Pros

• By far more energy efficient than a Raspberry Pi as observed
• The smallest microcontroller board you have seen with both Wifi and Ethernet, yet.
• great on-board browser IDE with full debugger. No need for installing software which will be great for the user.
• You will be able to use external antenna, but this will not be software switchable.

Cons

• Unfamiliarity with the device
• Complicated uses and design

Overall, this product need more advertisements and exposure for the users to really familiar with it since it can be very beneficial
