The Wio Terminal is a great product for makers who need to create projects with both Bluetooth and Wi-Fi connectivity. It's powered by Realtek RTL8720DN, compatible with Arduino or MicroPython, with onboard 2" LCD screen plus an IMU (lris3dhtr), microphone buzzer & more.
This mini module has a lot of great features in one compact enclosure making product ready design easy as pie, I love the fact that it's Azure certified so can be easily connected to the Azure IoT hub or other services.
One thing it does miss is an inbuilt battery, but there is a battery module available which I've linked to at the bottom of this article.
A couple of things I found odd about the inbuilt components.
The light sensor and infrared emitter are on the back of the board, so they are no real use for sensing the light level or sending IR to, for example, a TV or Air-Con unit.
I would have thought that having these on the front or even side of the module would have been a better option, but it's a small gripe.
* If you're looking at adding some extra features on top like sending data over USB connection then think no further than our raspberry Pi 40 pin GPIO which also includes Grove ports to boot.
