This small GPS module is an ideal module for Arduino. The NEO-7 series is characterised by the exceptional performance of the highly sensitive u-blox 7 GNSS (GPS, GLONASS, QZSS and SBAS).

Ever needed a microphone for your project. This tiny little board will fulfill all your needs - it is not only mobile, but as well easy to connect. A low power, efficient, omnidirectional AMP401 microphone has an analog output. It works great for near and long range uses and is particularly suitable for a mobile projects given its extremely low energy consumption. You can use it in a range of applications - we can see it used in smartphones, cameras or electronic nannies.

 Master Slave Bluetooth Modul for Arduino iOS Android. The HM10 supports Bluetooth 4.0 (low energy) and therefore has a relatively low power consumption.
