Default shipping 315MHz , if you need 433.92MHz , please leave message with the order , thanks!

This module is work with below items:

1, ASK Transmitter: 3x TX-5 10dBm 1.8 - 5V 315M 433M ASK Transmistter RF Wireless Arduino RC Switch

2, ASK Receivr : 3x RXB61 3.6 5.5V 315 433M ASK OOK Receiver RF Wireless Arduino RC Switch

To uploading sketch through Arduino IDE , you need an USB to UART cable , below item for choice:

1, UC-340G: UC-340G USB to UART TTL RS-232 USB2Serial Light Replace FT232 CP2102 Android

2, UC-2102: USB 2.0 SERIAL for Arduino UC-2102 USB to UART Cable 2.45mm to 2.0mm

Feature

1. Massduino MD-328D with 32KB Flash , 2KB SRAM
2. Fully Arduino IDE development
3. Onboard ASK transmitter and receiver
4. Connection to exist ASK device which with same frequency. (such as remote controller / PIR sensor / Magnetic / etc.)
5. Two ISM band for choice:
6. RF-1531-315: 315MHz
7. RF-1531-433: 433.92MHz
8. Arduino lib support : https://github.com/sui77/rc-switch
9. 1x digital IO for transmitter
10. 2x digital IOs for receiver
11. All other IO are sink to connector for user usage
12. Wide operation voltage : 2.4 to 4.5V, this feature let user can be use Li-ion battery powered without LDO. recommend voltage is 2.4 to 3.6V.
13. 200m outdoor working distance and good for home using
14. Ultra-low power consumption - down to 17uA in Standby mode
15. Use Superheterodyne IC ,better than super-regenerative receiver
16. RX circuit with shutdown function

Specfication

1. Operation voltage : DC 2.4 to 4.5V
2. TX Output power level: 10dBm
3. TX Supply current (Pout = 10dBm): 16.8mA
4. TX Standby delay time: max 120mS
5. TX Data rate: 10Kbps
6. RX Max input power: 10dBm
7. RX Sensitivity: -109dBm
8. Receive Modulation Duty Cycle: 20% to 80%
9. RX current: 315MHz: 7.8mA
10. RX current: 433MHz: 9.8mA
11. Shutdown current: 18uA
12. Polled operation current (100:1 duty-cycle): 78uA

Notice:

    The TX and RX can not working in the same time.

    In TX Mode: D7 = High, Set RX shutdown

    In RX Mode: D7 = LOW , D4 = Low , Set TX shutdown

Demo Code

 

 C++ Code 

int TX_Data = 4; int RX_Data = 2; int RX_ShutDown = 7 ; #define RF_Mode_RX      0 #define RF_Mode_TX      1 #define RF_Mode_IDLE    2 void setup() {   Serial.begin(115200);   mySwitch.enableTransmit(TX_Data);      pinMode ( RX_ShutDown , OUTPUT );   RF_1531_Set_RF_Mode ( RF_Mode_TX ) ; } void RF_1531_Set_RF_Mode ( int RF_Mode ) {   switch ( RF_Mode ) {        case RF_Mode_RX:       digitalWrite ( TX_Data , LOW );       digitalWrite ( RX_ShutDown , LOW );       break;     case RF_Mode_TX:       digitalWrite ( RX_ShutDown , HIGH );       break;     case RF_Mode_IDLE:       digitalWrite ( TX_Data , LOW );       digitalWrite ( RX_ShutDown , HIGH );       break;     default:       break;   } }
