General thoughts on the board:Pros* Acrylic backplate is a nice touch and lets you (carefully) stand the whole board up on its side.* All included functions work fine (RGB led, regular leds, buttons, joystick, beeper, screen, etc)* Convenient access to all pico board pins.Cons* Only two user addressable regular LEDs. Having at least 4 user addressable would have been nice.* Acrylic backplate kind of a pain in the rear to install.* Confusing demo firmware distribution. You'll get a zip file with like 5 firmware files in it but only one will work properly. Sloppy.* Big con for me: The 320x480 resolution of the screen is just too large for the amount of RAM the pico has for fast display. Even with a RGB332 format that you convert to the screen's native RGB565 on transfer you're looking at 153600 bytes for a framebuffer plus another 512 bytes for the RGB332 to RGB565 lut. It's not a deal breaker because the screen certainly does work as shipped but if you were hoping for 30+ fps updates you will not find that here. The LVGL based demo shows you can do some simple gui interfaces but you'll notice the speed is quite low especially with FreeRTOS in there.For my purposes, I was able to get faster update speeds by using an internal 160x240 RGB332 framebuffer and using DMA and a PIO to pixel double the buffer horizontally and just doubling up the line draws vertically. That brings the internal framebuffer down to 38400 bytes which fits comfortably enough in the pico's ram. However, it also is halving the screen resolution so YMMV.tl;dr: Screen works nicely but limited ram makes it quite slow on the updates. However, you can hack around it depending on what you want to do with the display.OverallHappy with the purchase. Arrived quickly and it was well packaged. I appreciate the convenience of the thing for prototyping. The screen is too large for my performance desires, however.

très intéressant/élégant kit pour developper et/ou pratiquer..le programme de démo est sur le site et comme le pico devient un volume de mémoire à la connexion, il suffit de glisser le programme comme on fait avec une photo d’un dossier à l’autre, puis déconnecter et reconnecter le câble usb pour le lancer.. par contre ce démo n’est pas éditable (et la version python ne m’intéresse pas) préférant écrire en c++..alors, je l’ai programmé avec Arduino IDE en utilisant ces 4 bibliothèques:SPI.hAdafruit_NeoPixel.hAdafruit_GFX.hAdafruit _ST7796S_kbv.het ces bibliothèques contiennent suffisamment d’exemples pour comprendre comment utiliser le potentiel de cette carte.. les adresses pour les items (buzzer, leds, boutons poussoir, lcd, enfin tout) sont tel qu’indiqué sur le site du concepteur..le joystick n’est pas précis quand il est relâché, il suffit de faire -500 (pour avoir le centre à zero) avec une compensation en X et Y, puis diviser par 10 pour le rendre moins instable et plus utile.. pour ma part, j’aurais préféré ne pas l’avoir ou avoir un potentiomètre ordinaire.. noter que le ADC du pico est de nature bruyant (12 bits vient avec "sensibilité") et donc, pour avoir une meilleure référence à zéro, il suffit d’activer un autre ADC dont l’entrée est mise à la masse, lire sa valeur qu’il suffira de soustraire pour avoir un bien meilleur "zero" comme valeur de référence.. j’ai lu dans mes recherches que pour un maximum "stable" il valait mieux utiliser un régulateur du genre 3.0v appliqué sur "Vref" (avec un Arduino sur 5v, on utilise le 3.3v déjà disponible pour faire la même chose pour le même problème de bruit)..je pense que le fabricant gagnerait à avoir de la compatibilité avec Arduino pour faciliter l’accès à cette grande communauté de ”potentiels acheteurs", ce kit est franchement élégant et intéressant.. et tout fonctionne..

It works, but you really need to be prepared to put a lot of effort in to make it useful. They do not provide any useful documentation

Does it work? We will never know.The github demo software assumes one is programming the Pico with a Raspberry Pi. I don't have a Raspberry Pi, I only have the Pico and a Windows PC. The Amazon listing does not inform the buyer of this caveat. I'm dead in the water. Very very disappointing.Direct quote from the github site:"Install Pico-SDK in Raspberry Pi Assume that you are using Raspberry Pi OS 64bit (Bullseye) as operating system on Raspberry Pi. Here we are using Raspberry Pi 4B as PC to compile the project."
