Compass TinyShield - ASD2511-R-C tinycircuits.com/collections/sensors/products/compass-tinyshield DESCRIPTION This TinyShield features the high performance and low power Honeywell HMC5883L 3-axis compass. The HMC5883L includes state-of-the-art, highresolution HMC118X series magneto-resistive sensors plus an ASIC containing amplification, automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. The Compass TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.

Previous versions of this board will look a bit different and have the board number ASD2613-R, however they are functionally equivalent to this updated version and the compass circuitry is identical. Earlier versions also had two interrupt pins broken out to solder points, these are not present on the current version of this board. 2/2
