The circuit and PCB have been produced and tested and basic code is available on github. See the project site on hackaday.io for more information about the project.
The ESP Programmer (V2) is the successor of [ESP8266 Programmer](https://easyeda.com/fabiano.riccardi/esp8266-programmer), a board to upload firmware on ESP8266, ESP32, and ESP32-S2. Like the predecessor, it benefits the USB-C connector, but it is improved replacing the CH340 with Silicon Labs CP2104 USB-serial converter (smaller footprint), adding 2 LEDs to show the status of RX and TX line and i...
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...
Shield for Wemos D1 Mini. It provides two 3.3V GPIO and two 5V GPIO each with supply voltage, and ground terminals.
The two 3.3V GPIO have provisions for optional pullup resistors. These can be used with sensors or 1-wire devices requiring pullup.
Two additional GPIO are for 5V devices with level shifters to provide 5V Input or Output that is compatible with 3.3V GPIO on the Wemos.
ESP12F based board with 4 relays, DHST and/or LM35 temperature sensor(s) for Local or remote temperature measurment. Sockets for clock based modules based on DS1307 or DS3221 clock chips for time tracking. Additional I2C ports provide expandability to I2C displays or other sensors.
Great platform for building web based switches and monitoring temperatures and other sensors and login with RTC chips...

2 relays WIFI commutation
just 1 strap for single face PCB
This board can be powered through differents kind of powers :
from the H1 connect a LIPO battery (deepsleep available shunt GPIO16 to RST pins)
from the H1 connector DC 3V3 directly (shunt in&out AMS1117 pins and use 3V3 relays)
from the H1 connector DC input from 5V to 15V (adapt the relays' voltage)
using a AC/DC power converter HLK-PM01...
