D1 mini, TP4056 and solar panel

Can anyone offer any insight into why my project to solar power a Wemos D1 mini might not be working? I am trying to build a wireless soil moisture sensor which runs fine when

Parallel tp 4056 for powering Wemos

i would like to power Wemos D1 mini with solar panel and two 18650 batteries. I was thinking to wire two TP4056 parallel (each charge their own battery) and with OUT pins

Solar Power – the Wemos D1 and 12/24v Battery Chargers

My D1 Minis came earlier this week, the power modules arrived this morning and all I needed were some simple resistor divider pairs so that I could easily build a pair of totally

Problem with a battery (and solar) powered Wemos D1 Mini

The WeMos D1 mini has AFAIK a better LDO with 125mV dropout at 100mA (ME6211). Did you try without the external regulator, with +batt connected to the 5volt pin.

6 FAQs about [Wemos d1 mini solar power]

What is a WEMOS D1 mini Pro?

The Wemos D1 Mini Pro has a small form-factor and a wide range of plug-and-play shields make it an ideal solution for quickly getting started with programming the ESP8266 SoC. It is an inexpensive way to build the Internet Of Things ( IoT ) and is Arduino compatible. My Book : DIY Off-Grid Solar Power for Everyone

How to save power on WEMOS D1 mini?

More Power Saving Option : The Wemos D1 Mini has a small LED that lights when the board is powered. It consumes a lot of power. So just pull that LED off the board with a pair of pliers. It will drastically drop the sleep current down. Now the device can run for a long time with a single Li-Ion battery. // Go to the Project Settings (nut icon).

Does a WEMOS D1 mini work with 125 MV dropout?

The WeMos D1 mini has AFAIK a better LDO with 125mV dropout at 100mA (ME6211). Did you try without the external regulator, with +batt connected to the 5volt pin. (and measure the dropout) Why change the supervisor voltage (200 ohm + 1k). The WeMos should work fine from 3volt. The 6k8 gate resistor could make the fet unstable.

Does a WEMOS D1 mini turn a servo?

Essentially I have a Wemos D1 mini that turns a servo when it's issued a command on the network. The Wemos needs to be powered 24x7x365 but the servo only powers up when it needs to turn (3-4 times a day max). I did a bunch of measurements today and here is what I have found. I am using this USB digital Multimeter to get my current readings below.

Can a solar panel power a WEMOS?

The servo control cable is then connected to the Wemos. I connected the solar panel to the charge port on the battery pack. Using grid power I can confirm that the battery pack will charge while also running the Wemos / servo. So in theory a solar panel should accomplish the same task. I am able to power the Wemos with only the solar panel.

Can a solar panel charge a D1 mini?

My solar panel is 5.5v 0.6W, same diode and charging module. I have a 10,000 mAh 18650 battery rather than a 14500. If I charge the battery via a USB charger, it works well for a couple of days. However once the battery is low, it can not power up the D1 mini.
