pHAT-GSM

  • The pHAT-GSM is a 2G quad-band GSM/GPRS module for SMS and data communication over the mobile phone network. Specifically designed for the Raspberry-Pi Zero the pHAT-GSM features I2C communication to leave the Raspberry-Pi UART for other functions eg. sensors etc. pHAT-GSM features full AT command control over the embedded I2C to UART bridge allowing the Raspberry-Pi to create GPRS sessions and send/receive SMS texts.

  • All our products are designed and manufactured in the UK.

  • Available from the following distributors:

    Lextronic (France)
    Farnell inOne

  • Product code : pHAT-GSM

RoHSRoHSMade in the UK

Description

The Designer Systems pHAT-GSM pHAT-GSM is a quad-band GSM/GPRS module that works on frequencies GSM850MHz, EGSM900MHz, DCS1800MHz and PCS1900MHz supporting GPRS class 12 data and Small-Message-System (SMS) functionality. Specifically designed for the Raspberry-Pi Zero user (can also be used on all the other Raspberry-Pi variants) the pHAT-GSM features I2C communication to leave the Raspberry-Pi UART for other functions eg. sensors etc. pHAT-GSM features full AT command control over the embedded I2C to UART bridge allowing the Raspberry-Pi to create GPRS sessions with uplink and downlink transfers at up to 85.6kbps to support standard Internet service protocols. The compact form factor, low power consumption and extended temperature range make pHAT-GSM a best choice for M2M and M2H applications when using the Raspberry-Pi modules.

Features

  • Raspberry Pi Zero standard form factor for simple integration into any Raspberry Pi project.
