SparkFun OpenLog Arduino, Other Infrared JST connector

JST connector

the SparkFun SAMD21 Mini Breakout is even fully supported in the Arduino IDE and libraries for the Arduino Zero

Illumination can be turned on and off with software to conserve power

The output state is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high)

SparkFun OpenLog Arduino, Other Infrared JST connectorThe SparkFun OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 64GB. The OpenLog can store or log huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes. The SparkFun OpenLog runs off of an onboard ATmega328, running at 16MHz thanks to the onboard crystal. The OpenLog draws 6mA when
