It ships with four pre-installed modules: the MPIO-96 SPI module (96 reconfigurable mixed-signal channels), the 6\u00d7 IDC N-TOP breakout (fixture wiring), the M.2 PSU module (dual-channel programmable supply), and the Communication module (I\u00b2C, UART, SPI, JTAG, fan control, and RGB status indication). Lifetime Accordion Pilot and Accordion Shell licenses are included.<\/p>\n<p>On the signal side, the A2 Plus presents 96 user channels via six standard 20-pin IDC connectors. Each channel can be reconfigured at runtime \u2014 analog input, analog output, or pseudo-digital with programmable VL\/VH thresholds. Open-drain and floating-output behaviour are emulated by setting thresholds out of range, useful for external pull-ups and mixed-signal nodes. Resolution is bounded by the AD5592R devices on the MPIO-96: 12-bit ADC and DAC, 0\u20135 V typical in 2\u00d7 mode.<\/p>\n<p>On the power side, two fully independent DC outputs are configured and read entirely in software via PMBus. Each channel covers 0\u201320 V and 0\u201310 A; the module enforces a 60 W combined ceiling and supports overvoltage, undervoltage, overcurrent, temperature, and startup-timing protection. Telemetry \u2014 output voltage, current, power, input voltage, input current, and temperature \u2014 is available per channel as discrete read-only registers. Outputs are disabled at boot and require explicit software enable.<\/p>\n<p>On the communication side, the A2 Plus exposes two software-controlled I\u00b2C buses (each with programmable rail and switchable pull-ups), an RS232 UART, SPI, and JTAG. SPI and JTAG share a single programmable rail and so cannot be powered at different voltages simultaneously \u2014 sequence them in software if both are needed. Two PWM fan headers with tachometer feedback and eight RGB status LEDs (mapped to bus, power, fan, and ADC\/IO indicators) round out the operator-visible side.<\/p>\n<p>The A2 Plus is a fully fledged Accordion node. It is reachable on the network by hostname or IP, addressed by Accordion\u2019s standard channel-naming convention, and controllable through the Accordion API \u2014 Python, C#, TestStand, LabVIEW, or REST. The Pilot and Shell licenses ship with the unit; the API clients are open and require no additional licensing.<\/p>\n<p>The chassis still has free capacity for later expansion: three SO-DIMM slots, three N-TOP slots, and one M.2 slot are unpopulated. The Communication module sits on a dedicated communication position and does not consume an N-TOP slot.<\/p>\n<p>Further information: <a
