Raspberry Pi Pico-sized RP2350 CAN development board features a clone of the MCP2515 CAN Bus controller

Waveshare has recently launched RP2350-CAN, a Raspberry Pi RP2350-powered CAN development board with onboard XL2515 CAN Bus controller and a SIT65HVD230 CAN transceiver. The board supports the CAN V2.0B protocol at up to 1 Mbps, and the XL2515 chip appears to be a clone of the popular Microchip MCP2515 CAN controller. The board includes the same 26 multi-function GPIO pins and USB-C port as found on the Raspberry Pi Pico 2. Other features include a DC-DC buck-boost converter (MP28164), BOOT and RESET buttons, a user LED, a selectable 120Ω CAN termination resistor, and CAN screw terminals. The CAN Bus board targets automotive, industrial control, and robotics applications.

Openviro Axe PoE is an RP2040-based environmental sensor for server rooms and cabinets (Crowdfunding)

Openviro Axe PoE is a rack-mountable, open-source environmental sensor designed to measure the temperature and humidity (and air pressure) in server rooms or cabinets with electrical equipment. The device is based on a Raspberry Pi RP2040 board with Ethernet connectivity housed in an aluminum enclosure and equipped with two RJ12 connectors for Bosch BME280 sensors with an accuracy of +/- 0.5°C. It provides better results than sensors placed in a machine that may be impacted by the internal components’ heat dissipation. For instance, the two sensor inputs can be used to measure the temperature and humidity of the intake and exhaust in a server rack. Openviro Axe PoE specifications: Microcontroller – Raspberry Pi RP2040 dual Arm Cortex-M0+ @133 MHz with 264 KB SRAM Storage – 16 MB flash memory Network – 10/100Mbps Ethernet RJ45 port via LAN8710Ai Expansion – 2x RJ12 connector for THP Probes Misc – 3x Buttons Power […]

W6300-EVB-Pico2 board combines RP2350 MCU with WIZnet W6300 QSPI Ethernet controller for 80+ Mbps data rate

W6300-EVB-PICO2 board with Raspberry Pi RP23500 and W6300 QSPI Ethernet controller

WIZnet W6300-EVB-Pico2 is a development board that combines a Raspberry Pi RP2350 MCU with the company’s new W6300 QSPI Ethernet controller capable of 80+ Mbps data rates. WIZNet has made several 10/100Mbps Ethernet controllers over the years that connect to microcontrollers via SPI, but the speed is often limited to 15 to 70 Mbps due to a low SPI clock frequency and small buffers. The WIZNet W6300 Ethernet controller can deliver higher speed thanks to a 150MHz system clock, a QSPI interface with four data lines, 64KB SRAM, and 4KB TX/RX buffer for each of the 8 sockets. W6300 QSPI Ethernet controller W6300 features and specifications: Host Interface – High-speed QSPI (MODE 0/3), system bus with 2 address signals & 8-bit data Internal 32KB SRAM for Tx/ Rx buffers (64KB in total) 8x independent sockets with 64KB Memory 10BaseT / 10BaseTe / 100BaseTX Ethernet PHY Integrated Auto negotiation (Full and […]

You can now buy Raspberry Pi RP2350 MCU for 80 cents and up, RP2354A and RP2354B variants coming soon

The Raspberry Pi RP2350 dual-core Cortex-M33/RISC-V MCU was first unveiled along with the Raspberry Pi Pico 2 in August 2024. Since then we have covered many Raspberry Pi RP2350 news and boards, but the microcontroller was hard to source for hobbyist and low-volume projects, which partially explains why companies like NextPCB had promotions offering free PCBA prototyping services for RP2350 designs. The good news is that Raspberry Pi has just announced general availability for the RP2350 microcontrollers starting at $0.80 per unit for the RP2350A in 3,400-piece reels, or $1.1 in single quantity, so anybody can buy the MCUs from their favorite distributor. The British company also announced the RP2354A and RP2354B variants with 2MB of stacked flash memory would soon be available to select partners and mass production will ramp up later this year. Here’s the current official pricing information for the RP2040 and RP2350 microcontrollers. Users can simply […]
