Still good after all these years

For ESP8285 Development Board

Noticed the last reviews a while ago so here's something newer.

Ran out of the packaging straight away, but I wasn't sure what program it was running. Summarizing the documentation some tips to program with Arduino 2.0.4 from my notes:

from: https://github.com/esp8266/Arduino had to put: 'https://arduino.esp8266.com/stable/package_esp8266com_index.json' into preferences/Additional
boards Manager. Then in boards manager install 'esp8266 by ESP8266 Community'
Then plug in and at the top left set board 'Generic ESP8285 Module' and select xxxD800bla bla for the port
Set Serial Monitor to 115200 baud
To program press and hold boot, then tap reset, release boot, then program.

Worked great with range out of the house into the garage with a 1.25 inch wire for antenna.

Thanks for the thorough review! Hard to compete with the $2 ESP8266 clones availabe on aliexpress. But I have used this little board myself for many projects and still think it is a bargain even compared to the cheaper Chinese variants. I am glad it is working well for you!

I bought this! I love it!

For AS7331 UVA/B/C Light Sensor Breakout

Processing + shipment was super fast.
:To Developer, thanks, good work, once again a work of electronic art.

Thanks for the kind words. I am having more of these produced since the demand seems to be there for this kind of light sensor.

Great electronic compass sensor

For MAX32660 Motion Co-Processor

I've been developing robotic sailing drones for about 5 years. In that time the design of my controllers has gone through an number of evolutions. This is the fifth iteration with a new compass sensor, and the USFS MAX32660 is the best one yet.
I have spent a lot of time working with i2C devices like MPU-9250, BNO 055 and BNO 080, and struggled to get useful a magnetic bearing from them.
I bought the USFS - LSM6DSM + LIS2MD, and that was the best one to date, that I had used in the last sailing drone and did many hours at sea.
Then I stumbled upon the USFS MAX32660.
I've now incorporated the USFS MAX32660 into my new design and the accuracy straight out of the box is much better than I've seen before in a magnetic heading sensor.
I'm using this with a Teensy 3.6 and using the sample code provided by Gregory Tomasch.
I'm still working toward live trials, but so far its looking good. I do still use the MPU-9250s as low cost long-range (15 to 20mm) magnetic angle sensors within the sailing drone, and they are good for that, but I struggled to use them for a magnetic heading.
The USFS MAX32660 is more expensive than most I2c devices with magnetic heading capability, but if you know what you want, and you just want to get a result without much trouble, then it is a good solution.
I would definitely go to this device again for any projects requiring an electronic compass, ahead of all the others I have previously used.

Thanks for the detailed review and kind words!

We too were unsatisfied with the commercial offerings in this space so we designed our own. We believe (and have demonstrated) that the USFSMAX is simply the most accurate absolute orientation estimation engine at this size and price. We are delighted that you agree!

The USFSMAX Module + carrier is even better.
