MPU6050 Low Power Mode

by tychodin on Thu Jan 20, 2022 10:47 pm

hey all, so i'm able to put the adafruit MPU6050 module into low power mode in circuitpython via

Code: Select all | TOGGLE FULL SIZE
mpu.sleep = True


but the led on the chip stays on, and draws something like 1.5mA. is there any way through the circuitpython mpu library to access that green led and shut it off? the readthedocs page suggests not, but maybe someone knows a backdoor to it?

The green LED is tied directly to power: https://learn.adafruit.com/mpu6050-6-do ... /downloads So, there is no way to turn it off programmatically from the sensor side of things.

Some of the newest feathers do allow you to disable StemmaQT power. The ESP32-S2 feathers do I believe. https://www.adafruit.com/product/5300
