STEMinds is gearing up to launch a smart agriculture IoT kit that can be managed through a phone app over MQTT, featuring a custom-made Eduponics Mini Board apart from the onboard sensors and modules.

The Eduponics Mini development board is based on the ESP32-WROVER microcontroller with an integrated SPI flash of 4MB and PSRAM of 8MB. The board also packs an AT24C02 EEPROM chip that supports up to eight devices on the bus and is widely used in low-power commercial applications.

It comes with water quantity, soil moisture, and pump XH2.54 interfaces along with a tiny relay that can be used for controlling the pump.

The Eduponics Mini Board is powered by a 12V DC power interface and has a USB-C connector as well. The microcontroller is pre-installed and tested with MicroPython, which is based on Python3. To program the device, you can use both MicroPython using Thonny IDE or C++ via Arduino IDE.

STEMinds also offers an extension board that enables the connection of four additional soil moisture sensors (or any other analog input devices) and extra output devices for monitoring up to four other plants. The board is designed using an ADS1115 for ADC support and an MCP23017 for GPIO control.

All code libraries and drivers are open source on GitHub. To get started with the development kit, STEMinds has provided a detailed guide on the Wiki page. For more details, you can sign up on Crowd Supply to get notified when the campaign goes live.
