【Overview】

[] Zero 4G Cat1-Hub Expansion board

[] Probes for power supply and communication,no USB cable required, saving space!

【Description】

[] RPi Zero 4G Cat.1 expansion board, with Raspberry Pi zero size design, its positioning holes are exactly the same; it adopts Nano SlM card slot (and reserved eSlM chip position),supports 4G, downlink 10Mbps uplink 5Mpbs, can meet most Medium-speed loT applications'request.

[] The expansion board is connected to the Raspberry Pi Zero through four gold-plated probes (the MicroUSB data port on the Zero is no longer available), so that the expansion board has three UsB2.0 host interfaces in the form of USB-C (optional USB-C to USB -A adapter cable) is used to expand USB peripherals such as keyboard and mouse.

[] The 4G Cat.1 module adopts IPEX first-generation antenna interface, and can also be connected to SMA antenna. Iin order to facilitate debugging, the expansion board also leads to the general serial port of the module, the debugging serial port and the reset button.

[] The power supply can from the Micro power port of Zero or the USB-C port of the expansion board (choose one of the two, it is recommended to use the USB-C power supply of the expansion board).

[] RPi zero Cat.1 expansion board supports all versions of Raspberry Pi zero series, including zero, zero W, zero WH and zero2 W.

【Working mode】
[] Default mode:
Matched with the Raspberry Pi zero series board, the thimble for communication and provides power, with 3*USB2.0 and 1* 4G LTE. The 4G module uses a USB port and can talk with AT commands.

[] Optional modes (NO technical support):

[] Communication with the microcontroller serial port:
The board needs to be powered by the power supply via USB-C. The onboard 4G serial port or GPs serial port (4G with GPS function) can be connected to the serial port of the microcontroller such as STM32 for communication (the software user can adjust it by himself, our company does not provide technical support ); and the 3*USB ports are invalid; the serial port voltage is 3.3V.

[] Communication with the computer:
2 resistors(0R) need to be welded on the back of the board. The USB-C port of the onboard power supply can be connected to the computer to implement a USB HUB function, that is, 4G networking, and all 3*USB2.0 channels are available. But if you want to switch to Raspberry platform, the originally welded resistor needs to be removed.
