RAK15001 WisBlock Flash Module Datasheet

Overview

Description

The RAK15001 is a NOR flash module with a 16 MBit (2 MByte) nonvolatile memory. It uses GD25Q16CNIG (16 Mbit) from GigaDevice with standard SPI interface. In this large memory, you can save big data that your applications need to access frequently, like conversion tables, lookup tables or images, and even sound files. Compared to the EEPROM module, the RAK15001 Flash Memory module has fewer write/erase cycles, so it is not ideal as storage for constantly changing data like for sensor readings.

Pin Definition

The RAK15001 WisBlock EEPROM module comprises a standard WisSensor connector. The WisSensor connector allows the RAK15001 module to be mounted on a WisBlock baseboard, such as RAK5005-O. The pin order of the connector and the Pinout Definition is shown in Figure 3.

NOTE

Only the VDD, GND, and Standard SPI related pins are connected to this module.

This table shows WP pin and HOLD pin connections depending on WisBlock sensor slot is used.

Pin Name	Slot A	Slot B	Slot C	Slot D
WP	IO2	IO1	IO4	IO6
HOLD	IO1	IO2	IO4	IO5

The SPI CS, SCK, MOSI and MISO pins are the same on any sensor slot selected.
