Description

Main Features and Parameters
  • Interface and Communication: Uses the SPI communication interface, typically defaulting to pins D5 (CLK), D6 (MISO), D7 (MOSI), and D8 (CS) for communication.
  • Voltage Compatibility: Features an onboard 3.3V voltage regulator and a level shifter chip (such as the 74LVC125A). This allows it to be compatible with both 3.3V logic and safely communicate with 5V logic controllers, protecting the SD card from high-voltage damage.
  • Stackable Design: The board is designed with pin headers on both sides, allowing it to be directly stacked and plugged into the D1 mini mainboard, saving space and ensuring a stable connection.
  • Power Supply: Can be powered by the D1 mini mainboard (5V or 3.3V), and the onboard circuitry converts it to the stable voltage required by the SD card.

  • We focus on three core product categories to meet diverse market demands:

     

    1、Passive Components: We offer a comprehensive range of resistors, capacitors, inductors, and connectors, backed by stable stock and competitive pricing to support your continuous production needs.

     

    2、Integrated Circuits (ICs) & Microcontrollers: Our portfolio features high-performance chips, including the ESP32 series, MCUs, and logic ICs. All components are sourced from authorized distributors to ensure guaranteed quality and authenticity.

     

    3、PCB & PCBA Solutions: We provide complete supply chain support for printed circuit boards, ranging from prototype fabrication to mass production assembly, serving the IoT, consumer electronics, and industrial sectors.
