I will try the " craft approach ". The LED driver does not provide stable 12V, as it can be between 12 to 14.5V in a camper. And with your recommendations for diode and capacitor.
Hi @dmshimself
available pins are:
G21, G25 - on the right - first and second pin from the top
G26, G32 - at the bottom - third and fourth pin from the left
Please note: non of the above pins can drive 5 V; they are (as are all ESP32 GPIO pins) 3.3 V only.
Thanks

Hi Paopao,
I am in your same situation, I have been trying to communicate UHF-RFID-UNIT with Aton Lite and I don't know the right code.
Could you spend the code to start my project?
Thank you
Hello @Otofoto
are the aforementioned 25 minutes from a fully charged TailBat? That seems a bit short.
I've measured the power consumption of the Atom GPS kit (w/o sd card) and it takes about 100 mA. So it should not suffer from a premature shutdown due to consuming too little power as the shutdown current limit in the TailBat is about 45 mA.
The TailBat has a 190 mAh battery - so theoretically you should get close to 2 hours out of it.
Thanks
Felix
Hello @sgu
it looks like ATOM GPS is broken in current UIFlow. It doesn't work for me either.
That said, I found that I can use the GPS unit blocks instead (with default custom GPIOs).
Thanks
Felix
@holofloh Ahh, thank you! I think I understand a little better now. I think I misunderstood exactly what an access point was supposed to do. I'll try your suggestions and let you know how it works.
Thanks again!

New CH552 firmware for Short-Wifi-Issue of M5Atom/Stick/TimerCAM/etc. : About 9 months ago
Many thanks to you for all the advice! I was indeed using a servo way too powerful for the atom. My mistake, I've learnt something :)
All the best to you
Hello @RolfF
It's a design mistake.
It is a basic mistake to add 5V to 3.3V system.
5V enters the RF circuit, causing deterioration or damage.
There are many cases where ATOM has already broken.
