Introduction
The
X-STM32MP-GNSS1
expansion board for the global navigation satellite system (GNSS) receiver which embeds the
following devices:
•
The
Teseo-LIV3FL
module for Low power GNSS positioning along with sensor for position accuracy.
•
The
ISM330DHCX
iNEMO 3-axis accelerometer and 3-axis gyroscope
•
The
IIS2MDC
3-axis magnetometer
•
The
ILPS22QS
pressure sensor
•
The external LNA and SAW filter
•
The external antenna amplifies any weak signals to improve the quality of data received.
•
Switches & LEDs present
The
X-STM32MP-GNSS1
interfaces with the STM32MP157F-DK2 board via a 40-pin GPIO connector, using I²C, SPI, and
GPIO interfaces.
The
X-STM32MP-GNSS1
expansion board is compatible with both the STM32MP157F-DK2 and Raspberry Pi GPIO expansion
connector layout.

Page 6: Teseo-Liv3Fl Module Section
UM3237 Teseo-LIV3FL module section Teseo-LIV3FL module section Teseo-LIV3FL module is based on the TESEO III single-die standalone positioning receiver IC, which is a low-power tiny GNSS receiver. Within its 9.7 x 10.1 mm tiny size, the Teseo-LIV3FL offers superior accuracy as it has integrated temperature, compensated crystal oscillator (TCXO), and a reduced time to first fix (TTFF) due to its dedicated real-time clock (RTC) oscillator. -
Page 7: Lna (Low Noise Amplifier)
UM3237 LNA (low noise amplifier) LNA (low noise amplifier) An external low noise amplifier (LNA) is also present to amplify the weak signals received. The low noise amplifier (BGA824N6) ranges from 1550 MHz to 1615 MHz. It provides a 17.0 dB gain and 0.55 dB noise figure at a current consumption of 3.8 mA. -
