ESP8266 Programmer is a breakout board to upload firmware on ESP8266. It benefits of USB-C connector, the new de-facto standard on the market.
It is designed to be attached to Lolin/Wemos D1 mini shield. If you are not going to use this form factor, you can break the external frame, gaining some mm^2 ([video](https://youtu.be/vi9zZSLOqzo)). Despite the name, it can be also used to program ESP32 an...
ESP8266 ESP-12 minimal stabilized circuit schematic and PCB
* Breadboard friendly headers and Wemos D1 mini pin numbers
* 0805 footprints for easy hand soldering
* Designed for battery operation:
Voltage regulator: Torex XC6220B331PR-G (8uA quiescent current, 1000mA max)
VIN: max. 6V
To enable self-wake from deep sleep, solder a 0 Ohm resistor over the WAKE pads
You can use a 0 Ohm instead of...
A simple ethernet shield for Wemos D1 Mini based on W5500 respecting WizNet directives (https://wizwiki.net/wiki/doku.php/products:w5500:start).
All SMD components are chosen such that JLCPCB can mount them. The only exception is the crystal; replace it with X322525MOB4SI (adapting both schematic and layout) if you want it mounted.
Since JLCPCB can mount either top or bottom only, all the SMD co...

Electric monitor energy viewing local datas through oled display and using remote monitoring with the Node Red's tools and sending datas to internet using IBM cloud and mqtt protocol.
The wemos mini is the heart of this project. The current readings are made with the non invasive current SCT013 30V/1A sensor, then the courrent measured is converted to a digital format using the ADS1115 module. It'...
Breakout Board for driving WS2812 LED strings from Wemos D1 Mini and External 5VDC Power Supply.
Includes 3.3 -> 5V Level Shifter on D4/GPIO2 for WLED software compatability.
+5VDC and GND are on copper areas to maximize current availability for LED strips
# Simple yet powerfull!
This board provides solid connection between Wemos D1 mini (ESP8266) and 2.4" TFT ILI9341 XPT2046 SPI Display (TJCTM24024-SPI). The main goal is to build cheap wi-fi enabled display with touch interface for use in various IoT projects. Display communicates with ESP8266 via SPI (di...
A simple weather station with 2 separated units, indoor and outdoor, which send measurements to Thingspeak (one channel).
Indoor unit consists of arduino uno with w5100 ethernet shield and a dht11 sensor.
Outdoor unit consists of wemos d1 mini, AM2302 (dht22) and a BMP180.
