Technical detail

Wireless linkIt communicates on 2.4 GHz IEEE 802.11b/g. Over TCP/IP and WPA2 it holds a sustained 4 Mbps data rate and supports Adhoc connections.

Serial interfaceUART and SPI data and control interfaces come with 10 general purpose digital I/O ports and 8 analog sensor interfaces.

Memory and softwareIt carries 8 Mbit flash memory and 128 KB RAM. The ECOS-OS and TCP/IP stacks ship onboard, and a real-time clock handles wakeup and time stamping.

PowerIt runs on a 3.3 V regulated supply or a 2-3 V battery. Draw stays at 10 uA in sleep, 50 mA on receive and 100 mA on transmit.

CertificationsIt is certified for WPA2-PSK Wi-Fi communication. The module is FCC, CE and ICS certified and RoHS compliant.
