TechnologyThe Microchip Technology ATWINC1500 802.11 b/g/n Module, PCB Ant., FW 19.7.6 (ATWINC1500-MR210PB1976) is an integrated radio module that enables embedded systems to add Wi-Fi connectivity easily. The module utilizes a single-stream, 2.4 GHz 802.11 b/g/n radio connected to an integrated ARM Cortex-M0 microcontroller to process 802.11 frames, provide network and IPv4/IPv6 stack support, as well as an integrated AT86RF233 Low-Power 2.4 GHz RF Transceiver to perform the actual radio operations. It also offers integrated hardware support for advanced Wi-Fi security modes such as WPA, WPA2, and WEP. The power profile provides support for a low Sleep Current of 1µA and a Maximum Tx Current of 138mA. The ATWINC1500-MR210PB1976 comes with a built-in PCB Antenna, PCB Size of 18mm x 22mm (20mm x 14mm excluding antenna), and WiFi Firmware 19.7.6.
