Hi everyone, Im looking to add a user button to my RAK19003. I have added these to 19007 but I don’t see the AIN1 pin on the 19003. Does this board use a different pin? Can I use a user button on a 19003?

Thanks

Hi @tmperez ,

If you only need a button you can use the UART or I2C pins. There is a limited space on the mini baseboard so few pins are exposed.

Awesome thank you for the reply.

It is not recommended to use SDA/SCL BOOT or UART
• Pressing the button on SDA/SCL will cause a “short to ground” on I2C, and if you connect something there later, it will look like a broken bus (stuck I2C).
• Also, don’t use BOOT or UART pins, because you can block boot/flash or serial communication.

So what is the truth?
