Comparison of Raspberry Pi 5 with 2GB and 8GB RAM – Hardware, benchmarks, and power consumption

The Raspberry Pi 5 with 2GB RAM was launched last week, and since I got a sample for review, I decided to compare it to the Raspberry Pi 5 with 8GB RAM to see if I could find any noticeable differences between the two boards. I’ll start with a visual inspection to show differences on the PCBA, then check system information, run some benchmarks, check power consumption, and finally try to open as many tabs in Firefox until the 2GB RAM is filled and the system becomes unusable. Raspberry Pi 5 2GB vs Raspberry Pi 8GB – visual inspection We should first have a quick look at the boards and packages there’s no obvious difference apart from seeing 2GB RAM and 8GB RAM on the respective packages. But if we look closer, we can see the resistors for memory capacity detection are in different locations for “2G” and “8G”, and […]

Raspberry Pi 5 PCIe HAT+ board features gigabit Ethernet, 4G LTE (mini PCIe), two USB 3.2 ports

Waveshare PCIe TO MiniPCIe GbE USB3.2 HAT+

Waveshare has recently introduced the PCIe to MiniPCIe GbE USB3.2 HAT+ for Raspberry Pi 5 adding gigabit Ethernet, a mini PCIe socket for 4G LTE, and two USB 3.2 Gen1 ports to the popular Arm single board computer. The HAT+ is compatible with IM7600G-H-PCIE/EG25-G-mPCIe series 4G LTE modules with 4G/3G/2G global band and GNSS positioning. Additionally, it has a gigabit Ethernet with an onboard RJ45 port, two USB 3.2 Gen1 ports, an onboard power monitoring chip, and EEPROM. All these features make this HAT useful for applications such as industrial routers, home gateways, set-top boxes, industrial laptops, industrial PDAs, and much more. We have previously written about many different types of HATs for the Raspberry Pi 5 designed by Waveshare including the Waveshare UPS HAT (E), the Waveshare PoE HAT (G), the Waveshare PCIe to USB 3.2 HAT+, and many other products. Feel free to check those out if you […]

HDMI to screw terminal adapters could be useful for Raspberry Pi RP2040 and RP2350 boards

The very idea of an HDMI to screw terminal adapters maybe seem moronic at first, but in an era of programmable IOs (PIO), and high-speed serial transmit (HSTX), those could end up being useful for boards or modules based on Raspberry Pi RP2040 or RP2350 since they’ve all be shown to support DVI output through HDMI connectors. There are a few boards that integrate an HDMI port such as the Olimex RP2040-PICO-PC, Solder Party RP2xxx Stamp Carrier XL, or Adafruit Feather RP2040 among others, but most boards don’t include an HDMI port. What they do typically have are GPIO headers, and an HDMI to screw terminal adapter would allow users to easily add an HDMI port to their existing board without soldering simply by using jumper wires, or with a bit more work an old HDMI cable. All HDMI to screw terminal adapters are pretty basic with an HDMI male […]

ANAVI Dev Mic is a digital omnidirectional microphone based on Raspberry Pi RP2040 MCU (Crowdfunding)

The ANAVI Dev Mic is an open-source microphone board from ANAVI Technology in Plovdiv, Bulgaria powered by the Seeed Studio XIAO RP2040 module and an omnidirectional digital microphone from STMicroelectronics. It is a compact and affordable product that outperforms USB microphones in artificial intelligence and machine learning voice applications. The design is simple and unassuming, with the Seeed Studio XIAO RP2040 module in the center, surrounded by a USB-C port for power and programming and 9 GPIO pins for extensibility. The STMicroelectronics MP23DB01HP microphone (MK1) is mounted on the top of the board with a small hole on the bottom. It is a compact, low-power, digital MEMS microphone capable of capturing sounds from different directions with very low distortion. It uses a PDM (Pulse-Density Modulation) interface created via the programmable inputs/outputs (PIO) on the RP2040. The ANAVI Dev Mic is applicable for conducting AI/ML research, building a voice recognition platform, […]

The Raspberry Pi 5 SBC is now available with 2GB RAM for just $50

The Raspberry Pi 5 has now a cheaper variant with 2GB of RAM going for just $50 following the launch of the Broadcom BCM2712 SBC in October 2023 with either 4GB or 8GB LPDDR4X-4267 SDRAM for respectively $60 and $80. At the time of the release, we also noted that cheaper variants with 1GB and 2GB RAM should become available later on simply because of the options on the silkscreen. When Eben Upton contacted CNX Software about the release of the Raspberry Pi 5 2GB RAM he explained that Raspberry Pi was “bringing the power of our most modern platform, and all of the optimisations we’ve developed since the launch of the larger memory SKUs last autumn, to a new lower price point”. Raspberry Pi 5 2GB RAM specifications: SoC – Broadcom BCM2712 (cost-optimised D0 stepping) CPU – Quad-core Arm Cortex-A76 processor @ 2.4 GHz with crypto extensions, 512KB per-core […]
