Wi-Fi for an IoT node

Edit

Join a home AP, speak MQTT or HTTP, and still have GPIOs left. Modules are often the right answer; these are the chips underneath.

Starting part numbers

From the local map. These are examples, not the live result list.

  • ESP32-C6-WROOM-1-N8

    Espressif

    Wi-Fi 6 + BLE, when you want a newer radio.

  • ESP32-S3-WROOM-1-N16R8

    Espressif

    Module; USB-Serial/JTAG, plenty of flash/PSRAM.

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.
