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
Support protocols including TCP/IP, HTTP(s), MQTT(s), FTP(s), and SSL
Support dial-up, telephone call, SMS
Support 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.
The Raspberry Pi PoE+ HAT is a Power Over Ethernet (PoE+) accessory for the Raspberry Pi 3B+/4B. Compared to its predecessor Raspberry Pi PoE HAT, it features better cooling effect, implementing the 802.3af/at standard with 5V DC/4A larger power output, providing enough power for both Raspberry Pi 3B+/4B at max load and other peripherals at the same time.
By using this small HAT and some proper 802.3af/at-compliant power sourcing equipments, it is possible to provide both network connection and power supply for your Raspberry Pi in only one Ethernet cable.
The Pico-UPS-B is a dedicated UPS (Uninterruptible Power Supply) module designed for Raspberry Pi Pico. It incorporates Li-po battery switching charger with power path management, and voltage/current monitoring chip, allows monitoring the battery operating status via I2C bus. What is more, the male pin header make it possible to "stack" other modules on top.
Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series boards
Incorporates Li-po battery switching charger with dynamic power path management, more stable power supply
I2C bus communication, monitoring the battery voltage, current, power, and remaining capacity in real time
Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, more safe and stable
Onboard recharging indicator, power indicator, easy to check the battery status
Come with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
