@bstafford the on-board ADC of the ESP32 is notoriously inaccurate!

Finally got the notification today and put an order in.

I was tempted to order a heap of them, but given they are obviously in short supply I ordered a minimal qty so I hope others can get some too. They look fantastic!

gpio_pullup_en(GPIO_NUM_32);
Hasn't happened since.

@wwhite don’t know about circuit python but mainstream python can be installed using the Thonny IDE
I have 1.19 running on M5Stamps at the moment but you have to remember that Mainsteam MP won’t have the M5Stack specific libraries

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).

@akscj Yes, you can. (Atom doesn’t have a battery though, so it’s not “charging”)
