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.
