The document introduces a product series called GC864, which is one of the smallest GSM/GPRS quad-band modules with industrial connectors in the market. The product has an ultra-compact design and extended temperature range, making it suitable for medium-volume m2m applications and mobile data devices. It also has additional features such as integrated TCP/IP protocol stack and serial multiplexer.
The GC864‑QUAD and GC864‑PY are among the smallest GSM/GPRS quad‑band modules with industrial connectors, offering an ultra‑compact design and an extended temperature range for medium‑volume M2M applications. Features include an integrated TCP/IP protocol stack, serial multiplexer, and for the PY variant, a built‑in Python interpreter with SPI and I²C interfaces for external peripherals.
Both modules support Over‑the‑Air firmware updates via Telit’s Premium FOTA Management and comply with RoHS directives. They provide a range of interfaces such as an 80‑pin Molex connector, UART, audio I/O, and a 50 Ω antenna connector, and are approved for CE, FCC, PTCRB, and other regional certifications.
