Thank you guys for the reply, I manage to update the firmware to 19.07.6 and then all package installation worked fine thru opkg. I have now a Omega 1 running with OpenVPN client, ser2net and 4G dongle.
Regards

I found a workaround for my serial connection, just put the microcontroller in deep sleep before trying to awake Omega, this is enough to let it boot correctly. Will not be opening a new thread with that.
Thanks

Well, you are correct, the extra heat seems to be because of the ams1117. I already had another mp1584 providing 3.3V to the same circuit, I just add a FET to switch it to omega to power on and now I'm under 50 degrees Celcius.
My problem now is that I found out that omega cannot have anything connected to TX1 while booting, will open another thread to get some help on that.
Thanks for the help.

Hi, I made my own dock circuit, and I'm powering it with an AMS1117, it works well, but it gets hot.
When using the expansion dock, the case of Omega2+ hits 43 degrees Celcius, but in my own circuit, it goes to 53 degrees.
Would the regulator be the reason for the heating up?
Any other detail that I may be missing on my design that is making it to get the extra 10 degrees?
Attached is the relevant circuit.

Hello, anybody had lucky on getting different sizes of oled to work with the available libraries, like oled-exp or pyOledExp?

@Lazar-Demin Thank you for the reply, I will make my own board with the LTE module and a usb hub in between them, add some sensors and a MPPT solar charger as well. Thank you

@bill Yes sir, I used this one: http://downloads.openwrt.org/releases/19.07.6/targets/ar71xx/generic/openwrt-19.07.6-ar71xx-generic-onion-omega-squashfs-sysupgrade.bin
It has been running, it's not on all the time, but every time that I connect I runs perfectly.
Before upgrading I had remove the Onion interface and added Luci, even did the upgrade thru the web interface.

Looking at the schematics I don't see anything between CPU and LTE module, so that answer my question. I will have to build my own module then.

Hello @jossvall, I didn’t doubt that the CPU offers, but the board doesn’t seems to, my guess is that the port is been used by the LTE module incorporated. If that is the case my solution would be making my own pcb adding a hub between CPU and LTE module, so I can add more devices.
Thanks for the input.

Thank you. The idea is to remote to a device over Serial, so this v1 board did the trick. But I'm looking in upgrading this, using the Omega2 LTE, but I was looking at the specs and it doesn't seems to offer the USB Host port, it's been used by the LTE module?
