The second bus is the Connector Euler, It provides additional features to this device, in particular a port to a sensor of temperature; ports I2C, I2S, SPI, SPDIF, GO, and UART; two tickets, and an output of power; and the port of loading for the battery external that we can add optional.
Pili ya mabasi hayo ni ya Kiunganishi Euler, Inatoa vipengele vya ziada katika kifaa hiki, hasa kwa bandari ya Kihisi joto; bandari I2C, I2S, SPI, SPDIF, KWENDA, na UART PATANIFU; tiketi mbili, na matokeo ya nguvu; na bandari ya kupakia betri nje kwamba tunaweza hiari.
