The ATWINC1500-MR210UB from Microchip is a low power 2.4GHz 802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n WiFi IoTInternet Of Things module that integrates a Cortus APS3 32-Bit processor with 4MB SPISerial Peripheral Interface Flash memory, PAPower Amplifier, LNALow Noise Amplifier, transmit-receive switches, power management, and a uFL connector for an external antenna. It supports data rates up to 72.2Mbps and WEPWired Equivalent Privacy (WEP) is an encryption security protocol for 802.11 wireless networks to protect the information you send and receive over a wireless network. WEP was ratified as a Wi-Fi security standard in September of 1999./WPAWi-Fi Protected Access (WPA) is an encryption security protocol for 802.11 wireless networks to protect the information you send and receive over a wireless network. WPA was released in 2003 as a replacement to the increasingly apparent vulnerabilities of the WEP standard./WPA2Wi-Fi Protected Access 2 (WPA2) is an encryption security protocol for 802.11 wireless networks to protect the information you send and receive over a wireless network. WPA2 was released in 2004 as a replacement of WPA. encryption. You can connect to your own WiFi networks or create your own with "Soft APA WiFi Access Point (AP) is a device that creates a wireless local area network, or WLAN, and acts as a central hub that allows other devices, such as smartphones or computers, to connect to it over WiFi." mode, where it becomes its own access point.

The ATSAMD21G18 microcontroller from Microchip is a 32-bit Single-Core 48MHz ARM Cortex-M0+ with 256KB Flash and 32KB SRAMStatic Random Access Memory (no EEPROMElectrically Erasable Programmable Read-Only Memory). Having a separate microcontroller chip from the WiFi module has the benefit of not yielding all the time to the WiFi core, giving full reign of the microcontroller processor and timing.

The ATSAMD21G18 chip pins are broken out in the Feather board to pin through holes with 0.1" (2.54mm) spacing. All of the I/O pins are 3.3V (max) with 20x GPIOGeneral Purpose Input Output, 8x PWMPulse-Width Modulation, 10x analog inputs (12-bit ADCAnalog-to-Digital Converter (ADC, A/D, or A-to-D)), 1x analog output (10-bit DACDigital-to-Analog Converter (DAC, D/A, or D-to-A)), 3x SERCOMS that can each do UARTUniversal Asynchronous Receiver-Transmitter/I2CInter-Integrated Circuit. Also referred to as IIC or I²C./SPISerial Peripheral Interface. The ATSAMD21G18 chip also has built-in USB with USB-to-UART program and debug capability, so there is not need for a separate USB chip for the Micro USB connector.

The Feather board can be powered with 5V using the Micro USB connector or the JST PH jack with a 4.2V/3.7V LiPo/Li-ion battery. The board will automatically switch over to USB power when its available and recharge the battery using the MCP73831/2 Charge Management Controller chip. The battery connector is passed through a voltage divider to an analog pin (GPIO 9), so you can measure and monitor the battery voltage to determine when you need a recharge.

The boards come with a reset button and 4x LEDs. On both sides of the Micro USB connector are a battery status yellow LED and pin 13 general purpose red LED that the user can control. On both sides of the WiFi module are a green LED that lights when WiFi is connected to an SSIDService Set Identifier (SSID) is a unique sequence of characters that uniquely names a Wi-Fi network. A SSID is sometimes referred to as a network name. and a yellow LED that blinks during WiFi data transfer.

The size of the board is 53.65mm x 22.8mm (2.1in x 0.9in) without headers soldered in.
