Try the following steps:

uci set onion.console.setup=1
uci set onion.console.install=1
uci commit onion
console-install-tool

Thanks to everyone for the answers and interesting stories! I solved my problem by applying the DS-DS converter LM2596.

Hello. Tell, please, how I can power my Omega2 from 3.7 volts? I know, exist board Power Dock, but I need compact solution.

@Lex-Slaghuis
The installer has installed everything correctly. It is so specifically conceived that when entering on 192.168.3.1, Onion OS was opened because Onion console is not installed in new Omega2 during installation. To fix this, you may need to edit the file /www/index.html

Hey. An update was recently released in which Onion added support for all Python2 modules for Python3: https://onion.io/2bt-python3-modules/
Try to enter

opkg install python3-onioni2c

Hey. I am very glad that this event happened! I hope that developers will more often tell us such wonderful news!

How I can install library onionI2C for Python3?

1. Is the pinout diagram from Оmega-2 suitable for Omega-2 +?
   

2. Can I use pins 6, 7, 8, 9 as GPIO?

3. Is there an Onion Gpio library for Python 3?

Thanks in advance for answers

The model is made in cubesat 1u format. Functions performed:

1. Collecting data from sensors (temperature, pressure, humidity, acceleration along three axes, battery voltage, GPS data) and sending them over the radio channel.
2. Single-axis orientation along the vertical axis using the reaction wheel. Fuzzy logic is used to set the angular velocity of the reaction wheel.
   Demonstration
   If you have any questions, I will be happy to answer them.

@crispyoz I am connecting Omega-2 + via a homemade board (3.3v to vin). Now I connected it to Power dock 2. The metal cover is also very hot (burns finger). I remember that some time ago I could safely touch the lid for a long time. Current consumption approx. 500 mA

I noticed that my Omega2 immediately after switching on heats up to 60 degrees Celsius (metal cover). Don't touch it. Is this the norm? It seems to me that it was less hot before.

Recently, when starting an application that reads information from a microSD card, an error occurs

FAT-fs (mmcblk0p1): error, fat_get_cluster: invalid cluster chain (i_pos 528133)

@David-Kerr
First I'm running from a 3.7V cell, and then trying a 5V power supply. I use TO220 with no heatsink. After several measurements, I noticed that the output of the LM3940 has 3.28V without load. When I connect Omega, the voltage drops to 3.1V, which is not enough for Omega.

Try the following steps:

uci set onion.console.setup=1
uci set onion.console.install=1
uci commit onion
console-install-tool

@David-Kerr
I bought an LM3940, put an output capacitor with a capacity of 220 microfarads, but Omega does not start even with an input voltage of 5 volts. The orange LED starts flashing, but turns off after a few seconds.
