Wi-Fi, Bluetooth Classic and BLE on a board that costs less than most shields. Two cores at 240 MHz means you can keep a network stack running without it stealing time from your control loop. The Lab emulates this one including the network stack, so MQTT and HTTP examples run in the browser before you own the hardware.
