Wiznet W5500 EVB Pico2 and W5100S EVB Pico2 Dev boards

Raspberry Pi RP2350 dev board features Ethernet RJ45 port with WIZNet W5500 or W5100S Ethernet controller

WIZnet has recently launched two new Raspberry Pi RP2350-based Ethernet boards – W5100S-EVB-Pico2 and W5500-EVB-Pico2 – based on different Ethernet controllers. The entry-level W5100S-EVB-Pico2 is built around the W5100S controller that features 4 independent sockets and 16 Kbytes of buffer memory. On the other hand, the W5500-EVB-Pico2 is built around the W5500, which features 8 sockets, 32 Kbytes of buffer memory, and improved security features such as OTP memory, Secure Boot, and Arm TrustZone technology. These make the W5500-EVB-Pico2 ideal for projects with robust network handling and advanced security measures. After the recent announcement of the $5 Raspberry Pi Pico 2 we have seen many development boards built around the RP2350 MCU, including the Challenger+ RP2350 WiFi6/BLE5, the Solder Party’s RP2350 Stamp, the Seeed Studio XIAO RP2350, the Cytron MOTION 2350 Pro, and more.

Raspberry Pi Pico Arduino core 4.0 adds support for RP2350 boards

Earle F. Philhower, III has just released the Raspberry Pi Pico Arduino core 4.0 with support for a range of Raspberry Pi RP2350 boards beside the official Raspberry Pi Pico 2. Shortly after the RP2040-based Raspberry Pi Pico board was released, we got two Arduino SDKs, the first being the community-supported Raspberry Pi Pico Arduino core maintained by Earle, and the second being the official Arduino Core Mbed 2.0 for boards as such as Arduino Nano Connect RP2040. We are again likely to have two Arduino SDKs for the RP2350 starting with the Raspberry Pi Pico Arduino core. Key changes in Raspberry Pi Pico Arduino core 4.0: Adds Raspberry Pi RP2350 support (Arm only; RISC-V cores are not supported at this stage) Migrates to Pico SDK 2.0 since it is required for RP2350 support and includes a new OpenOCD and Picotool. Tested features: SPI, I2C, LittleFS, EEPROM, PWMAudio, LWIP-based networking, […]


HDMI screw terminal adapter

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 […]

Pimoroni Explorer Starter Kit

Pimoroni Explorer board is a Raspberry Pi RP2350-based learning platform with 2.8-inch LCD, breadboard sensors and more

The Pimoroni Explorer board is an electronic prototyping board built around the Raspberry Pi RP2350 chip with a 2.8-inch LCD screen, a speaker connector, and various I/Os, which makes it easy to build circuits, prototype projects, and even make small robots. It also features a mini breadboard, tactile buttons, and crocodile clip terminals, making it suitable for both beginners and experienced makers. The RP2350 MCU was recently released by Raspberry Pi Limited along with the $5 Raspberry Pi Pico 2 board. Since that initial release, we have seen many RP2350-based development boards like the Cytron MOTION 2350 Pro, the Bus Pirate 5XL and 6, and many other development boards released, feel free to check those out if you are looking for development boards built around the RP2350 MCU.   Pimoroni Explorer board specifications Microcontroller  – Raspberry Pi RP2350B MCU CPU Dual-core Arm Cortex-M33 @150MHz with Arm Trustzone for secure boot Dual-core 32-bit […]

Raspberry Pi RP2530 HSTX interface

A closer look at Raspberry Pi RP2350’s HSTX high-speed serial transmit interface

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. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs. We’ll also check out some programming examples in C and MicroPython. The high-speed serial transmit (HSTX) interface is detailed in the RP2350 datasheet starting on page 1118 where it reads “The high-speed serial transmit (HSTX) interface streams data from the system clock domain to up to 8 GPIOs at a rate independent of the system clock”. Reading further, we also learn that it runs at 150 MHz enabling up to 300 Mbps per pin with DDR output operation, or a combined 2,400 Mbps over 8 pins if I […]

SparkFun RP2350 Pro Micro DEV

SparkFun Pro Micro – RP2350 development board comes with 16MB flash, 8MB PSRAM

The SparkFun Pro Micro – RP2350 is a compact and powerful development board built around the RP2350 chip from Raspberry Pi and equipped with 16MB flash and 8MB PSRAM. It follows the updated Pro Micro design and includes a USB-C connector, Qwiic connector, WS2812B RGB LED, Boot and Reset buttons, resettable PTC fuse, and both PTH and castellated solder pads.

Raspberry Pi Pico 2

$5 Raspberry Pi Pico 2 launched with Raspberry Pi RP2350 dual-core RISC-V or Arm Cortex-M33 microcontroller

The Raspberry Pi Pico 2 is an MCU development board based on the new Raspberry Pi RP2350 dual-core RISC-V or dual-core Cortex-M33 microcontroller with 520 KB on-chip SRAM, a 4MB flash, a micro USB port for power and programming and the same GPIO headers as the Raspberry Pi Pico board with an RP2040 dual-core Cortex-M0+ microcontroller with 264KB SRAM. The RP2350 embeds both an open-source Hazard3 RISC-V dual-core CPU and a dual-core Cortex-M33, but only one cluster can be used at a given time. Apart from the faster MCU cores and higher SRAM capacity, the RP2350 is about the same as the RP2040, albeit it also adds one extra PIO block bringing the total to three. One important new feature is built-in security when using Arm Cortex-M33 cores with Trustzone and other security features. Raspberry Pi RP2350 microcontroller Let’s have a closer look at the RP2350 microcontroller, before checking out […]
