Photon Battery Shield - power module with LiPo charger

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

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

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

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
