Customer:
I’ve had Croduino miniNOVA2 boards for some time and now want to use them for projects. However, I can’t find any information or datasheet for the product online. I have no problem with ESP8266, but for this specific board I need to know: the pinout (some pins are unmarked), how to use the easyC connector (what is it for), the wiring for the power connector, and the orientation of the connector with markings I received with the product.
I also bought your NOVA programmer, but I need specifics on how to program this board:
-
How do I connect the NOVA programmer, and to which pins?
-
Do I connect external power to VIN during programming, and what voltage range is acceptable?
-
Since there are no RST and GPIO0 buttons on the miniNOVA2, how do I put it into programming mode?
Original message (Croatian)
kupio sam kod vas ima već neko vrijeme Croduino miniNOVA2 boardove, a sada bi ih htio i iskoristiti za projekte.
No, na netu nemogu nigdje naći informacije / datasheet o proizvodu. Za ESP8266 nemam problema, ali za ovo specifično me zanima “pinout” pločice (neki su neoznačeni), kako upotrebljavati easyC konektor (čemu bi služio), ožičenje za konektor napajanja, i orjentaciju ovog konektora s oznakama koji sam dobio s proizvodom.
Također sam kupio vaš NOVA programer, no zanimaju me specifičnosti kako programirati ovu pločicu:
-
kako spajam NOVA programer, na koje pinove?
-
dali spajam eksterno napajanje na VIN prilikom programiranja, i koji je raspon voltaže napajanja prihvatljiv?
-
s obzirom da ne postoje RST i GPIO0 tipke na miniNOVA2, kako da ga stavim u mod za programiranje?
Hvala,

Soldered Support:
The pins on the right side are intended for the small NOVA programmer. The EasyC connector is for our breakout boards that use easyC, which is essentially I2C over a small cable, making complex components simpler to connect.
The NOVA programmer is not necessary on this board because it has a USB header and can be programmed over USB using the ESP8266 board definition.
If you want to use the NOVA programmer, it connects to the SPI pins MISO/MOSI/SCK as marked, along with VCC and GND for power.
The voltage for powering this board is 3V3. There is a converted 5V on the board but it is recommended to power it on the 3V3 pin.
The board can be put into BOOT mode by connecting GPIO0 → GND.

evo odgovora, ovo je pinout koji sam dobio od svojih kolega koji su dizajnirali

EasyC konektor je konektor za naše breakout pločice koje koriste easyC- što je u suštini I2C preko malog kablića - čineći kompleksnije komponente jednostavnijim za spojiti. Više možete saznati ovdje Konektor napajanja ne mogu vidjeti iz starijih datoteka dizajna pločice a ne vidim da ih imamo u uredu. Imate li multimetar? Tako možete naći koji pin je GND.
NOVA programer nije potreban na toj pločici jer ima USB header i može se programirati preko USB-a koristeći ESP8266 board definition.
Ako želite koristiti NOVA programer, on se spaja na SPI pinove MISO/MOSI/SCK kao što su označeni ovdje, naravno uz VCC i GND s napajanjem.
Napon s kojim se napaja ova pločica je 3V3. Ima konvertiranih 5V na pločici ali preporuča se da se napaja na 3v3 pin.
Ako se ne varam ta pločica se može staviti u ‘BOOT’ mode ako se spoji GPIO0 → GND.
Nadam se da ovo pomaže, ako imate dodatnih pitanja javite.

Customer:
Thank you for the quick response. However, this is not the board I have. I should attach photos of everything I received.
The easyC and power information is clear, thank you. I assume BOOT is the same for all ESP8266 boards and I’ll investigate that. I just need the pinout for this board from the photo one more time, specifically for the connectors on the right side. I also received this female connector with it, but I assume the markings don’t mean anything and were already on the connector. Can you confirm? Finally, is the connect programmer equivalent to the NOVA programmer? Do they have the same pinout? Can I use either one? I assume this NOVA board also has a matching pinout on the right side for these programmers, but I’d like you to confirm that and confirm the orientation (which pin is GND).
I bought these boards from you when they were on sale and discontinued (when you were transitioning from croduino to soldered), so I couldn’t find information on them anywhere else.

hvala lijepo na brzom odgovoru.
No, to nije pločica koju imam; najbolje da pridružim fotografije svega što sam dobio.
Za easyC i napajanje mi je jasno, hvala lijepo. Pretpostavljam da ‘BOOT’ je isti za sve ESP8266 pa ću to istražiti.
Samo molim vas još jednom pinout za ovu pločicu s fotografije? Specifično za ove spojeve s desne strane. Uz nju sam dobio i ovaj “ženski” konektor ali pretpostavljam da oznake ništa ne znače nego su bile već na konektoru - možete li to potvrditi? I na kraju, jeli connect programmer ekvivalentan nova programeru, dali je isti pinout/mogu li koristiti bilo koji od njih dva? Pretpostavljam da je na ovoj nova pločici isto matching pinout s desne strane za ove programatore, ali volio bi da mi to potvrdite, i da mi potvrdite “orijentaciju” (koji je pin GND).
Ove pločice sam kupio kod vas kad je bila na rasprodaji i discontinued (tada ste prelazili s croduino na soldered), pa više nisam mogao naći nigdje info o njoj.
Hvala lijepo, [name removed] Drašković

The pins on the right side are intended for the small NOVA programmer. The circled pin is GND, so orient it that way. When you connect the female header pins and then insert the NOVA programmer so that GND is on the circled pin, you’ll be able to program the ESP8266.
The Connect programmer is an updated version of the NOVA programmer (it has USB-C and a different IC for programming) and should work equivalently.

super što si poslao sliku, ti pinovi s desne strane su namijenjeni upravo za taj mali nova programer, ovaj zaokruženi je GND pa se tako orjentiraj. Kad spojiš ženske header pinove i onda utakneš NOVA programer tako da je GND na zaokruženom pinu, moći ćeš programirati ESP8266.
Connect programer je updateana verzija NOVA programera (ima USB-C i drugačiji IC za programiranje) pa bi trebali raditi ekvivalentno.
