1.1. RN-111B Overview
The RN-111b “WiFly” radio module is a complete, stand alone, embedded wireless
LAN access device. The device has on board TCP/IP stack and applications. Requiring
only 4 pins (POWER, TX, RX, GND) to design in. Once initial configuration is set, the
radio can automatically access the WiFi network and send/receive serial data over UART.
• Fully Qualified 2.4GHz IEEE 802.11b Wireless LAN radio module.
• 32bit CPU, 230K ROM, 80KRAM, 4MB on board flash.
• On board ECOS -OS, TCP/IP stacks.
• 3.3V UART and SPI interfaces available to various applications.
• Accepts wide voltage range input 3.3V – 12VDC.
• Multiple Antennae options, SMA, U.FL, ceramic Chip, ¼ wave wire.
• Conforms to FCC, CE and the EMI standard of each country.
• Modular Approval: FCC ID: T9J-RN111b, ICS: 6514A-RN111b, CE: 0681
