Customer:
I have a new NULA board similar to dasduino. I couldn’t find the KiCAD project for the NULA board on your GitHub. I’m interested in which are the SCL and SDA pins for EasyC on the standard headers I soldered, since I don’t have EasyC available, but I want to read from the accelerometer via EasyC.

kupio sam od vas novu NULA pločicu (sličnu kao dasduino). Nisam mogao na vašem GitHubu pronaći kicad projekt od NULA boarda koji sam dobio. Zapravo me zanima koji su SCL i SDA pinovi za EasyC na ovim standardnim headerima koje sam zalemio pošto nemam easyC, a želim preko EasyC čitati s akcelerometra.

The hardware design files are being restructured and should be published soon. If you specify which NULA board you have, I can send you the KiCAD files. In the meantime, here are the schematics for all 3 NULA boards.
The I2C pins are:
NULA Max: SDA = 8, SCL = 9
NULA Mini: SDA = 6, SCL = 7
NULA DeepSleep: SDA = 8, SCL = 9

Ispričavamo se na nedostatku hardverskih datoteka, trenutno restrukturiramo cijeli proces njihovog objavljivanja te će oni biti postavljeni vjerojatno početkom veljače. Ako navedete točno koju NULA ploču imate, mogu Vam proslijediti kiCAD fileove. U međuvremenu Vam proslijeđujem Shemu za sve 3 NULA pločice. Što se tiče I2C pinova:
NULA Max: SDA = 8 , SCL = 9 NULA Mini: SDA = 6, SCL = 7 NULA DeepSleep: SDA = 8, SCL = 9
