Feature List

Overview

The QuecPython BG&EG series core board (PH-7 (C4-P02)) is a core development board specifically designed for QuecPython with minimal functionality. The core board is designed with a 2.54mm pin arrangement, providing 38 PIN pins, including functional pins and enable control pins. Mainly providing support and convenience for customer development, debugging, and mass production equipment. The core board of the series is applicable to the entire BG95 series, EG915UEUAB, EG915ULAAB, EG912UGLAA and other EG series, including but not limited to the above module models.

Core EVB View

The main components and interface layout of the development board are shown in the following figure.

• Charging and USB: When inserting the Type-C interface to connect to USB, the charging function is enabled by default and cannot be turned off. If the charging function is not used, there is no need to pay attention.
• GNSS: The GNSS function depends on the module model. Taking BG95 as an example, the core board defaults to using active antennas and has already enabled power supply to the active antennas by default.
• SD & SIM Card Slot.
• 38 Pin.
• Antenna Interface。

Quick Start Guide

Hardware Preparation

• Step 1: Required Items

  • Development board
  • USB-C cable (A-to-C)
  • Windows 10 PC
  • Nano-SIM card
  • 4G antenna

• Step 2: Antenna & SIM Installation

  • Attach the provided antenna to the MAIN antenna port.
