The simpleRTK3B Micro Unicore is ArduSimple’s smallest form factor millimeter-level OEM RTK GNSS receiver board, based on the Unicorecomm UM980, UM981 or UM982 modules and providing multi-constellation and multi-frequency tracking. The easy-to-integrate and reusable module allows you to accelerate project development without risk, as it can be removed from the main PCB in case of design or production errors.
The module is available in through-hole or surface-mount variants.
