QWIIC Quad Solid State Relay not adressing properly

Qwiic System
1

Hello,

I bought two QWIICc Quad Solid State Relay (part number: 16833, link: https://www.sparkfun.com/products/16833)

I also bought four: Qwiic Cable - Breadboard Jumper (part number: 14425, link: https://www.sparkfun.com/products/14425)

I would like to control these relays with a Raspberry Pi 4, but I cannot get it to work. My problems is exactly the same to this topic: viewtopic.php?f=105&t=55721

When I connect the Raspberry pi to an Adafruit PCT2075 temperature sensor (I2C), and I run i2cdetect, it gives confirmation that the 0x37 adress (as expected) is connected. Therefore the I2C is correctly configured.

I followed this tutorial for configuring I2C (https://www.artekit.eu/enabling-the-i2c … pberry-pi/)

However when using the SAME Raspberry Pi, connected the SAME manner, running i2cdetect, nothing is detected. This is the case for both Quad relays (16833). The power led on the board is lit, showing it receives power.

I connected the Raspberry Pi in the following manner to the breadboard jumper (14425):

3.3V to red cable

GPIO 2 (SDA) to blue cable

GPIO 3 (SCL) to yellow cable

GND to black cable

I also switched the SDA and SCL to no avail.

Do I need to use an external power supply? Or can I connect the red cable to a 3.3V pin of the Raspberry Pi? What can I do to get this working?

This is probably bad firmware; head over to www.sparkfun.com/returns, fill out the short form, and we’ll send out some replacements ASAP.

Happy sparking!

Which batch-number was this? (printed on the Sparkfun carboard box)

Same problem here with 2 cards, batch = #139648

It looks like we had missing firmware on the batch. Fill out a return ticket and we can get the issue taken care of:
