Septentrio announces an important addition to the open-source resources for their GPS/GNSS module receivers: mosaicTM wireless or simply mowi. It combines the Septentrio mosaic-X5 or mosaic-H module receiver with a dual-mode Bluetooth and integrated Wi-Fi from the well-known ESP32- WRover programmable module by Espressif Systems. It is an addition to the already existing mosaicHAT board, designed on the Raspberry Pi platform.
The mowi project facilitates accurate and reliable GNSS positioning for robotic and autonomous devices, on a hardware level. Numerous engineers today use the ESP32 and the multiple libraries available for Internet-of-Things (IoT) prototyping. The mowi board is an easy way for integrators to get started with Septentrio’s mosaic-X5 or mosaic-H heading module receivers. The mowi board can be used on its own or plugged into a mobile computer such as Raspberry Pi or Arduino to deliver high-accuracy positioning with high update rates, ideal for machine navigation, monitoring, or control. The internet connection via Wi-Fi or Bluetooth enables numerous industrial IoT applications, simplifying the connectivity to mobile data for the delivery of GNSS corrections needed for cm-level RTK positioning.
On top of the wireless communication, the small 47.5×70 mm board can host IoT applications in its internal memory. It has onboard logging and exposes interfaces such as USB, serial communication, and general-purpose pins. The schematic’s reference design, PCB layout, and documentation are openly available for prototyping or further customization.
The mowi open-source project is available to the community on the Septentrio GitHub repository.
