Croduino NOVA2 USB connector damaged - alternative programming methods

Soldered_Bot · December 9, 2018, 1:03pm

Customer:

I have a Croduino NOVA2 and managed to break off the USB connector. Is there a way to connect it to USB for flashing without the connector, or is there another flashing method that doesn’t require USB?

Alternatively, can you provide the schematic so I can try to resolder the connector?

imam jedan primjerak vaseg nova2 i uspio sam mu odvaliti usb konektor. → https://i.imgur.com/ytjaB9L.jpg

Moje pitanje je, ima li neka caka da ga spojim na usb radi flasha mimo konektora ili ima pak opet neka druga caka za flash bez usba.

Alternativno, mozete li mi poslati taj komad scheme da probam nanovo zalemiti konektor gore?

P.S. nemoj drzati u ladici novu ukopcanu na kabel i kopati po ladici…

Hvala,

G.

Soldered Support:

The schematic for Croduino NOVA2 is available here: Croduino-NOVA-Eagle-Files/v1.2/Croduino Nova v1.2.pdf at master · SolderedElectronics/Croduino-NOVA-Eagle-Files · GitHub

If you have a small and precise soldering iron, you should be able to repair this. What you need to do is:

connect power (+5V and GND, can go to pins)
connect the pins for USB programming (D+ and D-). For this you will need to download the Eagle files: Croduino-NOVA-Eagle-Files/v1.2 at master · SolderedElectronics/Croduino-NOVA-Eagle-Files · GitHub and find the traces going to the D+ and D- lines
or, if this image helps: https://imgur.com/a/oMfeDrj - all D+ and D- line locations are marked. Since they are broken off at the USB connector, you will need to connect somehow to the chip. After that you can program normally again.

If this seems inconvenient, plan B is to get an external USB to UART adapter, such as one with CP2102. Connect it directly to the Croduino pins and program as if you have a miniNOVA: https://e-radionica.com/hr/blog/2018/01/14/kako-programirati-croduino-mininova-iz-arduino-ide/ - the only difference is you don’t have the GPIO0 button which you need for reset, so you simply connect GPIO0 to reset with a wire before you press the upload button in Arduino IDE.

Hopefully one of these two options will work for you!

baš mi žao zbog toga što se dogodilo! Zapamtit ćemo savjet

Ovdje je shema za Croduino NOVA2:
Croduino-NOVA-Eagle-Files/v1.2/Croduino Nova v1.2.pdf at master · SolderedElectronics/Croduino-NOVA-Eagle-Files · GitHub

Ako imaš neku malu i preciznu lemilicu, ovo ćeš moći popraviti. Ono što trebaš napraviti je:

spojiti napajanje (+5V i gnd, može na pinove)
spojiti pinove za programiranje preko USB-a(D+ i D-). Za to ćeš morati skinuti Eagle datoteke: Croduino-NOVA-Eagle-Files/v1.2 at master · SolderedElectronics/Croduino-NOVA-Eagle-Files · GitHub
i pronaći vodove koji idu na D+ i D- linije
ili, ako će ova slika pomoći: https://imgur.com/a/oMfeDrj
označena su sva mjesta D+ i D- linija. Budući da su otkinuta na USB konektoru morat ćeš se nekako spojiti na chipu. Nakon toga možeš opet normalno programirati.

Ako ti se ovo čini nezgodno, plan B je uzeti eksterni USB na UART adapter, kao npr.: Soldered: Open-Source Electronics, Boards, Sensors & Modules – Soldered Electronics
njega spojiš direktno na pinove Croduina i programiraš kao da imaš miniNOVA: https://e-radionica.com/hr/blog/2018/01/14/kako-programirati-croduino-mininova-iz-arduino-ide/
jedino što nemaš GPIO0 tipku koja ti treba za reset, pa u samo s kablićem spojiš GPIO0 na reset prije nego stisneš tipku upload u Arduino IDE.

Nadam se da će neka od dvije opcije odgovarati! Jel to mogu, još za kraj, zamoliti da postaviš ovo isto pitanje na naš forum: http://forum.e-radionica.com/hr/
to će nam pomoći da više ljudi vidi rješenje ovoga problema i brže ga može riješiti.
