“Parade control Systems are happy to right a review of this unit. This is a GREAT little breakout board. We will be using it in part of a larger project for a museum display in the UAE. We are also using the longer range OFS for our vehicle odometry systems used by Universal Studios for their parade float tracking systems that we supply.”
“Really nice little board. Works very well. The snag is that documentation for the chip is scarce and the libraries are pretty basic (because the authors don't have the documentation). Not Pimoroni's fault. But you can get it do the basics stuff. I still recommend it and maybe the libs will get better.
Try
SparkFun_Qwiic_OTOS_Arduino_Library.h
Bitcraze_PMW3901.h // also works for PAA5100
and code from https://github.com/zic-95/PAA5100JE”
“Module is fine. The issue was with writing a driver in C/C++ for Arduino/Particle device. No response on the community - data sheet is very thin on information - in fact there is no explanation of the 'secret sauce' of the commands to setup the device. Lastly, needs to be calibrated because pulses vary according to the distance from the surface it is moving over. Once all that was sorted then it was impressive. Will need fusion with a 3DoF sensor to track movement against external co-ordinates.”
“Worked perfectly out of the box. Replaces the PMW3901 in my indoor robot. Positioning accuracy is much improved. I still see some accuracy variations between hardwood floor and carpet (carpet is more accurate), perhaps having it even closer to the ground can reduce errors. I have it around 3cm off the ground as opposed to the 15mm minimum. Teensy 4.0 Arduino, with 2 breakouts on one SPI bus at 2MHz. Overall, excellent purchase. Will buy again.”
