I/O Extension for DFRobot FireBeetle

The extension for the FireBeetle, which allows you to connect a larger number of digital pins with 10  pins of i/O and 5 analog pins. It communicates via the SPI, UART and I2C bus. Extension is an adapter for sensors and modules from the Gravity series, it can be used to communicate between the sensors of Gravity and FireBeetle. Each sensor has an independent power pin. The kit includes 2 x 18 pin of 2.54 mm and 2 x slot of 18 pin of 2.54 mm.
