Product Features
product description
The board features a developer-friendly expansion port that supports I2C, SPI, UART, and ADC pins. All 14 expansion pins can be used as GPIOs. Note: Sanguinololus design is excellent, but if you want to run a hot bed not enough to carry the traces of heat required by the current functional Sanguinololu board on the bed.

note:

Contains 4 A4988 boards, we also have this board,
