    Pimoroni have a wireless pack for Raspberry Pi Pico. This adds wifi capability with an ESP32 (and possibly bluetooth, more on that later). Wifi capability is great because it means I can teleoperate (remote drive) my robots, even if it’s just starting behaviors. In Learn Robotics Programming I have a chapter showing how to crate a nice web interface and remote camera/driving app to take advantage of Raspberry Pi 3a+ wifi. It’s something I’ve taken to adding to most of my robots. But what about Pico robots?
