Building blocks – sensors and development boards for IoT
The Arduino series has a wide collection of development boards that vary in size, pins, and communication technologies. In this chapter, I will use an Arduino MKR GSM 1400 development board, as it’s compact, battery-enabled, and provides the support of GSM/3G/4G. Figure 5.1 shows the pinout diagram for the MKR GSM 1400.
Figure 5.1 – Arduino MKR GSM 1400
Arduino MKR GSM 1400 provides 7 analog pins and 14 digital input/output pins, with built-in battery charging and a LiPo battery connector for standby power, which helps developers build prototypes and solutions for remote monitoring/operations without worrying about power backups.
