Microstack: a new range of complementary accessories for Raspberry Pi
The Microstack range is a new range of accessories for Raspberry Pi B, Raspberry Pi A+, Raspberry Pi B+ and now the Raspberry Pi 2 model B designed by the creators of the PiFace expansion boards, already well known among Raspberry Pi users.
When designing their new accessories for Raspberry Pi, these PiFace geniuses wanted to continue with the idea of stackable blocks that are easy to both connect and implement.
The range currently includes a base board (essential for the other expansion boards to operate) and 2 modules for Raspberry Pi: one GPS module and one 3-axis accelerometer. Simply connect the Base Board to your Raspberry Pi to be able to rapidly install one of these modules, or even both modules at once!
3-axis accelerometer for Raspberry Pi: 1 module, 2 configurations
The 3-Axis Accelerometer for Raspberry Pi is a small, very low-power and ultra-high-speed Microstack module with many applications.
It can for example detect orientation, shaking on input devices and physical movements of all kinds (free fall, shock, trajectory, etc.). The accelerometer module’s built-in MMA8491Q acceleration sensor offers 2 possible configurations: a 45° tilt sensor or a 14-bit digital output accelerometer. This module can be used in the design of 3D motion controllers and embedded navigation systems for drones and mobile robots.
