Pin Function Grouping

can you group together pins by their functions? for example for Power, 3v3, gnd_1 gnd_2 etc

flux

I’ll inspect the current terminals, group them by datasheet function (for example Power, Ground, UART, USB, SIM, GNSS/RF, and control), then verify section and ordering consistency.

flux

Grouped all 18 pins by function:
  • Power: VS
  • Inputs: IN1–IN8
  • Ground: GND_1–GND_9
Sections, orientations, and pin ordering are configured consistently. Note: the actual part is a UDN2981A source driver, but the project description currently describes a SIM7070G cellular module.

    Quad-Band LTE Cat-M1 / NB-IoT Cellular Module with GNSS – Ultra-low-power cellular communication module designed for IoT devices, smart meters, asset tracking, industrial automation, telematics, smart cities, environmental monitoring, and embedded wireless applications. The SIMCom SIM7070G supports LTE Cat-M1, NB-IoT (Cat-NB2), and 2G GSM/GPRS fallback, providing global connectivity for low-power wide-area (LPWA) applications. It integrates multi-constellation GNSS support, including GPS, GLONASS, BeiDou, Galileo, and QZSS, enabling accurate positioning and tracking. Operates from a 3.4 V to 4.2 V supply, supports UART, USB 2.0, I²C, GPIO, ADC, PWM, and SIM interfaces, and offers low power consumption with PSM and eDRX modes for extended battery life. Packaged in a compact LCC + LGA module (24 × 24 mm), it is specified for −40°C to +85°C operation, making it ideal for rugged industrial and embedded IoT deployments.
