I'm accustomed to using PIC microcontrollers at work, and Arduino (sometimes ESP) chips for hobby stuff.I've used the Raspberry Pi SBCs often, most frequently as a wifi-1-wire bridge to cheap arduinos a decade ago when it was the easiest option.This isn't like the Raspberry Pi SBCs or the MCUs I'm used to, but the learning curve wasn't too bad.I love that it makes experimenting with wireless signals approachable. The GPIO works much the same as other boards I've used. The board is fairly capable for a sub-$20 board, but it probably has to rely on software for some tasks normally offloaded to peripherals on other platforms.If you're not already deeply involved in another system this is a great starting point. It feels much more approachable than for instance Microchip stuff (they have prototyping boards, but the pricing starts at 3 digits). Well worth the price for a budding hobbyist.

This is a powerful little MCU with a plethora of functionality and connections such as SPI, ADC, I2C, etc... It is easy to use and setup up, you can design your own programs or flash existing UF2 files such as MicroPython. This kit does not come with the pins, attached or otherwise.

Ich habe das RP2350-Plus Development Board von Waveshare im Rahmen von Amazon Vine als kostenloses Testprodukt erhalten.Meine Bewertung gestalte ich dennoch so Objektiv wie möglich.Das RP2350-Plus Board von Waveshare ist eine spannende Alternative zum Raspberry Pi Pico. Die Kombination aus ARM Cortex-M33 und RISC-V Hazard 3 sorgt für ordentlich Rechenleistung und mit 520KB RAM sowie 4MB Flash ist auch genug Speicher für viele Projekte vorhanden.Der USB-C-Anschluss macht das Handling einfach, und durch den Anschluss für einen Lithium-Akku eignet sich das Board perfekt auch für mobile Anwendungen. Die vielen GPIOs, SPI, I2C und UART-Schnittstellen bieten viel Flexibilität für Bastler, Maker und Entwickler.Wer ein günstiges, aber leistungsfähiges Board für Embedded-Projekte sucht, macht hier nichts falsch. Läuft stabil und lässt sich gut programmierenPreis-Leistung: Das Produkt kostet aktuell 13,99€. Absolute Kaufempfehlung von mir.Lieferung: Die Lieferung erfolgte mit Amazon Prime - wie gewohnt, schnell und problemlos

Plenty of GPIO pins for a keyboard matrix. I bought this because it has USB-C, can't wait for the 2350 to be supported in QMK, have KMK running well on it.

Pros:- Decent build quality- Works with Thonny on Windows 11- On-board LED for easy testingCons:- No data cable included- No installation instructions providedThe Waveshare RP2350-Plus Low-Cost Development Board has a decent build quality, although no data cable is included. It was tested to work with Thonny under Windows 11. The on-board LED was programmed to turn on and off with a simple MicroPython script:from machine import Pinimport timeled = Pin("LED", Pin.OUT)while True:led.value(1) # Turn on the LEDtime.sleep(1) # Wait for 1 secondled.value(0) # Turn off the LEDtime.sleep(1) # Wait for 1 secondUnfortunately, the board does not come with any installation instructions.Here are the setup procedures that worked for me with Thonny:1) Install Thonny on Windows 112) Download the MicroPython for RP2350 preview .uf2 file dated 2024-11-29 on the MicroPython site3) Boot the board into bootloader mode by holding the boot button on the board before connecting the USB cable. A new drive will pop up4) Drag and drop the .uf2 file into the new drive5) If all the above steps are done right, the board will reboot automatically and the drive will disappear6) Now open Thonny and select the com port and you are ready to program it in MicropythonAll in all, the board appears to work well with Thonny on Windows 11 with the limited tests I have performed. I am happy with my acquisition.
