Photon

The Photon is a tiny Wi-Fi development board that makes it easy to create internet-connected hardware. The Photon is all you need to get started. Power it over USB and in minutes you'll be controlling LEDs, switches, and motors and collecting data from sensors over the internet!

It has 18 digital I/O pins, 8 analog input pins, 2 analog outputs (DAC), 9 PWM pins; UART (Serial), SPI, I2S, I2C, CAN, and JTAG peripherals available. Programmed wirelessly OTA (Over The Air via Particle Cloud), via USB or JTAG. 3.3VDC supply voltage (on board power regulator); can be powered by USB Micro, VIN or 3V3 with 100mA typical current consumption; 300mA peak consumption (during transmit events). Powered by a 32-bit STM32F205 microcontroller, ARM Cortex-M3 architecture, running at 120Mhz, with 1MB of Flash and 128KB of RAM.
