Pro Micro with Atmega32U4 chip Development Board, AYWHP 1 PCS Pro Micro 5V/16MHz Nano microcontroller Development Board with Built-in USB updater Type-C Interface Compatible with Arduino IDE

Arrived quickly and worked great with my custom keyboard build that I'm typing this review on. The 3 pack is a great value so I'll be keeping a couple of these around for sure.

If these are not working for you I can almost 100% bet your USB cable (while might be the right fit) isn’t wired to transfer data. A lot of USB C cables only have internal wiring to charge a device not transfer data. Ensure you have one that transfers data. I used my iPhone and pc to see which cables charged only vs which ones allowed my phone to be recognized by my pc. If this saves you the 72 hours of chatbot he’ll I went through then good. Tried everything under the sun based on copilot for 3 days then finally decided to grab my phone and plug it in and realized my cable was not a data cable. Found one that was and bam I’m in business. If you don’t have anything to test with here’s what you should expect with a bad cable on micro: solid red led to the upper left of the chip that gives no feedback no matter what you do. A good cable: same thing but LED3 by pin 7 will blink once when plugged in. Also, your port will see the micro as a Leonardo if the cable is correct.

On 3/3 of these boards I got, each USB c port had an issue. Using a known good cable, each cable becomes "stuck" in these boards, leading to the pins inside the USB c port breaking (at the far right). The PCB itself seems to be decent quality. Hard to say if I just happened to get 3 boards of a bad run or what.

Built a hand wired mechanical keyboard with it. Everything worked and was easy to program.

Good little mcu but do note that this does have less available pins than the genuine Arduino micro. The actual processor has some decent specs as far as micro controllers go, but there are some more modern options that do give a bit more performance with more GPIO like the RP2040. It has a usb interface built in so it can be used for HID projects or the like. It is pretty easy to use, you can just use platform up or Arduino ide. Its value is not bad but you can find a lot of micro controllers with similar or better specs for the same price and it is moderately quick definetly not the fastest.

These are very nice quality and 3 of 3 worked fine. These have the USB-C connector. Just what I needed.

I ordered these for the value and availability. Got my project done on time. I did manage to brick two boards, but it was my fault for rushing and shorting them out.

I've bought 40 of this specific brand. The version with the blue PCB works great. The version with the black PCB is terrible. USB malfunctions constantly, something is systemically wrong with that version. Don't know if the company got a different supplier or what.

Scheda Pro Micro con chip ATmega32u4 che svolge perfettamente il suo lavoro. Arrivata funzionante, viene riconosciuta correttamente dal PC ed è compatibile con l’IDE Arduino senza particolari problemi. La frequenza 5 V / 16 MHz è ideale per la maggior parte dei progetti DIY, tastiere custom, HID e piccoli prototipi. Dimensioni compatte, pin ben esposti e qualità costruttiva adeguata al prezzo. Ottima soluzione per chi cerca una Pro Micro economica ma affidabile, soprattutto per progetti dove lo spazio è ridotto. Consigliata a chi ha un minimo di esperienza con Arduino e microcontrollori.

Funktioniert einwandfrei, klare Kauf Empfehlung

so richtig funktionieren die Teile nicht, beim Einstecken an USB leuchten RX und TX oder nur RX oder TX oder keine LED. Ein Bootloader ist nicht drauf, also kein Flashen über USB. Hardwareerkennung sagt: [Jul10 17:43] usb 3-1: new full-speed USB device number 5 using xhci_hcd [ +10,501738] xhci_hcd 0000:03:00.4: xHCI host not responding to stop endpoint command [ +0,000973] xhci_hcd 0000:03:00.4: xHCI host controller not responding, assume dead [ +0,000000] xhci_hcd 0000:03:00.4: HC died; cleaning up [ +0,014930] usb 3-1: unable to read config index 0 descriptor/all [ +0,000004] usb 3-1: can't read configurations, error -110 [ +0,000052] usb usb3-port1: couldn't allocate usb_device [ +0,000009] usb 3-3: USB disconnect, device number 2 [ +0,000335] usb 3-4: USB disconnect, device number 3 Danach ist der USB-Anschluß tot und erst nach PC-Rebbot wieder nutzbar, Flashen über ISP funktioniert auch nicht -> falscher Chiptyp. Keine Ahnung, was das ist, gingen alle zurück

fait son job pour bricolage ludique

Ho letto le recensioni di altri utenti dove veniva indicato il non funzionamento, non so se abbiano utilizzato dei cavi usb c non compatibili o se effettivamente si sia trattato di un batch difettoso, ma le schede che ho ricevuto io sono perfettamente funzionanti con ide arduino, senza necessità di installare driver aggiuntivi, basta seguire le indicazioni. l'unico neo riscontrato è che sulla scheda non sia presente alcun pulsante di reset, è quindi necessario utilizzare uno swtich on/off a monte Per il momento posso consigliarne l'acquisto, in caso in futuro dovessi riscontrare qualche problema sarà mia premura modificare questo post. le stelle fornite sono basate sul mio utilizzo del prodotto, ma ho cercato di elencare sia i pregi che i difetti, in modo che possiate fare le vostre valutazioni PS: Questo articolo mi è stato fornito da Vine in cambio di una valutazione onesta
