ESPEverythyng 885
Quote from Andy on June 21, 2016, 10:16 amWe are happy to present the ESPEverythyng 885 board. This effort is a culmination of several needs we personally had as well as needs expressed by others.
The NODEMCU development board is nice and all, but it's a bit klunky. It needs to go on a breadboard or other purpose built board to gain access to the GPIO's. Some GPIO's shouldn't be used, yet access to them is granted. There's no onboard signal conditioning.
We've built a board that keeps the ESP8266 and USB communication sections and then went a different direction. This board offers a I2C MCP23017 for 8 channels of digital input and 8 relay channels. There is an ADS1115 offering four channels of analog input, and a single channel goes straight to the Tout pin on the ESP2966. All five analog channels have customizable active filtering and scaling front ends.
There are provisions for connecting directly on the board or remotely with wires a DHT11/22 or DS18B20 one wire sensors.
Finally, there's a development area where a user is free to build whatever kind of circuitry they want to complete their customizations.
It really is a do-it-all board. I'm using it to control my pool. Currently I'm measuring water temperature, water pressure, air temperature and humidity. In the coming months I'll add an ORP and pH sensor and use those readings to control a chlorine and acid doser.
The sky really is the limit with what you can do with this board. See this write-up for more information. You can purchase the full board here.
