The code in the above Documents->Firmware link is out-of-date (Version 1.0 code).</p>

The Description Note above says the the jumper can be used to use the I2C address of 0x18 or 0x19, depending on the jumper setting.</p>

David12 on COM-15093 - SparkFun Qwiic Single Relay David12urn:uuid:9961a585-3ef4-6d59-eb02-9598d8ca9dba2020-03-27T21:44:53-06:00<p>I am trying to use this on a Raspberry Pi. It appears the EEPROM that is storing data such as the address can be corrupted and I can no longer see or use the relay on the i2c bus. When I execute <code>i2cdetect 1</code> shell command in raspbian the entire bus shows all addresses in use even though only the relay is connected. It appears it became corrupted after I tried to scan the address with <code>i2cdump 1 0x18</code>. It did show up correctly on the bus before I executed that command. The i2c bus works fine when I have other i2c devices on the bus without the relay connected.<p>How can I fix/reset the relay?</p></p>

The source code, examples, installation information and documentation are available on GitHub.<p>https://github.com/fourstix/Sparkfun_CircuitPython_QwiicRelay</p></p>

Customer #1379917 on COM-15093 - SparkFun Qwiic Single Relay Customer #1379917urn:uuid:7481120d-3017-64b3-b59c-8ea8a80982282019-04-02T16:31:10-06:00<p>I'm having some trouble with this relay. When I don't have anything hooked up to the terminals, it turns on and off fine. However, when I have a 12v supply attached, the relay turns on, but won't turn off. While it's in this "stuck on" state, it also won't return its current status (send 0x05, and then request byte). Anybody had this issue?</p>
