This is the newest 2.4GHz transceiver from Nordic Semiconductor, using the nRF24L01+ module. Dimensions: 0.8x0.9". This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice!

Each button has a hole underneath that accepts either a 3mm or 5mm standard LED. The idea is that you can create a button interface of your choice with the ability to display simple colors under each button. Mainly, we wanted to use our tri-color LEDs to create a full RGB color for each button.

Black 1/8" ABS plastic. We use four 4/40-0.5" size screws matched with plastic standoffs to attach the 2x2 button pad and Simon project boards. Using two of these bezels with two of the bottom bezels will create a 4x4 bezel appropriate for the full button pad.
