Customer:
We need several pieces of information about programming and configuring your module. We need detailed instructions for setting up the Arduino IDE for this board, device configuration, etc., because we can’t manage to program this module - we constantly get errors when trying to upload code. We followed the instructions on your website, but they were for a slightly different module (NOVA 2), so that may be why we couldn’t get it working.
Also, do you have a LoRa module available for this board? If so, please provide instructions for connecting a LoRa module to it.

Trebamo nekoliko informacija vezano za programiranje i konfiguraciju vašeg modula .-molim detaljne upute za podešavanje arduino ide aplikacije vezano za ploču, uređaj i sl jer nikako ne uspijevamo isprogramirati ovaj modul, konstantno nam izbacuje error prilikom pokušaja ubacivanja koda.Sve smo radili prema uputama sa vaše stranice ali su upute za malo drugačiji modul (nova 2) pa možda zato nismo uspjeli to odraditi.

Based on the image, you have the first version of the Croduino NOVA board. The difference between Croduino NOVA and Croduino NOVA2 is in the USB-UART converter used, and I would say that’s the main problem. It would definitely be useful if you copied the error you’re getting and sent it to us so we can see what the problem is and fix it faster. You can try installing the driver for CP2102 USB-UART and then attempt to transfer code to the board according to the instructions. If that doesn’t work either, send a screenshot of the tools menu from Arduino IDE and the error you get when uploading code.
We currently don’t have LoRa modules in our product range.

Koliko vidim prema slici imate prvu verziju pločice Croduino NOVA. Razlika između Croduino NOVA i Croduino NOVA2 je u USB-UART konverteru koji se koristi i rekao bi da je tu glavni problem. Svakako bi bilo korisno da kopirate grešku koju dobijete te nam pošaljete kako bi vidjeli što je problem te ga brže otklonili. Možete probati instalirati driver za CP2102 USB-UART te onda prema pokušati prebaciti kod na pločicu prema uputama, ako niti onda ne bude radilo pošaljite sliku tools izbornika iz Arduino IDE i grešku koju dobijete prilikom uploada koda.

I managed to set up the board and program test content. What interests me is whether a microphone and headphones can be connected to this device so I can hear sound with amplification in real time through the headphones. Do you have the components needed to build such a device?
Original message (Croatian)
Zahvaljujem na odgovoru sve riješeno uspio sam podesiti ploču i isprogramirati testni sadržaj. Ono što me interesira dali se na navedeni uređaj može spojiti mikrofon i slušalice kako bih u realnom vremenu čuo zvuk sa pojačanjem na slušalicama, imate li komponente potrebne za gradnju takvog uređaja?

A microphone and headphones can be connected to the Croduino NOVA, but the quality is questionable. This board doesn’t have 2 I2S interfaces that could be used to connect headphones and a microphone. The remaining option is to connect the headphones via analog pins, but the quality is questionable and you would need to use DMA to achieve a slightly higher sampling rate. The documentation for ADC is at Log in - Read the Docs Business where you can see what’s available.
Another option is to use a board with an ESP32 microcontroller that has 2 I2S interfaces so you can connect a microphone and headphones via separate interfaces (of course via appropriate breakouts which we unfortunately don’t have in our product range). For this microcontroller, official documentation and support for the I2S interface is quite poor, so you would have to do a lot of testing until everything works. Also, this won’t be real-time, because you need to take a certain amount of samples, then store them and then send them to the headphones, so there would be latency. If you only need to amplify the sound, it’s better to use an analog amplifier.

Odlično da ste uspjeli isprogramirati pločicu. Na Croduino NOVA se može spojiti mikrofon i slušalice, ali je kvaliteta upitna. Navedena pločica nema 2 I2S sučelja na koja i se moglo spojiti slušalice i mikrofon. Opcija koja ostaje da se slušalice spoje preko analognih pinova, ali tu je upitna kvaliteta te se za to mora koristiti DMA da se uspije dobiti malo veću brzinu sampliranja. Na linku Log in - Read the Docs Business je dokumentacija za ADC te možete pogledati što je tu navedeno. Za ovaj mikrokontroler službena dokumentacija i podrška za I2S sučelje je dosta loša tako da bi morali dosta sami isprobavati dok sve ne proradi. Također, to neće ništa biti u realnome vremenu, jer se mora uzeti određena količina sampleova, zatim ih spremiti i onda poslati na slušalice, dakle postojala bi latencija. Ako je potrebno samo pojačati zvuk onda je bolje koristiti analogno pojačalo.
