Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano
Onboard USB TO UART converter CP2102 for serial debugging
Breakouts the module's UART and I2C interface, for connecting with host boards like Arduino/STM32
Baudrate range: 4800~921600bps (9600bps by default)
Supports DDC (I2C compliant) interface: up to 400KHz (max)
Onboard battery holder, supports ML1220 rechargeable cell, for preserving ephemeris information and hot starts
4x LEDs for indicating the module operating status
Comes with development resources and manual (examples for Raspberry Pi/Jetson Nano/Arduino/STM32)
