PADI IoT Stamp is a highly integrated, single-chip, low-power WiFi controller with a built-in antenna. The stamp combines an ARM Cortex M3, integrated Flash, and RAM, WLAN MAC, WLAN baseband, RF balun, PA, LNA receiver, saw filter, and power management module. Designs for makers with high-speed SPI/I2C/UART interfaces for IoT applications with minimum Printed Circuit Board (PCB) area requirement. The PADI IoT Stamp is even smaller than a UK stamp size.
Designed with battery-powered Internet of Things (IoT) devices in mind, PADI IoT Stamp allows makers to build various low power consumption online cloud base IoT projects.
