performance, play some 4K and 8K videos in YouTube playback, perform a stress test to check its thermal design, and finally measure the mini PC’s fan noise and power consumption. We’ll also compare the results in Linux to the earlier GEEKOM Mini Air12 mini PC with the same CPU, but better specs and a higher price. A challenging Windows 11 / Ubuntu 24.04.1 dual boot installation […]

Renesas RRH47000-EVK board integrates RRH47000 CO2 sensor with ±75 ppm accuracy, relative humidity and temperature sensors

Renesas has recently released the RRH47000-EVK evaluation board based on the RRH47000 CO2 sensor using non-dispersive infrared (NDIR) technology to measure CO2 levels accurately (±75 ppm typical) within the 0-5000 ppm range. The sensor also includes built-in sensors for relative humidity and temperature, operates at low power, and supports either UART or I2C interface to the host. These features make this device useful for applications like HVAC systems, industrial automation, building control, air quality monitors, home appliances, IoT devices, and agriculture. Previously we have written about the Sensirion SCD40 CO2 sensor which also uses NDIR to measure CO2 levels very accurately, while the Infineon PASCO2V15 CO2 sensor relies on photoacoustic spectroscopy (PAS) to detect CO2 levels. The Sensirion sensor can also measure humidity and temperature, but the Infineon sensor is designed to measure CO2 only. Renesas RRH47000 specifications: CO2 sensor Measurement range – 0 ppm to 5000 ppm Accuracy – […]
