ESP8266 Sensor Board
This is a battery powered sensor board based on the ESP8266 (ESP-12F).
By using a TPL5111 chip the battery consumption can be reduced to about 1µA when the ESP is not enabled. When the TPL5111 chip receives 5V at it's wake up pin this will turn the ESP on by enabling the 3.3V voltage regulator. At this moment you can run any program you want. If you want to turn the ESP off again you have to drive...
Esp Oven
A fully featured board based on ESP8266 and MAX31855 probe for managing temperature of electric ovens either by on-off or by pid control. The board supports 2 independent temperature probes and up to 2 relais for heating output. All the user operation is performed by a CGI web user interface provided by ESP8266 webserver and can be called by any standard html client like a webpage, a mobile or tab...
ESP8266 Mini Weather Station
A Mini weather station based on ESP-12. Include a BME280 or BME680 sensor chip on board, one or more DS18B20 onewire sensors. It's powered by a Lithium cell, can be for short time directly charged over present voltage input. A LDO with very low Iq included. Comes with voltage measurement for the connected battery. Hardware jumper for deep-sleep and a programming connector (charge the battery if +5...
ESP8266 RGB LED-Controller
A ESP-12 IoT controller for RGB LED Stripe 5-12V.
3+1 channels through MOSFET, PWM and dimming functionality.
The MOSFETs can be replaced by NPN Power transistors (input resistors are as THT parts placed, the 10k pull down's not needed.
The 4th channel is a Logic level up-converter (3.3V->5V). Driven by a 2N7002, can be replaced with BSS138 or similar. Note that it's is a very small power output...

Still working on it.. All data is raw and is interpreted in php for web.
UbiModem - Wifi Modem with ESP8266 - ESP-01
**[PROTOTYPE YET]**
# Wifi Modem ESP8266 - ESP-01 #
**for Retro Computer**
Simulates the old-style Hayes "AT" commands, so that the ESP8266 appears to the terminal as if it were a Hayes modem. These "AT" commands may then be issued to the ESP8266 in order to force it to connect to a wireless access point, and from there to make one or more manageable connections to the internet. It also includes...
