https://devzone.nordicsemi.com/f/nordic-q-a/75513/design-my-own-pcb-with-nrf52832I am willing to use nRF52832 chip in one of my project. But all the breakouts dont fit the size and I want to design my own PCB with i2C accelerometer. I only want to transmit the date getting from i2C to a connected bluetooth device.

You will additionally have to add the I2C module to free GPIOs. There is only one PCB layout example, so please use <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fref_circuitry.html&amp;anchor=pcb_guidelines">this as reference</a> and pay attention to the PCB guidelines for your PCB design.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
