Create RF receiver and transmitter
$250-750 USD
Paid on delivery
I require the Complete PCB design and Firmware for the following:
RF Transmitter:
434,000 MHz
PCB to fit pre-designed enclosure
Battery Operated
3V CR2032 Preferred
Transmitter power >10dBm
Minimum Standby Current draw <10nA
PCB solder bridge to select Channel 1 or 2
Channel Selection done via a soldering bridge. Eg. Channel 1 J1, Channel 2 J2
Each Transmitter should be unique as to not interfere with other receivers in near proximity.
Specific button to be used. datasheet will be supplied
Enclosure DXF and Step file will be supplied to fit PCB into enclosure.
Cost effective PCB design is required.
RF Receiver:
434,000 MHz
2 Channel Wireless Receiver
9 – 32VDC Operating Voltage
Positive Output (Latched until Negative unlatch received)
Unlatch Negative input
Negative Output Channel 1 (Momentary) 2A
Negative Output Channel 2 (Momentary) 2A
Built in Buzzer (Buzzer signal when RF signal received, NO SIGNAL if LATCH ON)
Buzzer Specs: PCB Mount; 3500Hz; >90dB;
Learn Button ( PCB mount button )
Pair up to 50 individual transmitters
RGB Status LED
Should be resistant against irradiated and induced electro-magnetic noise
Learn Mode should reduced range to 50cm.
Transmitter Low Battery LED.
Low Battery LED should illuminated if last received transmitter battery is low.
All inputs and outputs should include short circuit protection, over current protection, reverse polarity protection.
Connector specifications will be supplied.
PCB Size limitations: Width 55mm, 45mm usable. Length <80mm
System should have a range of 50m
SMD components preferred for production.
Products should be economic to manufacture.
Products should comply to EN 300-220.
This project should include all PCB Gerber files, Altium files, Firmware for devices and source code as well as the code project for the Transmitter and Receiver.
