Node MCU ESP8266 with IR Rx/Tx diode and 433MHz Rx/Tx store and send codes.
/nodeIRDuplicator : Done! IR send and receive through webserver (connect to wifi or set as AP). First code test. All accepted codes are transformed into buttons for the possibility to duplicate individual codes and a field to insert and send your own code. Also you can save codes to txt file.

- OK install NodeMCU drivers and connect to IDE
- OK Testing IR Rx
- OK Testing IR Tx on Node MCU with IRremoteESP8266 lib
- OK Webserver
- OK AP/HOST mode
- OK Save IR codes as buttons
- OK Send custom IR code
- OK Save IR codes as txt file
- Open saved codes
- Send saved codes
- Repeat for RF 433MHz (simple rx/tx, but more modulations,freq. etc.)
- Make beauty and user-friendly GUI for web (responsive for mobile devices of course)
NodeMCU with ESP8266
IR emitting diode (950nm tested) ==> D0 (GPIO-16)
IR sensor (KY-022/VS1838B) ==> D1 (GPIO-5)
433MHz receiver XD-MK-5V (STX882 better)
433MHz transmitter XD-FST (SRX882 better)
I'm trying the HC-12 SI4463 module but no luck yet
Flipper Zero uses the CC1101 chip which supports more modulations and is overall more suitable for our purposes (once I buy the module I will try it)
- Li-Ion 18650 cell
- BMS for 18650
- USB connector for charging
- antennas, case
my home RF remote freq.: 433.92MHz ASK modulation for testing
