Phase 1 — Evaluation Board Selection

Purpose

This document captures the candidate evaluation boards considered for Phase 1 hardware and the criteria against which they are compared. The goal is to pick a single board (or board + daughter-card combination) that realizes the architecture in Hardware Architecture with the lowest integration effort, while keeping a credible path to the Phase 3 custom PCB.

Four silicon vendors are in scope:

  • NXP

  • STMicroelectronics (ST)

Selection Criteria

The columns in the comparison table below are:

  • Manufacturer — silicon vendor.

  • Boards — the specific evaluation board, or controller + power-stage combination, under consideration.

  • Is Modular — whether the controller MCU and the power stage are on physically separate boards joined by a standard connector (allowing the power stage or MCU to be swapped independently), as opposed to a single integrated board.

  • Price — indicative public list price for the full combination, in EUR or USD as published by the vendor at the time of writing. Treat as preliminary; final pricing is captured in the procurement record.

  • Software Support — motor-control SDK, reference firmware, GUI tooling, and example projects shipped by the vendor.

  • CAN Support — whether a CAN transceiver is present on the board, or whether CAN must be added externally (relevant for the Phase 2 CAN milestone, MIL_043).

Detailed Analysis

NXP S32K144-Q100 + DEVKIT-MOTORGD: * Has both 3 phase currents and 3 phase voltage readings but they are combined with a header. Thus, to be able to read both current and voltage rework is needed.

  • Needs external power supply 10-18V.

  • Suggested motors are: Linix 45ZWN24-40 BLDC and Nanotec DB41M024030-A.

Both motor comes with hall sensor. Linix 45ZWN24-40 BLDC: 41Euro but none in the stocks hard to procure. Nanotec DB41M024030-A; Not much information. Motor can be selected seperately.

P-NUCLEO-IHM03: * Composed of X-NUCLEO-IHM16M1 (7-45Vdc, 1.5Arms), NUCLEO-G431RB, motor and power supply. * Motor: GBM2804H-100T pmsm * DC Power supply: 12V
