Silent stepper driver

Edit

A 3D-printer or camera slide axis that should not whine. UART or STEP/DIR, stealthChop or equivalent, and a sense-resistor story.

Starting part numbers

  • A4988SETTR-T

    Allegro

    STEP/DIR fallback when silent is optional.

Live parts

On-demand from Nexar and/or DigiKey. Nothing here is a catalog Byuse owns. Specs appear only if the API returned them.

No distributor key is set. Browsing still works. To see live parts, add one of these pairs to .env.local and restart the dev server:

  • NEXAR_CLIENT_ID
  • NEXAR_CLIENT_SECRET
  • DIGIKEY_CLIENT_ID
  • DIGIKEY_CLIENT_SECRET

Nexar needs NEXAR_CLIENT_ID and NEXAR_CLIENT_SECRET. DigiKey needs DIGIKEY_CLIENT_ID and DIGIKEY_CLIENT_SECRET.
