DESCRIPTION
LTE Cat-1 HAT for Raspberry Pi
Enabling LTE Cat-1 / 2G communication & LBS positioning based on A7670E
Features at a glance
The A7670E Cat-1 HAT is an LTE Cat-1 module, which supports wireless communication modes including LTE-TDD, LTE-FDD, GSM, GPRS and EDGE, with up to 10Mbps downlink rate and 5Mbps uplink rate. It supports Windows/Linux operating systems and multiple network protocols. The module size is the same as SIM7000/SIM7070 series, and the AT commands is mostly compatible with SIM7600 series. It is suitable for IoT applications like remote information processing, monitoring devices, POS, industrial routers, remote diagnosis, and so on.
- Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
- Supports protocols including TCP/IP, HTTP(s), MQTT(s), FTP(s), and SSL
- Supports dial-up, telephone call, SMS
- Supports LBS base station positioning, it is able to get the approximate position info via mobile network
- TTS (Text To Speech) feature, texts in Chinese/English can be converted into spoken words
- Onboard USB interface, for testing AT Commands, network communication, and so on
- Onboard audio jack for sound recording, making telephone call, listening the TTS resulting speech, etc.
- Breakout common used control pins of the A7670X module, make it easy to connect with hosts boards like Arduino/STM32
- SIM card slot, supports 1.8V/3V SIM card
- 2x LED indicators, easy to monitor the operating status
- Onboard voltage translator, operating voltage can be configured to 3.3V or 5V via jumper
- Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)
Standard Raspberry Pi 40PIN GPIO
Compatible with Raspberry Pi series boards
Dial-up on Windows/Linux
LTE Cat-1: up to 5Mbps (uplink) / up to 10Mbps (downlink) *
EDGE: up to 236.8Kbps (uplink / downlink) *
GPRS: up to 85.6Kbps (uplink / downlink) *
* stands for idealized data rate, the actual data rate depends on factors like network coverage, traffic congestion, base station condition, etc.
