Hi everyone !
I am working at a project including the interfacing between RF module MRF24J40 and Arduino Uno v3.
But i have a problem : Arduino board works with 5v and RF module with 3.3v.
I need a auxiliary board which converts 5v to 3.3v. I read from the internet and it seems i need a level shiftter (i bought 74LVC4245AD) and a LDO regulator 3.3V.
SPI configuration i founded from the internet.
I bought these components and i don't know how to make a link between them.
Can anyone help me ?
