Описание
ZOE-M8Q is a highly accurate, miniature tile with a72 channel GNSS receivercapable of receiving signals fromGPS, GLONASS, BeiDouandGalileo. It communicates viaSPI / I2CorUART. It has aQwiicconnector. There is a rechargeable RTC battery on the board, which reduces time-to-first-fix. Power supply voltage is3.3 V.
On the back of the board there are three jumpers: I2C used when using multiple I2C devices. The LED jumper deactivates the power LED when connected. The SPI jumper activates SPI communication after a short circuit, by default the module works in communication with I2C.
GPS module outputs ZOE-M8QThe module communicates via the I2C / SPI or UART interface. In addition, the module has a Qwiic connector for direct connection toQwiic overlays.
