We purchased one unit and quickly had it up and running with an ATMEGA88.
This is a quality manufactured product, you can't do better. It is cost effective and saves you many hours trying to source the parts and make a circuit board to mount it.
Of the many similar sensors offered by AVAGO, (now PIX-ART), the ADNS 9800
is among their higher performance ones. It has a programmable counts per inch
feature and 16 bit X-Y position registers.

The board's quality is excellent!
If you use the sensor in a 3V3 environment like in combination with an STM32F4xx, you can simply connect it to your existing application, write your own source code (or port the existing Arduino code if you prefer that) and you're done!
In contrast to the ADNS2610 that I previously used, this sensor delivers very accurate motion data at a much higher resolution.
In combination with some simple maths, this sensor enabled me to really improve my robot's motion control and navigation system.

Sensor board works pretty good. Board is designed to accommodate sensor's I/O voltage (3.3 volts max.) and can work with 5V as well as 3.3 Volt logic chips. This is pretty convenient. Chip itself is very fast, runs at 49 MHz and does the job excellent. Highly recommended.

Both that I have ordered arrived promptly and function well. It worked much better than my dead-bug proto-board attempt. I'm interfacing it via an MCP2210 connected to a small linux computer using the mcp2210 driver I developed https://github.com/daniel-santos/mcp2210-linux). Hopefully, I'll churn out an spi protocol driver for the adns 9800 as well as the 3090 soon too.
Pictured is my current prototype environment including John's ADNS 9800 board inside a little project box with two ribbon cables attached. Next to it is my failed attempt to make a prototype of the ADMS 9800 (I may have fried the chip or otherwise shorted something because it always reads a ground frault via the SPI). Also pictured is my current 3090 board (missing an oscilator, LED and transistor) and they are all attached to an MCP2210 breakout board.
