GPRS A5/A6/A6C/A7/A20 series module topic

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, with a size of only 22.8*19.8*2.5mm, and a low sleep current of less than 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.

A6 GPRS module is the latest “simple and easy-to-use GPRS transparent transmission module” launched by Anxinke Technology! It is a GPRS data transmission core module, which provides information transmission functions such as serial port to GPRS/short message/voice call, and is widely used in the fields of Internet of Things/vehicle/electric environment detection.

The A7 module is based on the existing A6 module, and the added GPS function can make it have a more powerful application field. Conveniently embedded in numerous hardware products for monitoring, remote control, security, vehicle navigation, and positioning. As well as the current hot wearable devices, it can be applied in fields such as smart positioning shoes for children/elderly, electric vehicle/mountain bike positioning alarm, pet positioning and other fields.
