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 […]

Integrated motor driver and controller bundles ESP32-S3 and TMC2209 for IoT applications

The PD Stepper is a NEMA 17 integrated stepper motor driver and controller board powered by USB power delivery that combines an ESP32-S3 wireless microcontroller, the Trinamic TMC2209 ultra-silent motor driver, and other components onto a single board for Smart Home and automation applications. The maker, Josh R., states that the PD Stepper isn’t another “just because we can” project. It addresses the need for an integrated motor driver and controller module that can used in compact or space-constrained designs. The ESP32-S3 SoC controls the other components on the board and provides wireless connectivity as well as access to development tools and libraries such as ESPHome and ESP-Now. The motor driver IC, Analog Devices’s Trinamic TMC2209, offers efficient, noiseless control of two-phase stepper motors. Other onboard components and connectors include an AS5600 magnetic rotary position sensor, a 3.3V buck converter, a Qwiic/Stemma QT connector, a motor connector, and an AUX […]

Microchip LAN887x industrial single-pair gigabit Ethernet transceivers can communicate over 40 meters of cable

Microchip LAN887x family of PHY Transceivers

Microchip has released the LAN887x family of single-pair gigabit Ethernet transceivers adding to their line of Single Pair Ethernet (SPE) devices. This new family of transceivers supports 100BASE-T1(compliant with IEEE 802bw-2015) and 1000BASE-T1(compliant with IEEE 802.3bp) network speeds and can handle extended cable lengths up to 40 meters. They also integrate time-sensitive networking (TSN) protocols and comply with ISO 26262 functional safety standards. Additionally, they can operate in low-power mode with features like EtherGREEN technology and OPEN Alliance TC10 sleep mode. All these features make this IC useful for applications such as automotive, industrial, avionics, robotics, and automation fields. Microchip previously released the LAN8770 100BASE-T1 Ethernet PHY Transceiver which has a max cable length of 15 meters for UTP (Unshielded Twisted Pair) cable and 40 meters for STP (Shielded Twisted Pair) cable. The speed was limited to 100 Mbps, but now, with the release of the new 1000BASE-T1 ethernet controllers, […]

Flexduino is an Arduino UNO clone made of a flexible PCB

YouTuber “EDISON SCIENCE CORNER” has designed yet another Arduino UNO clone but with a twist as the board is made out of a flexible PCB. Companies like JLCPCB, PCBWay, and others have been offering flexible PCB manufacturing services for a while, mostly for flat cables or small boards that need to fit around a case, but the Flexduino is a complete Arduino UNO clone made of a flex PCB, and it looks rather cool. The flexible Arduino board does work as shown with the RGB LED and power LED in the photo above and YouTube video below, but its usefulness is rather limited, and some corners had to be cut as for instance there’s no ground plane. Nevertheless, it’s a nice demo of flexible PCB technology. The video on the EDISON SCIENCE CORNER channel provides a short demo, shows how the PCB was designed (EasyEDA), and go through the ordering […]
