The LinkIt™ Connect  7681 module  is a low-cost, low-power consumption component for IoT devices. The module integrates the MediaTek MT7681, which supports single stream IEEE 802.11b/g/n, provides GPIO and PWM for intelligent control and a UART interface for device communication.
The module includes an integrated Wi-Fi antenna and IPEX socket for an external antenna. 8Mbits flash helps reduce your platform size, along with a power management unit for a single 3.3V power source for cost effective design.
The 32-bit RISC MCU offers 802.11b/g/n drivers, supplicant and TCP/IP protocol stack for networking applications, and can operate in station or softAP mode. The module is therefore an ideal solution for embedded devices needing to enable networking services with minimal design effort.
The LinkIt™ Connect 7681 module is part of the LinkIt™ Connect 7681 development platform from MediaTek Labs. This development platform delivers you the tools and documentation to prototype your IoT device and create its final design, which you will complete with this module before delivery to your customers. This module is included in the LinkIt™ Connect 7681 development board.

Does the "Ink"Color Bag have silver tone hardware? (Chain)? It is hard to tell in photo

I bought the black one and the chain is gold color. Not sure of the ink bag.

You need a WiFi Internet connection, and a smartphone or tablet for the Echo App. That's it. It is easy to set up, but it may take you a while to figure out all of the little things that the Echo App can do.

BEWARE this is NOT STEREO and it is NOT MONO. This is only one channel. You will not hear part's of songs (recorded in stereo) that are only played through the left channel. Kinda ridiculous. Still it is a decent sounding speaker.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
