Adafruit 2821 Feather HUZZAH With ESP8266 WiFi
Adafruit Feather Main Boards - Adafruit 2821, The Adafruit Feather HUZZAH with ESP8266 WiFi uses the Internet of Things chip of choice, the ESP8266, running at 80MHz and with Arduino IDE compatibility. Adafruit have teamed up this popular chip with a CP2104 USB-serial chip allowing you to upload code at an amazing 921600 baud, plus it also handles the auto-reset to keep the bootloader happy. The ESP8266 has 4Mbytes of Flash memory, 9 x GPIO pins, 1 x analogue input (1.0V max). New to Feather? Adafruit have designed a range of processor boards with a consistent board shape and pinout together with a range of add-on boards with a huge range of functionality. The main boards are based on several popular 3.3V DC microcontrollers (MCU) so that you can choose the one that suits your
requirements or your budget. MCUs include the 32U4, Atmel ATSAMD21G18 with an ARM Cortex A0 core, and the popular ESP8266 which is widely used in Internet of Things (IoT) projects. Because Adafruit has used the smallest components available there's room at one end of the board for a specialist function such as an SD-card holder, Bluetooth LE, packet radio, LoRa, a prototyping area or even WiFi. The Feather main boards feature a USB port for power and programming, a LiPo battery connector, and support for serial, I2C and SPI in hardware. Each one has a 3.3V DC regulator which is able to supply up to 500mA peak current. The boards have a 100mA LiPo charging function with a status indicator LED and there's also a general purpose LED for blinking. The Feather boards are about &8531; x
the size of an Arduino UNO and there's even a Reset button. Once you've chosen your processor, select one or more FeatherWing add-on boards and get developing. The range includes development tools such as prototype boards and an over-size board with screw terminal blocks for external wiring. Supplied with an assembled and tested main board plus strips of 01.in. header pins for you to solder on as required. Adafruit supply an extensive free tutorial which contains everything you could need. Please note that a battery is not supplied. Adafruit 2821 Feather HUZZAH with ESP8266 WiFi
