ERF3002, IoT Development Platform, Arduino shield with Quectel BG77 module - easyRF
August 16, 2021
The ERF3002 Arduino shield features the BG77 of Quectel Wireless Solutions.
The BG77 is an ultra-compact LPWA module supporting LTE Cat M1, LTE Cat NB2 and integrated GNSS. It is fully compliant with 3GPP Rel-14 specification and provides maximum data rates of 588 kbps downlink and 1119 kbps uplink.
It features ultra-low power consumption by leveraging the integrated RAM/flash as well as the ARM Cortex A7 processor supporting ThreadX, achieving up to 70% reduction in PSM leakage and 85% reduction in eDRX current consumption compared to its predecessor.
For easy evaluation of this low power consumption, there is an onboard current measurement system that provides mA accuracy (Range: 0.5mA ~ 500mA). This current monitoring system is a valuable tool to analyze the modules current consumption during startup, Idle mode, Connecting, and transmitting data.
Finally, there is also a temperature sensor on the shield to provide all the necessary tools to start building your application without having to design any hardware.
The ERF3002 combines the power of the BG77 with an easy to use Arduino platform and allows for rapid testing and development.
