Array) packaging technology, which enables easier and more reliable soldering processes compared to a normal LGA (Land Grid Array) package. For product features, see the ZOE-M8 Data Sheet [1]. To determine which u-blox product best meets your needs, see the product selector tables on the u-blox website www.u-blox.com. 2 Design-in In order to obtain good performance with ZOE-M8 GNSS receiver SiPs, there are a number of issues requiring careful attention during the design-in. -
Page 7: Dc/Dc Converter (Only On Zoe-M8Q)
ZOE-M8 series - Hardware Integration Manual Do not add any series resistance greater than 0.1 Ω to the V_CORE supply as it will generate input voltage noise due to the dynamic current conditions. If a DC/DC converter is not used, supply V_CORE with the same supply as used for the VCC. -
Page 8: Interfaces
The TXD Ready functionality can be enabled and configured by using suitable AT commands sent to the u-blox cellular module in question that supports the feature. For more information, see the GPS Implementation and Aiding Features in u-blox wireless modules [5]. -
Page 9: Display Data Channel (Ddc) Interface
For the speed and clock frequency, see the ZOE-M8 Data Sheet [1]. To make use of DDC interface, the D_SEL pin must be left open. The ZOE-M8 GNSS SiPs DDC interface provides serial communication with u-blox cellular modules. See the specification of the applicable cellular module to confirm compatibility. -

Page 14: System Reset (Reset_N)
ZOE-M8 series - Hardware Integration Manual 2.7 System Reset (RESET_N) The ZOE-M8 GNSS SiPs provide a RESET_N pin to reset the system. The RESET_N is an input-only with internal pull-up resistor. It must be at low level for at least 10 ms to make sure RESET_N is detected. It is used to reset the system. - Page 15 ZOE-M8 series - Hardware Integration Manual Pin # Name Description Remark ZOE-M8G Supply voltage Clean and stable supply needed ZOE-M8Q V_CORE Core Supply voltage Connect to VCC if DCDC not used Ground Ensure good GND connection PIO13 / EXTINT External interrupt Leave open if not used.
