Universal motherboard designed for sensor based, monitoring and home automation projects based on ESP32- WROOM microcontroller. The uniqueness of CG_mini lies in the distribution of all ports and interfaces to JST 2.54 connectors, which allows you to create complete solutions without using a development board, soldering and developing your own PCB.
Any interfaces In total, the board has three I2C interfaces, 2 UARTs, 1 analog port, 1 OneWire interface, 1 SPI interface and one logic port, to which a load of up to 0.5A can be connected (1 relay / beeper). Moreover, each connector has the necessary power.
JST 2.54 connector
JST 2.54 connector provide simple and reliable connection of external sensors and executable devices.
For the implementation of universal circuits of visual signalization and monitoring, board has 2 RGB led diodes.
External watchdog timer
To ensure a high degree of reliability, there is a hardware watchdog timer that implements a hardware reset of the microcontroller every 60 seconds (or more often), which allows the device to return to work in the event of freezing.
5 and 9-28V supply
The board has a DC-DC power converter which allows powering the board with a voltage of 9 - 28V. For this, the DC barrel connector and terminal connector are wired on the board. It also provides the ability to power from USB Type-C (5V).
