Good article and explanation on the real-world issues that can be encountered with I2C devices. I wish the author had gone into more detail on how to solve those issues by using discrete sensors instead of breakout boards.
- bambax 6y agoSensors not on breakout boards are very difficult to find (in small quantities) and even more difficult to use.
- pantalaimon 6y agoThose breakout boards are just for experimentation / prototyping. You typically design a proper PCB for the final project and of course you can also buy individual sensors.
- foldr 6y agoYou can easily order them from Digikey in unit quantities. E.g. here is an accelerometer that I've used before: https://www.digikey.co.uk/products/en?keywords=MMA8653FCR1 https://www.digikey.co.uk/products/en?keywords=MMA8653FCR1 Most I2C interface sensors require minimal external components (often just a bypass cap), so they're are quite easy to use without a breakout board. The one non-trivial thing that a breakout board might do for you is level shifting, if you're using a 5V microcontroller.
