Overview
• Baud rate speeds: 1200bps up to 921Kbps, non-standard baud rates can be programmed.
• RN-41: Class 1 radio, 330’ (100m) distance, 12dBm output transmitter, -80dBm typical receive sensitivity
• RN-42: Class 2 radio, 60’ (20m) distance, 4dBm output transmitter, -80dBm typical receive sensitivity
• Frequency 2402 ~ 2480MHz,
• FHSS/GFSK modulation, 79 channels at 1MHz intervals
• Secure communications, 128 bit encryption
• Error correction for guaranteed packet delivery
• UART local and over-the-air RF configuration
• Auto-discovery/pairing requires no software configuration (instant cable replacement).
• Auto-connect master, IO pin (DTR) and character based trigger modes
