View detailsWhich ESP32 should you choose?
For compact Wi-Fi and BLE sensor nodes, the ESP32-C3 Super Mini is a strong low-cost option. The ESP32-WROOM-32 is the broad general-purpose choice, while ESP32-S3 boards provide newer peripherals and, on the N16R8 model, substantially more flash and PSRAM. Boards with OLED or LoRa hardware are useful when you want those functions already integrated.
