M.2 Multifunction Analog I/O
M.2 Multifunction High-Speed Analog I/O Cards: Ever-expanding M.2 card lineup targets a wide array of applications
ACCES I/O Products announces the immediate release of a new family of M.2 multifunction analog I/O cards— the M.2-ADIO Family. This innovative line of 12 and 16-bit M.2 models starts with its flagship model, the M.2-ADIO16-8FDS. This high-speed, 16-bit multifunction analog input/output board is ideal for precision measurement, analysis, monitoring, and control in countless embedded applications. The M.2-ADIO16-8FDS can sample at speeds of up to 1 MHz for the board’s eight single-ended or four differential analog input channels. Standard features in the M.2-ADIO Family include four 16-bit analog outputs and 16 high-current digital I/O lines—all in the ultra-small M.2 2260/2280 embedded form factor (NVME compatible). Striking an excellent price/performance value, this family of boards also includes models with slower A/D speeds, no analog outputs, and a group of 12-bit modules for less demanding applications.
The M.2-ADIO Family comprises over a dozen models, with list prices ranging from $249 to $669, offering an unprecedented value. The cards feature seven software-selectable per-channel analog voltage input ranges, including 4-20 and 10-50mA current inputs (factory options). This channel-by-channel programmable gain feature enables the measurement of a wide range of large and small signals in a single scan, all under software control at up to 1 MHz. A 4 kSample FIFO and DMA-driven data are optimal when high data rates must be sustained for either short or long periods.
The four analog outputs each have five software-selectable ranges and can drive loads of up to 10 mA. The flagship FDS model features hardware-paced, eight-k-sample FIFO+DMA-driven Streaming Waveform Playback on one, two, three, or all four DACs, at any aggregate rate up to 1 Msps.
The 16 digital I/O lines can be used independently as simple input or output, external ADC trigger, ADC start conversion, DAC trigger (LDAC), watchdog status output, and more.
The cards are designed for use in harsh and rugged environments, including military and defense applications, as well as commercial and industrial settings such as medical devices, point-of-sale systems, kiosk design, retail, hospitality, automation, and gaming.
Key features of the M.2-AIO Family include:
- 2 Type B/M 2260/2280, with latching I/O connector
- 16-bit, bipolar, differential, A/D converter sampling at up to 1MHZ
- Software selectable as eight single-ended or four differential inputs
- Seven channel-by-channel Programmable differential input ranges from ±0.3125V up to ±12V
- A/D starts via software, external input, or periodic timer
- A/D “scan start” mode optimizes inter-channel timing, reducing skew
- High Impedance, 8-channel input: 500 MΩ
- 32K FIFO plus DMA for efficient, robust data streaming
- 16 digital I/O; 8 individually configurable for input or output
- Four 16-bit analog outputs with optional eight kSample FIFO+DMA Waveform Streaming
- 5 per-channel programmable ranges: 0-5V, 0-10V, ±2.5V, ±5V, ±10V
- Outputs drive ±10mA
- Onboard watchdog with status output
- RoHS compliant standard
All ACCES M.2 cards feature high-retention latching connectors for shock and vibration mitigation, as well as an optional extended operating temperature range of -40°C to +85°C. The small size (M.2 2260/2280: 22mm x 60mm/80mm) allows for maximum performance in applications where space is a valuable resource. The newer M.2 form factor offers a compact footprint for embedded applications where space is critical. This M.2 card is compatible with standard NVMe sockets, which are common on all modern motherboards.
Factory options include extended temperature, current inputs (4-20mA, 10- 50mA), and voltage dividers for higher voltage inputs. Additional customization options include conformal coating, custom software / product-labeling, and more — even entirely new features, enabled by our advanced FPGA-based design!
These cards are compatible with most operating systems and include a free software package for Linux and Windows. This package contains sample programs and source code in C# and Delphi for Windows. Linux support includes installation files and samples for the programming level, provided through our open-source kernel driver. Third-party support includes a Windows standard DLL API library usable from most popular application programs. Embedded OS support encompasses the family of Windows Operating Systems, including IoT. ACCES also now offers a VxWorks driver/library for the ultimate real-time process monitoring and control solution.
