The 40-pin EtherStem Module has a BrainStem 2.0 kernel (internal OS) allowing it to operate as a slave device and run reflexive actions simultaneously. A 40-pin BrainStem module can be networked with other BrainStem modules across the I2C bus at speeds up to 1Mbps.
A cross platform C++ API is available for high level software development using a TCP/IP socket interface.
Acroname is actively developing BrainStem 2.0 software and firmware for prime time. Please check the Acroname Dowload Center often for updates.
