Waveshare RP2350-GEEK USB development board doubles as a debugger for Raspberry Pi and other Arm boards

Waveshare has recently launched the RP2350-GEEK USB development board which can also be used as a debugger for Raspberry Pi boards and other Arm-based targets. Built around the Raspberry Pi RP2350 MCU this development board/debugger features a 1.14-inch 65K color IPS LCD, a USB Type-A interface, a microSD card slot supporting SDIO and SPI communication, 16MB NOR-Flash, and multiple interfaces, including 3-pin SWD, USB to UART, and I2C ports. The board is compatible with standard CMSIS-DAP debugging tools like OpenOCD, which attaches to Raspberry Pi’s 3-pin debug connector for debugging. It also features open-source firmware for easy upgrades. Housed in a plastic case, the development board looks like a USB drive and is suitable for debugging, testing, and firmware development in IoT, embedded systems, and educational projects. Waveshare RP2350-GEEK Raspberry Pi debugger specifications Microcontroller – Raspberry Pi RP2350A MCU CPU – Dual-core Arm Cortex-M33 processor @ 150MHz Memory – 520KB internal RAM […]

$7 Raspberry Pi Pico 2 W board launched with 2.4 GHz WiFi 4 and Bluetooth 5.2 wireless module

As expected, the Raspberry Pi Pico 2 W – the wireless version of the Raspberry Pi Pico 2 – is now available with an extra 2.4GHz WiFi 4 and Bluetooth 5.2 wireless module at an official price of $7. We’ll go through the specs and perform a mini review in this post trying out both WiFi and Bluetooth code samples. It’s not the first Raspberry Pi RP2350 with WiFi and Bluetooth we’ve seen, as Pimoroni introduced the Pico Plus 2 W board with an RP2350B MCU and Raspberry Pi RM2 Wi-Fi and Bluetooth module, and iLabs launched the Challenger+ RP2350 WiFi6/BLE5 board relying on ESP32-C6 wireless module. However, the Raspberry Pi Pico 2 W is the official board, is cheaper, and will certainly be the most popular/widely used. Raspberry Pi Pico 2 W specifications Raspberry Pi Pico 2 W specifications: SoC – Raspberry Pi RP2350 CPU Dual-core Arm Cortex-M33 @ […]

Black Friday and Cyber Monday 2024 – International deals and coupons

While Black Friday and Cyber Monday used to be a US-only event, it changed many years ago, and we’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, since a large portion of our audience cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events that will take place from November 21 until December 2 this year. So I’ve gathered some international Black Friday and Cyber Monday 2024 deals and discount coupon codes from relevant manufacturers and popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress’ Black Friday and Cyber Monday 2024 event has already started. There are three periods: Nov 19-21 PST – Warm Up event where users can find and add items to the cart before purchasing during the main event. Nov 22-30 PST – “On Sale” event with discounts up to […]

High-speed data acquisition with Raspberry Pi Pico 2’s HSTX interface and HDMI to USB 3.0 video capture dongle

Raspberry Pi Pico 2 high-speed data acquisition

We previously explained the HSTX high-speed serial transmit interface of the Raspberry Pi RP2350 microcontroller was mostly useful for video outputs and display interfaces since it can only transmit, and not receive data. But Steve Markgraf found another use case for the HSTX interface – high-speed data acquisition – combining a Raspberry Pi Pico 2 board with the DVI Sock board for Pico and one of those cheap MS2130-based HDMI to USB 3.0 video capture dongles. He managed to stream out up to 75 MB/s of real-time data from an overclocked RP2350 to a host computer with a USB 3.0 port. The Adafruit Feather RP2350 HSTX board should also work, but also not been tested. Steve’s “hsdaoh-rp2350” data acquisition over HDMI firmware is based on the dvi_out_hstx_encoder example from Raspberry Pi using the HSTX interface for DVI output and code by Shuichi Takano implementing the HDMI data island encoding required […]

Giveaway Week 2024 winners announced!

We’re now ready to announce the winners of CNX Software’s Giveaway Week 2024. We offered some of the review samples we tested (and some we did not test) in the last year, and for the fourth year running, RAKwireless also gave away two IoT development kits shipped directly to winners. This year’s prizes also included a RISC-V motherboard, a 3D depth camera, a few Arm development boards, two touchscreen displays, and an Alder Lake-N mini PC/router. All those products can be seen in the photo, minus some accessories. You’ll find more than seven devices because we organized the third Giveaway Week on CNX Software Thailand simultaneously with four prizes. We had seven winners on CNX Software: Jupiter RISC-V mini-ITX motherboard – François-Denis, Canada Orbbec Femto mega 3D depth and 4K RGB camera – Reifu, Japan RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit – OldCrow, Portugal Mixtile Core 3588E development kit […]
