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. Feel free to check those out If you are interested in RP2350-based dev boards. W5100S-EVB-Pico2 and […]

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, […]
