I'm working on designing a very minimal MicroMod carrier board consisting of only:
1. The Teensy 4 MicroMod
2. A 3.3V regulator
3. An MPU-9250 IMU
4. A 4-pin serial connection

I'm doing this to start gaining some experience with the Teensy 4 MicroMod format before working on more complex projects. Attached is a schematic.

Specific questions:
1. Do BATT_VIN, RTC_3V, or USB_VIN need to be connected to power?
2. Are there recommended de-coupling caps? I just have some generic ones in the schematic for now.

You do realise that the MPU-9259 went EOL by 12/31/2018. Apparently it was replaced by the ICM-20948.
