Photon Battery Shield - power module with LiPo charger

Module with 9DoF LSM9DS1 sensor (3-axis accelerometer, 3-axis magnetometer, 3-axis gyroscope). It has a derived I2C interface and is supplied with the voltage of 3.3 V. SparkFun DEV-13629

Photon Micro OLED Shield breaks out a small monochrome, blue-on-black OLED to use with your Photon module. It’s “micro”, but it still packs a punch – the OLED display is crisp, and you can fit a deceivingly large amount of graphics on there. DEV-13628

Particle’s IoT (Internet of Things) hardware development kit, the Photon, provides everything you need to build a connected project. Particle has combined a powerful 120Mhz ARM Cortex M3 micro-controller with a Broadcom Wi-Fi chip in a tiny thumbnail-sized module called the PØ (P-Zero)

Prototype board designed to cooperate with Particle Photon. The board has prototype holes with a 2.54 mm pitch and pins of the I2C interface. SparkFun DEV-13598

IoT development board the size of Arduino, equipped with an ARM Cortex-M3 processor (STM32F205) and a Wi-Fi communication module (with an integrated antenna and uFL connector). SparkFun DEV-13321

Module with pressure, humidity and temperature sensor. It uses the I2C interface and allows the connection of additional wind sensors via the RJ11 connector. SparkFun DEV-13674

The board features bi-directional motor control using a TB6612 dual H-bridge, so it can control one stepper motor or two brushed DC motors with 4.5-13VDC power and about 1A current draw per motor. Adafruit 2653
