STEMinds Eduponics Mini Extension Board

STEMinds Eduponics Mini Extension Board V1.0 is designed to extend the already existing capabilities of the Eduponics Mini Development Board. This Extension Board includes an extra 4 analog inputs, 4 relay output to control lights, pumps, and receive data from sensors such as pH and EC. The Eduponics Mini Extension Board integrates super low power capabilities with internal MOSFETs that can be turned on/off accordingly. This Extension Board is based on the I²C protocol and requires only 2 wires to operate. The Eduponics Mini Extension Board is compatible with Arduino, Raspberry Pi, and other boards. This Extension Board features ADS1115 4 channel accurate ADC chip and MCP23017 I²C 8 channel IO extension. The STEMinds Eduponics Mini Extension Board V1.0 is available in 53mm x 71mm dimensions.
