Features

Examples of available modules are:

  • Programmable power:2 PSU module (ESH10000533) — dual channel, 0–20 V, 0–10 A, 60 W combined, PMBus telemetry. Mini-PSU (ESH10000662) for lower-power rails.
  • High-density mixed-signal I/O: MPIO-96 SPI module (ESH10000568) — 96 channels of 12-bit analog and pseudo-digital I/O. 6× IDC breakout (ESH10000355) for fixture wiring.
  • Precision instrumentation: Precision ADC/DAC module (ESH10000590) when 12-bit MPIO is not enough.
  • Communication and control: Communication module (ESH10000359) — 2× I²C, UART (RS232), SPI, JTAG with programmable rails, fan headers, and RGB status LEDs.
  • Battery simulation: Battery Simulator (ESH10000556) for charge/discharge profiles and protection-circuit testing.
  • Specialty: PoE M.2 module (ESH10000534), Tone audio module (ESH10000560).

Datasheet

further information

The Accordion A2 Build is a configuration of the Accordion test platform — the same chassis, control system, and software stack as the Lite and Plus bundles, assembled to a specification matched to a single test bench. Where the Lite and Plus ship with fixed module sets, the Build is assembled from the standard Accordion module library to fit a specific application: power profile, channel count, communication interfaces, instrumentation, and form-factor constraints.

The A2 chassis is software-defined. Every channel is addressable by name; every protocol bus and every supply rail is configured at runtime. Modules are slot-mapped into the chassis (top-side SO-DIMM and N-TOP, front-panel M.2, dedicated communication TOP), and a custom configuration stays consistent with the Accordion naming convention so existing Pilot workspaces, TestStand sequences, and Python or C# scripts continue to work as the bench evolves.

A custom build is appropriate when the bundled configurations do not fit — for example, when the test program needs more programmable rails than the Plus carries, an instrument the standard bundles do not include (precision ADC/DAC, battery simulation, audio), or a specific mix of channel types the Lite cannot provide. The chassis is the same in every case; only the populated modules differ.

A custom A2 is a fully fledged Accordion node — reachable on the network by hostname or IP, addressable through Accordion’s standard channel-naming convention, and controllable through the Accordion API — Python, C#, TestStand, LabVIEW, or REST. Lifetime licenses for Accordion Pilot and Accordion Shell are typically included; bundled software depends on the configuration agreed during specification.
