Specifics
415MHz to 455MHz(GFSK) Operation
1000 m unobstructed range - depend on transmitter power supply
19200bps transfer rate
Low cost, small and light weight
Use the modules directly via USB to PC or connect them to your microcontroller. It include a pair of transceivers.
By using electronic bricks, you may connect Arduino compatible boards easily with various digital, analog and I2C/Uart interfaces. These the breadboard-less firm connection are prepared to extensive modules like poteniometers, sensors, relays, servos...even buttons, just plug and play.
Note: the baud rate will automatically go down to 1200 bps if the distance is far. Make sure that the data transmitted does not exceed 150 bytes per second. Adding a 50ms delay will also help with data transmission / reception.
Package includes:
2 x APC220 Module
1 x USB-TTL converter
2 x Antenna
Sample Code:int ledPin = 13; int val; void setup() { pinMode(ledPin, OUTPUT); Serial.begin(19200); } void loop(){ val = Serial.read(); if (-1 != val) { if ('A' == val) { digitalWrite(ledPin, HIGH); delay(500); digitalWrite(ledPin, LOW); delay(500); } } }
