title: Adafruit (PID 3213 Assembled Feather Huzzah w/ ESP8266 WiFi with Stacking Headers
text: Product Description Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit Feather HUZZAH ESP8266 - our take on an 'all-in-one' ESP8266 WiFi development board with built in USB and battery charging. Its an ESP8266 WiFi module with all the extras you need, ready to rock! We have other boards in the Feather family, check'em out here. At the Feather HUZZAH's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. We wired up a USB-Serial chip that an upload code at a blistering 921600 baud for fast development time. It also has auto-reset so no noodling with pins and reset button pressings. To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. Here's some handy specs! Auto-reset support for getting into bootload mode before firmware upload 9 x GPIO pins - can also be used as I2C and SPI 1 x analog inputs 1.0V max Built in 100mA LiPoly charger with charging status indicator LED, can also cut a trace to disable the charger Pin #0 red LED for general purpose blinking. Pin #2 blue LED for bootloading debug & general purpose blinking Power/enable pin Comes fully assembled and tested, with a USB interface that lets you quickly use it with the Arduino IDE or NodeMCU Lua. (It comes preprogrammed with the Lua interpreter). Product Description Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly!

title: Adafruit 4201 Airlift – ESP32 WiFi Co-Processor Breakout Board
text: Product Description Give your plain ol' microcontroller project a lift with the Adafruit AirLift - a breakout board that lets you use the powerful ESP32 as a WiFi co-processor. You probably have your favorite microcontroller (like the ATmega328 or ATSAMD51), awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if its using the latest TLS/SSL encryption (it has root certificates pre-burned in). Having WiFi managed by a separate chip means your code is simpler, you don't have to cache socket data, or compile in & debug an SSL library. Send basic but powerful socket-based commands over 8MHz SPI for high speed data transfer. You can use 3V or 5V Arduino, any chip from the ATmega328 or up, although the '328 will not be able to do very complex tasks or buffer a lot of data. It also works great with CircuitPython, a SAMD51/Cortex M4 minimum required since we need a bunch of RAM. All you need is an SPI bus and 2 control pins plus a power supply that can provide up to 250mA during WiFi usage. We placed an ESP32 module on a PCB with level shifting circuitry, a 3.3V regulator, and a tri-state chip for MOSI so you can share the SPI bus with other devices. Comes fully assembled and tested, pre-programmed with ESP32 SPI WiFi co-processor firmware that you can use in CircuitPython to use this into a WiFi co-processsor over SPI + 2 pins. We also toss in some header so you can solder it in and plug into a solderless breadboard. The firmware on board is a slight variant of the Arduino WiFiNINA core, which works great! At this time connection to Enterprise WiFi is not yet supported.

text: Product Description At the feather huzzah's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This controller contains a tensile chip core as well as a full WiFi stack. You can program the controller using the arduino ide for an easy-to-run Internet of things core. We wired up a high-quality silabs Cp2104 usb-serial chip that an upload Code at a blistering 921, 600 Baud for fast development time. It also has auto-reset so no fiddling with pins and reset buttons. The Cp2104 has better driver support than the CH340 and can do very high speeds without stability issues. To make it easy to use for portable projects, we added a connector for any of our 3.7V lithium polymer batteries and built in battery charging. You don't need a battery, for it will run just fine straight from the Micro USB connector. But If you do have a battery, you can take it on the go, and plug in the USB to recharge. The feather will automatically switch over to USB power when it's available. Product Description At the feather huzzah's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic.

Great for pairing with a microcontroller with USB support, or adding USB 5V power to a project. We use a micro-B connector with through-hole shielding pads for an excellent strong connection - it won't rip off by accident! Comes with one fully assembled and tested micro B breakout PCB and a small stick of 0.1" header so you can solder it on and plug into a breadboard.
