Missed the GM4s? Us too. It took much longer than we expected to get them through clearances this time, but they've finally made it to our doorsteps!
Synapse 220 Modules
|RF220SU SNAP Engine, 2 Mbps 2.4 GHz
WiFi is good, but the SNAP Engine Model RF220SU is an IEEE 802.15.4, low-power, very robust solution for embedded wireless control and monitoring networks. With auto-mesh networking (try that WiFi...). 2Mbps on the 2.4GHz spectrum and RP-SMA or U.FL selectable antenna.
Similar to the RF220SU, this one offers a switchable internal/external U.FL antenna, communicating at speeds up to 2Mbps, with a maximum 4.8km (3mi) range.
The ESP8266 is a low-cost WiFi chip with full TCP/IP stack and microcontroller capability. This small module connects to a WiFi network and makes TCP/IP connections. It was introduced in 2014 and has exploded in popularity since.
|AI-Thinker ESP8266 ESP-01 Wifi microcontroller
The original low-cost, low-pin count IoT controller, ideal for connecting a few IO channels to the Internet.
|ESP-12F AP+STA Remote Serial Port WIFI Controller / Module
You can't turn over an internet-connected rock without finding an ESP8266 of some sort wired to it. This ESP-12F AP+STA is a solid way to connect to the "Internet of Things" with even more IO channels than the ESP-01.
Designed by SeeedStudios, the Wio Link is designed to simplify your ESP8266 IoT development. It links with their Grove ecosystem for rapid prototyping and allows quick creation of IoT applications by virtualizing plug-n-play modules to RESTful APIs with mobile APPs. That means they've made it very easy to use.
Another Seeed innovation, this is like a junior version of the Wio Link, offering full Grove Support, LiPo Support, and a mature API. This little guy is cheaper, smaller and lighter.
