Arduino® and Raspberry Pi development boards. It is a development board with a SIM808 module that allows you to use GSM communication and GPS features with your boards. By using this board, you can send and receive SMS, track location, and even create your own mobile phone.
The SIM808 module on the board handles GSM communication and GPS receiver functions.
You can power the board with a 5-26VDC power supply or battery. It is recommended to use a power supply that can provide at least 2A current at voltages below 9V.
Alternatively, you can use single-cell (1S) Li-Po or Li-Ion batteries such as 18650 batteries by using the lithium battery connection on the board. It accepts voltage between 3.5-4.2V.
There are SMA connectors on the board for antenna connection. You need to use separate antennas for GSM, GPS, and Bluetooth.
To start the board, after connecting the power, you need to press and hold the "start" button for 2 seconds.
You can monitor the network connection status of the board through the LEDs on it.
It has a 1.25V/3.3V/5V compatible TTL serial connection (UART) so that you can connect development boards such as Original Arduino® boards, Development Boards Based on Arduino® and Raspberry Pi .
To use the Bluetooth feature, you need to obtain a Bluetooth antenna with an SMA connector. GPS and GSM antennas are included with the product.
Note: This product is IMEI unregistered.
