Global 4G HAT for Raspberry Pi

The LORDWORLD SIM7600G-H 4G HAT (B) adds LTE Cat-4 connectivity with 2G and 3G fallback to Raspberry Pi boards. It connects through a dedicated pogo-pin header for Zero models or a Micro USB port for other Pi boards and PCs. A SIM slot accepting 1.8 V and 3 V cards enables worldwide mobile access for IoT and maker projects.

Sustained multi-protocol operation

The onboard SIM7600G-H module maintains continuous links for dial-up, voice calls, SMS, TCP, UDP, DTMF, HTTP and FTP sessions. GNSS reception across GPS, BeiDou and Glonass runs alongside cellular traffic, while LBS positioning provides a backup fix. Dual LEDs give immediate visual feedback on network registration and data activity during long deployments.

Check host interface and antenna needs

Verify whether your Pi uses the pogo-pin layout or requires the Micro USB link, and confirm that a compatible cellular antenna is available for the target bands. The board draws power from the host USB connection, so ensure the supply can sustain modem transmit peaks. AT-command control follows 3GPP TS 27.007, 27.005 and V.25TER, so software must implement that command set.

Questions about this item

Does the SIM7600G-H module generate noticeable heat or draw extra power when the 4G link runs continuously?

The board uses the host Raspberry Pi's supply through the pogo pins or Micro USB, so its thermal load stays within the Pi's normal operating envelope.

Which Raspberry Pi models can connect directly to the pogo-pin header without extra cabling?

The dedicated pogo pins match the Raspberry Pi Zero and Zero W GPIO layout; other Pi boards need the Micro USB link.

Will the HAT's USB hub port work with a Raspberry Pi 3 Model B that only has USB 2.0 ports?

Yes, the hub connects over USB 2.0 so it functions normally with any Pi that presents a standard USB-A or Micro USB port.
