Raspberry Pi Pico 2 was released last month with a Raspberry Pi RP2350 microcontroller equipped with two Arm Cortex-M33 cores and two 32-bit RISC-V “Hazard3” cores with up to two cores usable at any time. So in this guide, we’ll show how to use the RISC-V cores on the RP2350 MCU, compare their performance against the Arm Cortex-M33 cores, and even … [Read more...]

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. … [Read more...]

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 framework along with the ESP-Zigbee-SDK for a while, but Arduino support was less straightforward. … [Read more...]

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. … [Read more...]

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. … [Read more...]

The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. … [Read more...]
