Description

The RAK15000 WisBlock EEPROM module, part of the RAKwireless WisBlock series, is a serial EEPROM module with an I2C interface. Designed to work at low power mode, the standby average consumption is lower than 3 µA ( VCC = 5.5 V ). The RAK15000 uses Microchip AT24CM02 that provides 2,097,152 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM), organized as 262,144 words of 8 bits each.

Pin Definition

The RAK15000 WisBlock Sensor module comprises a standard 24-pin WisConnector. The IO WisConnector allows the RAK15000 module to be mounted on a WisBlock baseboard, such as the RAK5005-O. The pin order of the WisConnector and the pinout definition is shown in Figure 3.

NOTE

Only the I2C related pins, 3V3_S, and GND are connected to this module.
