Great NFC powered board!

The NFC functionality works great and has been very reliable. This board is a great addition to any project involving NFC.

Pros
  • Easy setup and reliable NFC functionality.
Cons
  • Limited applications beyond NFC.

Great screen with minor issues

The screen is excellent; I taped it to the inside of the front door with double sided tape so I could keep notes or jokes for my kids. The case is a little thin; It feels like it'll part with just a slight bend and it can be difficult to find the NFC dot, but those are minor issues.

Pros
  • NFC enabled wireless display update. Passive NFC solution, no battery required, no tangle of wires, stable performance.
Cons
  • A small change

Superb E Ink display

This is a great E Ink display that I use for announcements in my class. It features a microUSB connector that can be used for power delivery if your current Android device isn't powerful enough to refresh the screen. It is very reliable and appears to be very durable. This is the first size I've seen.

Pros
  • Power supply: Wireless. Grayscale: 2. Display color: black/white. Refresh time: 5s (not including data transfer time). Point pitch: 0.205 × 0.204. Display size: 163.2mm × 97.92mm. Resolution: 800×480. Overall Dimensions: 195.84mm × 137.68mm. Viewing angle: >170°
Cons
  • Newer model could have been chosen
