The National Instruments myRIO-1900 is an embedded portable Reconfigurable I/O (RIO) system. The NI myRIO-1900 provides analog input (AI), analog output (AO), digital input and output (DIO), audio, and power output in a compact embedded device. The NI myRIO-1900 connects to a host computer over USB and wireless 802.11b,g,n.

The myRio uses a Xilinx Z-7010 processor with 2 cores at 667MHz each. A NVM (non-volatile memory) of 256MB and a DDR3 memory of 512MB with a clock frequency of 533MHz and a 16bit data bus. The USB host and device ports are 2.0 Hi-Speed ports. The Audio Input is a one stereo input consisting of two AC-coupled single-ended channels. Input impedance is 10kΩ at DC with a nominal range of ±2.5 and a bandwidth at 2Hz to 20KHz as expected for audio.

The NI myRIO-1900 has analog input channels on myRIO Expansion Port (MXP) connectors A and B, Mini System Port (MSP) connector C. MXP connectrores carry  identical sets of signals.
