Hi, I want your guys advice to ensure I have all of the theory behind the wiring understood before I accidentally put 5V through the SX1276 which runs at 3.3V.
I will be using a Arduino Nano with a SX1276 LoRa transceiver module, which uses SPI. https://www.ebay.com.au/itm/282921878129 https://www.semtech.com/uploads/documents/DS_SX1276-7-8-9_W_APP_V5.pdf
Im planning on powering it using the Nano's 3.3V output and running the logic through a 74LVC245 level converter, which is unidirectional. (available at my local store). http://www.ti.com/lit/ds/symlink/sn74lvc245a.pdf
From what I understand I only need to run logic through the converter when going from the Nano to the SX1276? So I only need to have MOSI, SS, SCK and Reset going through the level converter as MISO DIO0, DIO1 and GND direction is going to the Nano? Will going from a 3.3V logic to the Nano's 5V logic have any issues?
Is all the above correct or should it be refined/ changed?
Thanks for your time.
