This development board runs the TI CC3220 is for IoT applications featuring an ARM Cortex-M4 with an associated network processor that runs the whole Wi-Fi, TCP/IP and TLS stack so the main chipset doesn't have to do any of the networking or security freeing up the whole ARM Cortex-M4 for the IoT application use. At Linaro Connect San Francisco 2017 they are showing it running TI RTOS and Zephyr. This board also features the LiPo battery connector. Adding also IPv6 support and TLS suite, an ARM Cortex-M4 with 1MB Flash, 256KB RAM running at 80Mhz. It's very low power it can run for years off 2 AAA battery cells with the right duty cycle.
