BNO055 is 9-DOF absolute orientation sensor with all the required math inside it:

• Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360° sphere
• Absolute Orientation (Quaternion, 100Hz) Four point quaternion output for more accurate data manipulation
• Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s
• Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
• Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
• Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
• Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
• Temperature (1Hz) Ambient temperature in degrees celsius

I would love to have a core module with this sensor.

Hello @m5stack, I'm facing the same problem reported by @felmue with Core 2 and GoPlus2. Are you working on this bug?

@nzmillsto Esp32-S2 can do it but ESP32 can not

I would like to use the Thermal Unit in UIFlow (1.7.6) but in the unit selection dialog is always disabled. Take a look at the following picture.

I tried with a StickC, StickC Plus and a Core2 but UIFlow doesn't let me add the Thermal unit.

I have too experimented powering both Atom Lite and the Atom Matrix via the groove connector or via the headers pins and I noticed a weird thing. If the voltage is a little below 5V, for example 4.6 or 4.7 Volts it works fine. If the voltage is a little above 5V, for example 5.2V it power up but it never connect to internet.

I'm trying to use the lvgl canvas on the Core2 with UIFlow V1.7.4.
I'm using the following test program:

import lvgl as lv

lv.init()

scr = lv.obj()
cv = lv.canvas(scr, None)

lv.load_scr(lv)

but when it try to create the canvas it raise the following error:
'NoneType' object has no attributes'__deference__'

Can anyone help me?

I tried in many way but without any success, the UnitV is never able to read a QR. I think that is a firmaware bug. Can some one at @m5stack look at this?

@m5stack Can someone please answer or point me to some documentation?

@marcvl on the Core2 the widgets are implemented trough LVGL. For the alignments flags you can look at this page:
