1.0 N240D RF Module
1.1 Description
The N240D is a low power wireless response keypad module. It has 14 available inputs, and two available outputs.
The N240D module is used to interact with an audience so they can provide real time feed back to questions. It
communicates at 2.4GHz, GFSK to a base station. The base unit polls keypads, and displays result.
The overall operation of the N240D module is controlled by a microcontroller. This microcontroller is powered
from approximately 3V and uses a 16 MHz reference. The microcontroller handles control of the RF
communications and keypad inputs.
RF communications use the Nordic 2401A 2.4 GHz transceiver. The Nordic chip uses a 16 MHz reference
oscillator that is shared with the microcontroller for TX/RX and is also powered by 3V. The Nordic transceiver uses
an integral PCB inverted F antenna with a gain of approximately 3.6 dBi.

1.2 Keypad Battery Replacement
Each keypad is powered from a single CR2032 Lithium Coin cell battery. The battery is replaceable. To replace
battery, slide out the old battery from its holder, and replace with a new battery noting its polarity. The negative
side of the battery should be facing the PCB.
