There was an interesting recent ADAfruit video where they were using arduino and an external super low power timer chip ( TPL5110) to wake up the arduino at a set interval, let it's do it's thing, then when it's done the arduino was giving a signal back to the chip which would then cut power to the ...

I remember reading in another thread that with a static IP it's between 2 and 3 sec, with dhcp it's about 4. Is there a command to run to check when you're on the network? I've got a built in 5 sec delay in my projects before connecting to the MQTT broker, but I'd like to replace that with something...

Here's My first script! It sends a MQTT signal when a button is pressed. It's set up to have 3 buttons, the button callback only sets a global variable. Then the main loop checks if that variable is set and sends the command. This means that slow network code stays out of the callback, makes sure th...

Thank you so much for your help. I'm going to blame buying the cheapest D1 minis I could find on Ebay. Connecting it to a solid 3.3v source seems to work fine, I'm able to connect to it's default Wifi and ping it endlessly (I count 3 min as endless based on what I was getting earlier.) Until my USB2...

What you can try is deactivating the network: import network network.WLAN(network.STA_AP).active(False) network.WLAN(network.STA_IF).active(False) It's strange I'd be getting a short on both boards, They're dangling in free air off the cable (I've tried switching cables too) I get this running the ...

[quote="deshipu"]Is any part of the board getting hot? In particular, the 3-pin black voltage regulator?[/quote]

Yes the chip beside the USB connection does get hot, I think it's the same one you're mentioning, 3 pins one side, 2 on the other.

Update with more info. Turns out the board isn't crashing, when I connect with screen, It stops, but I can connect again just fine. I wrote the firmware to the board again with --verify, That reported it was all fine. I wrote it at baud 9600 which took a while but strangely (as you will see soon) it...

Hi there. I'm reasonably new to Micropython but have made one project using a nodeMCU and some buttons connected to MQTT I've received a couple of Wemos D1 mini's and I'm having trouble with them. I've flashed them with the same firmware used on the nodeMCU (the latest download for esp8266) and when...
