A5 is a complete quad-band GSM/GPRS module with built-in China Mobile eSIM card. Using SMD package, the product can be produced quickly through standard SMT equipment. It has the industry's most competitive package size and ultra-low energy consumption technology, the size is only 22.8*19.8*2.5mm, and the sleep current is as low as 3mA. It can be widely used in various IoT applications, suitable for home automation, industrial wireless control, wearable electronic products, wireless location sensing devices, wireless positioning system signals and other IoT applications. It is an ideal solution for IoT applications.

The A6 GPRS module is a GPRS data transmission core module that provides information transmission functions such as serial port to GPRS/short message/voice call, and is widely used in the Internet of Things/vehicle/electric environment detection fields.

A9 is the latest GSM/GPRS module from Essence. Compared with A6, A9 has a higher level of integration, and the cost reduction of the core chip makes the whole solution more cost-effective. It provides information transmission functions such as serial port to GPRS/short message/voice call, which is widely used in the fields of Internet of things/vehicle/electric environment detection.

A9G is a complete quad-band GSM/GPRS+GPRS/GPS module. Compared with A7, A9G is more integrated, and the cost reduction of the core chip also makes the whole solution more cost-effective. It is convenient to apply to various IoT hardware terminal occasions.
