Hi there,
According to this link, i need a logic converter when i connect the main board to the ADXL345 sensor module through SPI communication. Do I still need the logic converter if i am not connecting the sensor module to Arduinos? Instead connecting the module to http://www.dialog-semiconductor.com/pro … -kit-basic which is the DA14580 development board. I will be working with the power supply of a coin cell battery which is approximately 3V. Thanks guys, please advise on this matter.
