Re: Hardware Watchdog Reboots

This one has capacitors (large and small) fitted to the +5V and +3.3V power rails.

First of all - you can't use two normal 5mm LEDs in series (driven from the Wemos +3.3V line) as the forward voltage drop across each LED is approx 1.8V.

The ESP8266 and Wemos D1 Mini are +3V3 devices - so please don't connect +5V to them. You can use a transistor to buffer the ESP8266 to the 5V LEDs or even a relay or a level shifter. Small single LEDs normally run off of 1.6V, so you could think about having two in series with a suitable current li...

Yes - I would use a 330uF or 470uF with a 0.1uF (or 100nF) in parallel.

The large capacitor acts as smoothing capacitor whilst the small one should deal with any nasty spikes on the PSU rail.

I have an ESP-01S (on a breadboard) that runs off of an USB power adapter type HW-131.
This device would only manage 20 or so minutes of up-time before it rebooted.

I've just added a 470uF and 100nF to the breadboard, so it will be interesting to see how long it stays UP.
