Description:
RF-2.4G Modular PCB Assembly is an i/o board used in the family of REMOTE POWER
SWITCH PRODUCTS,The board has RF+MCU POWER circuit OSC circuit RESET circuit
and wireless module.
CIRCUIT DESCRIPTION:
Referring to the block diagram there are four main sections of circuit:
1, el2401 IC MCU CIRCUIT
2, CLOCK CIRCUIT
3, ANTENNA CIRCUIT
4, RESET CIRCUIT
Communication with the RF-2.4G Modular is accomplished through two side PCB
PADS, the 2.4G ISM RF circuitry is contained on the module.There is no extraexternal
antenna on the module, so the radio output from the moduleconnects to an F-type PCB
antenna on the PCBA. The RF-2.4G Modular operates from 3.3v supply source on the
main PCB
The RF-2.4G Modular installation and use:
The module is soldered to the PCBA.PADS on the PCBA make contact to the 3.3V
supply, all controller is accomplished through the modules two side pads.
