Description

Waveshare SIM800C GSM/GPRS/Bluetooth HAT is a compact Raspberry Pi GSM HAT for SMS messaging, GPRS communication, and Bluetooth data transfer. This Waveshare board combines the SIM800C GSM/GPRS/Bluetooth HAT design with 2G connectivity and onboard Bluetooth, making it useful for message-driven IoT projects, low-bandwidth remote nodes, and short-range wireless links.

The Waveshare SIM800C GSM/GPRS/Bluetooth HAT is especially useful when a Raspberry Pi GSM HAT needs both cellular messaging and local pairing in the same build. Because the SIM800C GSM/GPRS/Bluetooth HAT supports calls, SMS messaging, GPRS communication, and Bluetooth data transfer, this Waveshare board is a practical fit for kiosks, POS devices, telemetry terminals, and embedded control systems.
