  • Answering my own question, it DOES work on 3.3V, even though the HT16K33 IC is designed for 5V. However, you can NOT use the Qwiic Shield with a modern ARM based Arduino board without modification. The Qwiic Shield, as shipped, only works with the Uno, which has its SDA and SCL signals on the A4 and A5 pins.

  • Will this display work with a 3.3V Arduino board such as the Adafruit Metro M4 Express using the Sparkfun Qwiic Shield? Or does it require 5V?

  • Bob Dylan just felt a disturbance in the force. Has no idea why.

  • Hi, does the MCP9600 support multi-address configuration on the I2C bus, or does the Qwiic system have a way of supporting multiple I2C devices with the same address? My goal would be to have multiple TCs in a system. Thanks

No public wish lists :(
