COM.GPS is a satellite positioning module in the M5Stack stacking module series. It is developed based on the NEO-M8N module and is equipped with an active antenna. The NEO-M8 can spend a small amount of time, conduct high-sensitivity acquisition, and keep the system low power consumption. NEO-M8N integrates the 72-channel u-blox M8 GNSS engine, supports multiple GNSS systems: BeiDou, Galileo, GLONASS, GPS / QZSS, allowing simultaneous reception 3 Data from a GNSS system. Programmable FLASH is integrated inside the module, which can read and write data. The module's high sensitivity, small static drift, low power consumption and compact size are very suitable for applications in vehicles, handheld devices such as PDAs, vehicle monitoring, mobile phones, cameras and other mobile positioning systems. The UART communication protocol is used between the M5Core and the GPS module, and the serial port connection pins can be modified through the dial switch on the back.
If you want to change the serial port baud rate, please click ( u-center-just-for-Windows ).
Note: In order to get a good signal from the GPS module, please place the module outdoors when using it.
UART protocol: baud rate (default is 9600bps), data bit (8 bits), start bit (1 bit), stop bit (1 bit), check bit (none).
When using with the FIRE main control, due to the PSRAM pin conflict, please switch the Module base DIP switch pin to TX(0/13), RX(5/15) when using it.
When used with Core2 series main control, due to the different order of the base pin array, COM.NB-IoT base pins TX(16), RX(17) correspond to the actual pins TX(14) of the Core2 main control ,RX(13).
Note: When using the CORE2 or CORE2-FOR-AWS main control to drive the module, please use the DC power input of the base and set the power mode to input mode (refer to the code below), otherwise it will not start normally. //mbus_mode_t: //kMBusModeOutput: use USB or battery power //kMBusModeInput: Use external power supply 5V, or DC interface M5.begin(true, true, true, false, kMBusModeInput);
The right dial switch is invalid for this module, no need to set.
