PADI IOT STAMP
PADI IoT Stamp is a highly integrated, single-chip, low power WiFi controller with 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 US stamp size.
