Issue when using with RASP PI B+ Model

By Anandasundararaman s from West Bengal, India on July 16, 2018
When trying to use with the Raspberry PI 3 B+ model it does directly fit with the GPIO pins. As new RASP PI B+ has PoE Jumper PIN, GSM Hat's Battery cap is preventing it from proper stack.
Need to use GPIO Extender for proper fit.

    • Q
    • Will the GPS work if Reliance 4G VoLTE card is used on this hat?

      asked by Raseek on December 30, 2019
    • A
    • SIM868 GSM / GPRS + GNSS module is a complete Quad-Band GSM/GPRS module which combines GNSS technology for satellite navigation.It will not work with JIO SIM because it's not having VoLTE support.
