AxH is an Italian Community of homebrewing passionates. AxHTherm is a smart device born to help home brewers to take control of their fermentation chambers. It allows to define temperature steps, temperature ramps, and gravity set points to guide your fermentations! You don't have to be nearby your fermentation chamber anymore! With AxHTherm you can remotely manage your fermentations, and track their progress with the aid of BrewFather and/or ThingSpeak integration! Remote control is possible straight from your smart device and/or your PC. AxHTherm 2V5 is an enhanchement of AxHTherm project. This project was born to give a PCB to facilitate the assembling of a Temperature Controller (AxH Therm) but at the end it becames a general purpose PCB. It include - 8 Outputs ( controlled by ULN2803). 3 outputs are driven directly by wemos with 3 status indicators (led) and the others via I2C - 3 additional I/O controlled by I2C - I2C bus (for OLED and more) - Serial Bus - Tiny RTC - ... and more This PCB is part of AxH project and its scope is to provide an easy component to facilitate AxHTherm's assembling process.
