GMOD 64Mbit Serial Flash Memory Breakout SPI

The 64Mbit SPI Flash (Serial Flash) Module is a compact non-volatile memory solution designed for developers, makers, and embedded system engineers. It provides external flash storage for microcontrollers using the SPI (Serial Peripheral Interface), making it ideal for storing firmware, configuration data, logs, fonts, images, and other application data. Documentation for Serial Flash This module is commonly based on SPI serial flash memory ICs (such as Winbond W25 series or compatible) and supports high-speed SPI communication. With a simple pinout and small footprint, it is well suited for prototyping, debugging, and expanding memory in embedded platforms like GLYPH, Arduino, ESP8266, ESP32, STM32, and Raspberry Pi. Supported Interfaces: SPI (Serial Peripheral Interface) SDIO (Secure Digital Input Output) Logic / Control Pins: VCC – Power Supply (3.3V typical) GND – Ground CS – Chip Select CLK – SPI Clock MO (MOSI) – Master Out, Slave In MI (MISO) – Master In, Slave Out SD2 / SD3 – Additional data lines Applications External flash memory expansion Firmware and data storage ESP8266 / ESP32 program storage Data logging and configuration storage Embedded system development Prototyping and testing memory interfaces Features SPI-based serial flash memory module Non-volatile data storage High-speed SPI communication Compact and lightweight PCB design Simple 2.54 mm header interface Compatible with common microcontrollers Ideal for embedded and IoT applications
